Analysis and Design of G+12 Storey Reinforced Concrete Building Using ETABS

Abstract

Extended Three Dimensional Analysis of Building Systems is abbreviated as ETABS. The significant objective of this program is to make multi-story structures in a purposeful way. The productive plan and development of quake safe designs is significant everywhere. ETABS was used to analyse and design a multi-story residential structure with the lateral loading effect of an earthquake. IS 1893-part2:2002 and IS 456:2000 were used to design this project. This analysis takes into account harsh earthquake zones, and reactions are evaluated using soil type-II conditions.

Introduction

I. INTRODUCTION

ETABS is perhaps the most popular design and analysis programme these days. This programme is mainly used by many organisations and firms to create project designs and analyse. As a result, the main focus of this article is on a comparison of the results produced from conventional and ETABS software analyses of a G+12 storied building structure.

The powerful elements of the designs, as well as the force, span, and recurrence content of existing ground movement, impact primary response to quakes. Primary investigation utilizing ETABS is the method involved with deciding the shape, size, coming about aspect and responses and specifying of the sturucture. The subsequent results of a construction so it can satisfy the reason for which it was planned and support the powers that will follow up on it for the entire of its lifetime.

The efficient design and construction of seismic events structures is crucial all over the world. According to India's geological data, tremors threaten around 54 percent of the country's area. This project uses ETABS programme software to design and analyze a multi-story G+12 structure with lateral seismic and wind load effects. IS 1893-part2:2002 and IS 456:2000 were used to design this project. This analysis takes into account various seismic zones based on its location, and reactions result is evaluated using type-II soil conditions. In this project, we're taking a zone-III plan. At Agra, the eathquake intensity is harsh, and the Zone Factor is 0.16. Ordinary RC moment-resisting frame is recommended for the structure, with a Response Reduction Factor(R) of 1.0.

In this research, the columns sizes vary from the ground to a particular upper stories, with the lower columns being larger than the upper column in order to minimize structural failure. The diaphragm is inflexible. To avoid possible eccentricity, the major beams lie on the columns. ETABS software is being used to compare the design and analysis of irregular and regular multi-story building configurations in diverse seismic zones. The special point at the focal point of a mass dissemination in space is known as the focal point of mass. The mean area of a mass dispersion in space is the focal point of mass

We planned the design in an affordable manner by limiting the size of the areas since this task manages its most financial sections strategy. Since the heap is more prominent at the base than at the top, there is little requirement for gigantic sizes at the top. By streamlining the segments by situating it in a more noteworthy ranges, longer course, how much bowing is brought down, and how much steel utilized is trimmed down.

C. Properties of Materials

In order to finish the task in ETABS programme, firstly we defines the material properties of concrete(in our case its M40) and material properties of rebars(i.e. HYSD500), sizes of beams and columns, thickness of slab, loads like live and super dead loads should also be defined, and seismic as well as wind factor will also be considered.

As like:

Concrete properties:     M40

Properties of steel:             HYSD500

Live load:                           2kN/m2

Beam size:                           300mm x 600mm

Column size:                       450mm x 600mm

IV. ACKNOWLEDGEMENT

We are highly thankful to Department of Civil Engineering, Galgotias College Of Engineering & Technology for providing the help for this work.

Conclusion

The following findings are drawn from the analysis and design of G+12 story buildings: 1) Our project entails the construction of an earthquake-resistant structure that is also cost-effective. 2) The previous dimensions of the beam and columns were B@300mmX600mm and C@300mmX600mm, respectively; however, after analysis, only the column fails. Thus the dimensions of column were altered to C@450mmX600mm, which is also more cost effective. 3) The seismic study was performed using ETABS software and personally confirmed according to IS 1893-2002. 4) In software analysis, the value of reaction force and loads increases gradually from to the roof top floor to the ground floor if we come down
