ABSTRACT A Gated Community is a form of or containing strictly controlled entrances for pedestrians, bicycles and automobiles, and often characterized by closed perimeter of walls and fences. Gated community usually consist of small residential streets and includes various shared amenities. However there have been many different approaches in the design of gated communities. The design of a gated community with security and proper amenities is being preferred by the people. For smaller communities this may be only a or other . For larger communities. It may be possible for residents to stay within the community for most daily activities which is due to the amenities provided in the gated community. Such type of gated community is ideal for the many people. A gated community which with such amenities is designed.

The main steps of any and planning is drafting, analysing and designing the building. In the present days of improving science and technology, analysing and designing of a building has been made easy by using ETABS software. The building plan has been drafted using the AutoCAD software by the requirement and available area. The super structure i.e. the building frame has been analysed and designed using the ETABS software.

In this project, A G+10 building is considered to be analysed and designed for both gravity and lateral (wind and earth quake) loads as per Indian standards. By using the software building can be analysed and we can check for any failures in the analysis and redesign them, so that we can prevent failures after construction. By using the output building can be constructed according to the design.

Key words: Gated Community, Building, Wind and Earth quake, ETABS.

1. INTRODUCTION

In its modern form, a gated community (or walled community) is a form of residential community or housing estate containing strictly controlled entrances for pedestrians, bicycles, and automobiles, and often characterized by a closed perimeter of walls and fences. Similar walls and gates have separated quarters of some for centuries. The purpose of gates is not to deter or prevent crime but to provide the perception of security and exclusivity. Gated communities usually consist of small residential streets and include various shared amenities. For smaller communities, these amenities may include only a park or other common area. For larger communities, it may be possible for residents to stay within the community for most daily activities. Gated communities are a type of common interest development, but are distinct from intentional communities.

Some gated communities, usually called guard-gated communities, are staffed by private security guards and are often home to high-value properties, and/or are set up as retirement .ETABS is used to design the residential building in the gated community due to its advantages.

ETABS have set the international standards in structural analysis and design. They first took into consideration the characteristic properties of a building’s mathematical model, thereby allowing the graphical creation of a building’s model in the same sequence that will actually be constructed (slab by slab, floor by floor).

1.1 OBJECTIVES

The main objective of this study is to design a gated community and provide proper amenities based on the standards.

1)To analyze and design a G+10 residential building using ETABS software.

2)To design structural components like beam, slab, column and footing manually.

1.2 PRESENT STUDY

The present study is to design a gated community with G+10 residential which is according to the standards.

2. LITERATURE REVIEW

1) K.V.MANIKANTA (2016) Most of the work for analysis of multi-storey building has been done on STAAD Pro. Evaluation of forces and moments for Dead load, Live load and Seismic load considered. But there is very less work has been done using load combination.

2) M C Griffith and A V Pinto (2000) have investigated the specific details of a 4-story, 3-bay reinforced concrete frame test structure with unreinforced brick masonry (URM) infill walls with attention to their weaknesses with regards to seismic loading. The concrete frame was shown to be a “weak-column strong beam frame” which is likely to exhibit poor post yield hysteretic behaviour. The building was expected to have maximum lateral deformation capacities corresponding to about 2% lateral drift. The unreinforced masonry infill walls were likely to begin cracking at much smaller lateral drifts, of the order of 0.3%, and completely lost their load carrying ability by drifts of between 1% and 2%.

3) Poonam et al. (2012) Results of the numerical analysis showed that any storey, especially the first storey, must not be softer/weaker than the storeys above or below. Irregularity in mass distribution also contributes to the increased response of the buildings. The irregularities, if required to be provided, need to be provided by appropriate and extensive analysis and design processes,

4) Prashanth.P et al. (2012) investigated the behaviour of regular and irregular multi storey building structure in STAAD Pro. and ETABS. Analysis and design was done according to IS-456 and IS- 1893(2002) code. Also manually calculations were done to compare results. It was found that the ETABS gave the lesser steel area as that of STAAD Pro. Loading combinations were not considered in the analysis and influence of storey height on the structural behaviour was not described.

5) Kianand siahan (2001) have studied the use of outrigger and belt truss system for high-rise concrete buildings. The lateral displacement reduction related to the use of outrigger and belt system location in high rise concrete building subjected to wind or earthquake load. Eight 40-storey two dimensional models analysis using GT-Strudel for wind load and five 60storey three dimensional models analysis using ETABS for earthquake load. They have studied the maximum displacement reduction can be achieved by providing outrigger and belt system at different location.

6) Mohammed Abdul Rizwan et. al.,(2015) described the analysis and design of steel framed structure with Steel plate shear wall (SPSW). For this study, equivalent static seismic analysis and dynamic seismic (response spectrum) analysis is carried out for steel moment resisting building frame (G+6) located in seismic zone III. Mesh and strip method of modelling was used. The analysis was done in software staad.pro as per 1893:2002 and IS 800-2007. The different parameters considered for this study to compare the seismic performance of structure were displacement, axial force bending moment and maximum stresses.

To achieve the objectives of the study that is to design a gated community, which meets the basic requirements such as safety, durability, economy, aesthetic appearance, feasibility, practicability and acceptability. It has been proposed to follow the following methodology.

1)Site plan.

2)Structural planning.

3)Analysis and design using ETABS.

5 .CONCLUSION

Based upon the ETABS, the following conclusions are at the forefronts:

1) Maximum axial loads are observed for columns of interior part of structure compared to columns of outer portion.

2) Structure is analysed and designed for gravity loads and Lateral loads according to Indian Standard Codes provisions

3) All the structural elements are checked for displacement, maximum percentage of steel and drift, displacement , and storey shear for lateral loads.

4) Raft footing is designed in SAFE software for the building load exported from ETABS including load combinations.

5) Footing is also checked for Soil pressure, Displacement, Punching shear and Maximum percentage of steel.

6) The Gated community has become an important part of modern world and hence more importance should be given to create gated communities which are friendly to environment and which also utilize the modern technologies.

7) For the ever growing cities the construction of gated communities ensures the secured feeling and also due to the increased population, new gated communities are in demand. The site plan created based on standards with essential amenities is ideal for living.
