Joints in Masonry Module MM13 Habitat Polytech, Richmar Foreword The devastating earthquake of January 26, 2001 caused tremendous damage to the lives and property of the population living in the northern and northwestern districts of Gujarat. In the wake of this humanitarian tragedy a large number of local, national and international organisa- tions engaged in relief and rehabilitation operations. A diverse range of strategies was adopted to meet the urgent needs of the suffering population to rehabilitate their lives and reconstruct their houses. In line with its principles, Swiss Red Cross promoted a process-oriented and community-centred approach, taking into consideration the actual needs of the people and the specific conditions of the area. Accordingly, the rural villagers, especially women, were identified as a pro-active force building on their own strength rather than becoming passive recipients of external aid. After a participatory assessment in three remote villages Antarnesh, Bakutra and Gadsai of Patan district, Swiss Red Cross decided to contribute to the rehabilitation of the lives of nine hundred families, through providing them with new, earthquake save houses, kitchens, toilets and water harvesting systems, called Naya Ghar (New housing). This infrastructure-focused improvement was mainly seen under the aspect of securing people’s livelihood by creating employment opportunities in the building sector. The following complementary organisations were engaged in the Swiss Red Cross and Swiss Solidarity supported Naya Ghar’ Project: n SEWA, (Self-employed Women’s Association) with its wide network of more than 500‘000 members in Gujarat was selected as the main local project implementing partner organisation. n DA (Development Alternatives), an India based NGO, in cooperation with Skat Consulting from Switzerland, were selected to ensuring the practicability and quality of the construction work. The earthquake unfortunately proved that local construction techniques and skill did not prevent houses from collapsing during the incident. This clearly indicated the urgent need to improve on both, construction technologies and especially on construction skill. For this reason the „Basic Construction Training Manual for Trainers“ has been developed by Skat in close cooperation with field based SEWA construction engineers to ensure that their needs and expectations are met. This Training Manual is the summary of basic practical con- struction know-how that is of crucial importance to transfer appropriate and new skills to local masons, supervisors and SEWA members in building earthquake resistant houses. It will help construction trainers to pass on relevant skills in constructing houses and improving infrastruc- ture in a practical manner, and offers a wide range of essential information. Beside the Swiss Red Cross and Swiss Solidarity supported Naya Ghar Project, this „Basic Con- struction Training Manual for Trainers“ will also serve other SEWA construction related projects. All partners actively involved in the creation and application of this Training Manual hope that trough it the new skills acquired by local masons, supervisors and SEWA members will lead to an better building standard and quality, preventing further loss of lives and property in this earthquake prone part of India. Peter Eppler Programme Coordinator Swiss Red Cross General Introduction When Gujarat has been hit by the horrifying earthquake in January 2001, international help for the reconstruction of houses and creation of livelihood was soon at hand and warmly welcomed by the needy one. The concerned government authorities and non-governmental organisations launched re- construction activities with an astonishing swiftness. The resulting focus of construction activities in Gujarat was demanding a huge number of skilled construction manpower that was regrettably not always easy at hand. This Basic Construction Training Manual for Trainers is tailor made for the specific capacity building / training needs of SEWA for the earthquake reconstruction programme that is, financed by the Swiss Solidarity Fond and implemented in partnership with Swiss Red Cross and technically coached by Skat_consulting. This manual is specifically focussing on the practical implementation level and provides a wide range of essential information as well as dos and don’ts for trainers to communicate to masons and supervisors during theoretical and on the job trainings. It also contains photos and sketches / drawings that add clarity to the context. These photos and sketches have been collected from various reference sources and are therefore, not of uniform character in its present form. This manual is divided into five separate modules. Module one explains the overall and essential parts of a building. Module two provides information about the quality benchmark and testing methods of building materials that are most commonly used in housing construc- tion in Gujarat. Module three describes the skilled working principles for; Mortar, Concreting, Brick masonry, Stone masonry, Curing, Plastering and Flooring. Module four describes essential working safety measures to avoid occupational accidents. And finally, Module five provides a list of literature where useful information regarding earthquake save house designing and construction principles are described. The merit of this manual lies in the modular structured documentation of information from a practitioner for practitioners that allows the design of various combination of required practical training. A very tiny fraction of active masons in Gujarat have received formal masonry training. Practical construction skill and information are transferred in an informal way. Because of this system, some practices that are actually wrong have now become “good practice standard” and therefore some present construction qualities are not up to professional quality standards in Gujarat. There is a genuine need and high demand for formal building construction training by masons. SEWA has recognised this as a high priority and expressed the necessity of professional and practical construction training material for their construction related programmes. This Basic Construction Training Manual for Trainers is the resulting outcome of their expression. 5 MODULE 1: Basic Building Parts .................................................................. 7 MODULE 1 MODULE 2: Building Material and Quality Standards .......................... 19 MODULE 2 MODULE 3: Principles of Construction .................................................... 33 MODULE 3 MODULE 4: Safety .......................................................................................... 83 MODULE 4 MODULE 5: Earthquake resistant construction practices .................. 89 MODULE 5 5 7 Basic Building Parts MODULE 1 Various parts of a building (Floor, wall, openings, roof, stair) 7 9 Basic Building Parts Content MODULE 1 1.

  • The Art of Stone Masonry in the Rockbridge County Area (1700 to Present)
    The Art of Stone Masonry In the Rockbridge County Area (1700 to present) Steven Connett Archaeology 377 5/25/83 Dr. McDaniel The art of stone masonry in the Shenandoah valley seems to be somewhat of a mystery prior to the nineteenth century. However, as some of us have learned from the anthropology 101 course: The absence of artifacts (documents in this case) is just as important as the presence of artifacts. In order to make sure that the lack of information was not due to my possible incompetence in research, I spoke with a current day stone masoner named Alvis Reynolds. Mr. Reynolds relayed t o me that when he was trying to learn the skills of stone masonry he, too, had great difficulty in obtaining information and thus decided to teach himself this art through the process of trial and error. Although this information did not directly aid me in my research, Mr. Reynolds did provide me with a bit of information that allowed me to derive a hypothesis on why there is this unusual lack of information in this line of study. I will state my hypothesis in this paper, however, I will not be able to prove it or disprove it due to the deficiency in available information. Mr. Reynolds explained to me that in the eighteenth century there were nomadic stone masoners. These nomadic workers went from valley to valley in search of people who needed help with building their houses. Since these people did not know how to cut stone themselves (after all, stone cutting is not the type of thing that is innate to most people) they had no choice but to p~y these men for their services or go unsheltered.

Martin & Associates, Inc. or the participants' organizations. Summary Rubble-stone masonry houses are still found throughout Slovenia. This housing type with its special history represents a typical, older residential building in the northwestern part of Slovenia. After their destruction during World War I, these houses were rebuilt, mostly with the recycled stone material from demolished buildings. Many houses of this type were subsequently damaged during the last two earthquakes in Slovenia (1976 Friuli and 1998 Bovec). In order to preserve the country's architectural heritage, about 66% of these houses were strengthened following these earthquakes. http://www.world-housing.net/whereport1view.php?id=100025 1. General Information Buildings of this construction type can be found in the area of Upper Posocje. The residential housing stock built before the World War II in that area is generally of this type.

Our consultant conservation architect Mr Ken Borthwick has written a detailed assessment of this proposed scheme and the paper is attached herewith for your consideration. In his assessment (which closely examines aspects of WSD's HIA) Mr Borthwick looks at the original positioning of Flagstaff House on the crest of the slope, as well as at what he assesses to be its original grounds based on historical plans and early pictures of Flagstaff House in the HIA. He has made an assessment of an historic, rubble stone, fortified defensive wall with loopholes for firing through, which he opines may be the earliest example of British military fortification surviving in Hong Kong and a vital piece of historic evidence. WSD's HIA totally fails to identify this feature for what it is, nor assess its historical and cultural importance.

  • Streatham and Streatham Hill Conservation Area Statement
    Streatham High Road and Streatham Hill conservation area statement Location 1The Streatham High Road & Streatham Hill Conservation Area is in the southern part of the London Borough of Lambeth. The Conservation Area stretches from Telford Avenue to the Streatham United Reform Church encompassing buildings on Streatham Hill (not including those already within the Leigham Court Estate CA31) and those that line the length of Streatham High Road. The Conservation Area includes the impressive length of commercial and purpose built residential apartment blocks dating from the late Victorian, Edwardian and inter-war eras and includes the Free Tate Library, the Police Station, St. Leonard’s Church, the Odeon and ABC Cinemas and other public buildings, which form an important centre for shopping, recreation and commerce. Origins of development and settlement Streatham High Road is one of London’s major arterial roads. From Roman times, and perhaps earlier, it has been an important highway running between London and the 2Weald. Traces of pre Christian burials were discovered when St. Leonard’s was rebuilt in the 19th century and demonstrate that this was a burial place over 2000 years ago. Also discovered were Roman masonry, coins and a Roman ditch. It is probably that the Romans built a military station on the site of St. Leonard’s consisting of a small fort enclosing 2 or three acres surrounded by an earthwork and a ditch. The derivation of the name “Streatham” being from the Saxon “Strat” Street and “Ham” Settlement. Streatham probably evolved as scattered settlements of Saxon farms along the two Roman roads, which ran through the area.

Second, there is a profound need to provide a technology for the safe reconstruction of owner-built rubble stone houses that is not dependent on high quality timber in areas where timber has been depleted or is too costly for many families to afford. The system proposed here, which has been invented and named “Gabion Bands” by Randolph Langenbach of Conservationtech Consulting, is intended to be an alternative means to meet the provisions of the National Building Code, but with a substitution of wire mesh (or polypropylene geogrid mesh) instead of the timber or reinforced concrete that are shown in the NBC for bands (ring beams) in the masonry walls of code compliant buildings.

  • Stone Masonry
    STONE MASONRY Definition: The art of building a structure in stone with any suitable masonry is called stone masonry. Types of Stone Masonry: Stone masonry may be broadly classified into the following two types: 1. Rubble Masonry 2. Ashlar Masonry 1. Rubble Masonry: The stone masonry in which either undressed or roughly dressed stone are laid in a suitable mortar is called rubble masonry. In this masonry the joints are not of uniform thickness. Rubble masonry is further sub-divided into the following three types: Random rubble masonry Squared rubble masonry Dry rubble masonry 1. Random rubble masonry: The rubble masonry in which either undressed or hammer dressed stones are used is called random rubble masonry. Further random rubble masonry is also divided into the following three types: a. Un coursed random rubble masonry: The random rubble masonry in which stones are laid without forming courses is known as un coursed random rubble masonry. This is the roughest and cheapest type of masonry and is of varying appearance. The stones used in this masonry are of different sizes and shapes. before lying, all projecting corners of stones are slightly knocked off. Vertical joints are not plumbed, joints are filled and flushed. Large stones are used at corners and at jambs to increase their strength. Once "through stone" is used for every square meter of the face area for joining faces and backing. Suitability: Used for construction of walls of low height in case of ordinary buildings. b. Coursed random rubble masonry: The random rubble masonry in which stones are laid in layers of equal height is called random rubble masonry.

Affiliated to RGPV & BU, Bhopal Tel: 7024368999, 9977995985|www.sistecgn.ac.in CONSTRUCTION OF SUPER STRUCTURE STONE AND ITS MAJOR TYPES BASED ON FORMATION • Building stone is a natural engineering material. • Stone is obtained from rock by applying certain disintegration techniques like manual quarrying and blasting etc. • Stones obtained from rocks are irregular in shape and size and thus need proper dressing before using for construction purpose. Based on formation of the parent rock it has three types 1. Igneous rock formed by the solidification of molten lava such as volcanic activity For example: Granite 2. Sedimentary formed from silt, marine life, and rocks that have been deposited by running water For example: Limestone, Sandstone 3. Metamorphic igneous or sedimentary rock that have been changed by pressure, heat, or moisture For example: Marble, Slate The stone masonry and its uses • Stone blocks laid with cement or lime mortar in a systematic manner forming a structural mass which can resist load without disintegration is called stone masonry. • Stone masonry is used for the construction of walls, foundation, columns, lintels, arches and other components of structures. • If abundantly available it can serve as an economical building material keeping in view the dressing cost and time of construction. • Undressed or rounded shape stone masonry with insufficient mortar is disastrous in earthquake hazard areas like Balakot, Abbottabad etc. Classification of stone masonry • Masonry can be classified according to the thickness of joints, continuity of courses and finish of face.
