Richard 2013 iii ASSESSING THE PERFORMANCE OF STRUCTURAL BAMBOO COMPONENTS Michael J. Richard, Ph.D. University of Pittsburgh, 2013 Bamboo has been a traditional construction material in many regions for centuries. The rapid growth and maturation rate of bamboo as well as its good strength properties and global accessibility make it a promising non-conventional building material resource. However, due to limited standardization and design criteria, bamboo has often been relegated to non-engineered and marginally-engineered construction. The current study assesses the performance of full-culm structural bamboo components and appropriate standard material and member test methods. A brief overview is given to the motivation for the study of structural bamboo, placing the work in its social context, followed by background on the properties of bamboo and the structural applications of the material as well as the pathway to its further standardization and utilization.

  • Bamboo: Green Construction Material
    Bamboo: Green Construction Material Case Study Bamboo Bamboo: Green Construction Material New industrial application and modern construction design have both demonstrated bamboo’s huge potential. Key Regulatory Mechanisms putting restrictions on bamboo development. Messages Lack of awareness has been the bottleneck inhibiting bamboo from taking shape in construction. Focusing on modern technology and financial support can expand bamboo market in construction. Strengthening institutions and government scheme can proliferate bamboo use in construction. Case Study Bamboo EXECUTIVE SUMMARY Bamboo belongs to grass family and has been associated with various names such as “poor man’s timber”, “Green Gold”, “Cradle to Coffin” because of its various documented applications. Bamboo is widely recognized as highly renewable, fast growing, economic raw material. Products from bamboo are grouped into industrial use, food products, construction and structural application, wood substitutes and composites, and cottage and handicraft industry. Bamboo is most abundant in India. India has the huge potential for bamboo with 14 million hectares of bamboo forest area. India is the second largest country in terms of bamboo resources. The yield per hectare of bamboo in India is very low compared to China, Taiwan and Japan which contribute about 80% to the world’s bamboo market. In coming years India is expected to face timber shortage in order to meet the housing needs of the increasing population. Moreover, the increased dependency on conventional materials is held responsible for degradation of environment. Both the reasons have led to give a thought on the use of bamboo as a substitute for wood and steel as it is considered as highly renewable and environment friendly material.

Kassa April 2009 © 2009 Bewketu Z. Kassa ALL RIGHTS RESERVED ii COMMITTEE MEMBERSHIP TITLE: Bamboo: An Alternative Building Material for Urban Ethiopia AUTHER: Bewketu Z. Kassa DATE SUBMITTED: April 2009 COMMITTEE CHAIR: Arthur J. Chapman, Professor Architecture Department COMMITTEE MEMBER: Jens G. Pohl, PhD, Professor Graduate Coordinator Architecture Department COMMITTEE MEMBER: Howard Weisenthal, Professor Architecture Department COMMITTEE MEMBER: Jacob Feldman, Professor Architectural Engineering Department iii ABSTRACT Bamboo: An Alternative Building Material For Urban Ethiopia Bewketu Z. Kassa This project explores the potential of bamboo as an alternative building material for low cost housing units suitable for urban Ethiopia. The rational for the application of bamboo comes from its abundance throughout the country, and its proven physical properties that equate it to other building material like timber, steel and concrete. The proposed bamboo based design solution concentrates on simplification of construction methods, prefabrication of structural components and vertical densification of housing units, addressing the lack of skilled labor, cost of construction time and urban land respectively. An understanding of the design solution was established by constructing a full-scale section prototype and performing laboratory tests on key structural components. iv ACKNOWLEDGEMENT I would like to extend a special thank you to my Committee Chair Professor Art Chapman and Committee Members Dr. Jens Pohl, Professor Howard Weisenthal, Professor Jake Feldman for providing their valuable guidance throughout my project and graduate studies.

  • Bamboo As a Building Material
    International Journal of Civil Engineering Research. ISSN 2278-3652 Volume 5, Number 3 (2014), pp. 249-254 © Research India Publications http://www.ripublication.com/ijcer.htm Bamboo as a Building Material P. Sharma1, K. Dhanwantri2 and S. Mehta3 1,2,3Amity School of Architecture and Planning, Amity University Haryana Manesar, Gurgaon, Haryana, India. Abstract Bamboo is a renewable and versatile resource, characterized by high strength and low weight, and is easily worked using simple tools. It is widely recognized as one of the most important non-timber forest resources due to the high socio-economic benefits from bamboo based products. Bamboo is the world’s fastest growing woody plant. Bamboo grows three times faster than most other species. Housing is one of the priority items and sensing the current shortage of the dwelling units, the present administrative leaders around the world find tough to hit upon a solution for. Apart from the other substances already in practice, bamboo appears to be the most promising material. Bamboo building construction is characterized by a structural frame approach similar to that applied in traditional timber frame design and construction. In this case, the floor, the wall, the roof elements are all interconnected and often one dependent on the other for overall stability. The use of bamboo for foundation is rather restricted. This is mainly due to the fact that like timber when in contact with damp ground, they deteriorate and decay very quickly unless treated with some very effective preservatives. The most extensive use of bamboo in construction is for the walls and partitions.

  • Bamboo Structures for Modern Sustainable Architecture
    ISVS e-journal, Vol. 7, no.3, July, 2020 Bamboo Structures for Modern Sustainable Architecture Solanilla Medina Yor Maikol1, Shuvalov Vasily Maksimovich1, Bykova Galina Ivanovna1 and Sultanova Ainur2 1Department of Architecture, Academy of Engineering, RUDN University, Moscow, Russia 2Department of Rural Architecture, Moscow Architectural Institute (State Academy), Moscow, Russia Email: [email protected] Abstract Bamboo is an old and traditional building material throughout the world’s tropical and sub-tropical regions. Considered a renewable and versatile resource, bamboo has gained popularity over the years. Although not many architects use it as the main construction material in bearing structures, it is frequently highlighted in research. New technologies combined with innovated traditional techniques enable its use in structural applications in regions with a hot-humid climate. All this significant development is not only because of engineering advances, but also reckoning the capabilities of bamboo. Many specialists are developing new technologies, some of which are already used in construction. Bamboo fibers are longer and more flexible than wood, so they are often used in the construction of earthquake-resistant buildings. Innovations in the field of bamboo constructions allow us to expand the capabilities of this natural material, making it more stable in structures with large spans. This paper presents the case for promoting bamboo structures in the modern world. The paper uses the following research methods; study of literary and online sources, abstraction, analysis and comparison. It argues that in the 21st century, bamboo structures are becoming more in demand due to the increasing environmental problems in the cities. Natural origin, rapid production, construction and recycling of bamboo structures are very good reasons for promoting bamboo as a versatile material.

  • Bamboo, the Building Material of the Future!
    Bamboo, the building material of the future! An experimental research on glueless lamination of bamboo. Name: Coen Kampinga Studentnumber: 4037138 Studio: Architectural Engineering, TU Delft Place/date: Delft, June 12, 2015 1st tutor: Mo Smit 2nd tutor: Marcel Bilow 3rd tutor: Marcel Bilow External examinar: Dirk Dubbeling Figure 1 Bamboo pavilion concept (own illustration) ABSTRACT Bamboo, one of the most sustainable building materials we know today. Though, the market seems to be sceptical about its use for construc- tive elements. This might be explained by the fact that some structural standards still have to be proven. On the other hand cabinetmakers have already adopted (laminated) bamboo as a valuable material to make their products. These issues mainly apply to Western countries, whereas Eastern countries take a fundamental different approach. Bamboo is what they know as a material to make temporary structures or as a material for the poor, known as the ‘poor men’s timber’. Regarded as poor in the sense of poor quality on the one hand and affordable for the poor on the other. So, for bamboo to be accepted in Western countries we need to clarify technical data and comply with structural standards. In Eastern countries the challenge is to make people invent bamboo as a structural building material. As the history of laminated bamboo lumber traces back only 10-15 years, developments are still going on. Laminated lumber is known to make use of different layers of wood, glued and pressed together. The same principals have been applied to bamboo, which turned out to be a more labour intensive process regarding the assemblage of a multiplicity of strips.
