I. INTRODUCTION

Severe damage of buildings in the most distressing consequence of most natural hazards especially earthquake and due to ++. In the past limiting damage was not a prime objective of seismic design codes which concentrated only on providing an adequate level of life safety. Seismic load, wind load, dead load and live load is calculated and applied on structure. From these load combination maximum factor of safety is consider so the structure will not fail during natural hazards or due to overloading. Reinforced concrete special moment frames are used as part of seismic force-resisting systems in buildings that are designed to resist earthquakes. Beams, columns, and beam-column joints in moment frames are proportioned and detailed to resist flexural, axial, and shearing actions that result as a building sways through multiple displacement cycles during strong earthquake ground shaking. STAAD. Pro features a state-of-the-art user interface, visualization tools, powerful analysis and design engines with advanced finite element and dynamic analysis capabilities. From model generation, analysis and design to visualization and result verification. IS codes are used for manual calculations. For manual calculations of G+7 storey building construction limit state method is used. Therefore, it is need of time to analyze & design such hazard resisting structures so as to save human life and avoid property damage.

II. LITERATURE REVIEW

Prakash Sangamnerkar et al. (2015). Static and dynamic behaviour of reinforced concrete framed regular building. He has done the comparative study on the static and dynamic behavior of reinforced concrete framed regular building. Comparison of static and vibrant behaviour of a six storey‘s structure is considered in this paper and it is analysed by using computerized solution available in all four seismic zones i.e. II, III, IV and V. This is important for building design and resistant from earthquake. M. S. Aainawala et al. (2014). Comparative study of multi-storey R.C.C. Buildings with and without Shear Walls. He did the comparative study of multi-storey R.C.C. Buildings with and without Shear Walls. They applied the earthquake load to a building for G+12, G+25, G+38 located in zone II, zone III, zone IV and zone V for different cases of shear wall position. They calculated the lateral displacement and story drift in all the cases. It was observed that Multi-storeyed R.C.C. Buildings with shear wall is economical as compared to without shear wall. As per analysis, it was concluded that displacement at different level in multi-storeyed building with shear wall is comparatively lesser as compared to R.C.C. building

P. Rajaram, A. Murugesan, G.S. Thirugnanam (2010).Experimental study and research on behavior of interior RC beam column joint subjected to cyclic loading. He discuss about Experimental study and research on behavior of interior RC beam column joint subjected to cyclic loading is carried. Beam column joint is an important component of reinforced concrete moment resisting frames and should be designed and detailed properly, especially when the frame is subjected to earthquake loading. Failure of beam column joints during earthquake is governed by bond and shear failure mechanism which are brittle in nature. Therefore, a current international code gives high importance to provide adequate anchorage to longitudinal bars and confinement of core concrete in resisting shear.codes provide for reduction of seismic forces thorough provisions of special ductility requirements. Details for achieving ductility in reinforced concrete structure are given in IS 13920:-1993. This paper covers the analysis and design of two bay five stories R.C.C moment resisting frames for general building using ETABS as per IS 1893-2002 code procedures and detailed as IS 13920-1993 recommendations. Mohit Sharma et. al. (2015). To study the dynamic analysis of multi-storey Building. He considered a G+30 storied regular reinforced concrete framed building. Dynamic analysis of multi-storey Building was carried out. These buildings have the plan area of 25m x 45m with a storey height 3.6m each and depth of foundation is 2.4 m. & total height of chosen building including depth of foundation is 114 m. The static and dynamic analysis has done on computer with the help of STAAD-Pro software using the parameters for the design as per the IS-1893- 2002-Part-1 for the zones- 2 and 3. It was concluded that not much difference in the values of Axial Forces as obtained by static and dynamic analysis. Anwaruddin M. et. al. Carried out the study on non-linear Static Pushover Analysis of G plus 3 medium rise reinforced cement concrete structure with and without vertical irregularity. It was seen that irregularity in height of the building reduces the performance point of structure. There was reduction in displacement or deformation of the RCC building also.

This project is mainly based on software and it is essential to know the details about these software‘s 1. Staad pro(v8i)

4. ESTIMATION AND COSTING STAAD

(Staad stands for structural analysis and design) 1. Staad is the powerful design software licensed by bentley. Staad stands for structural analysis and design 2. To calculate S.F.D and B.M.D of complex loading beam it takes about an hour. 3. So when it comes up to building with several members it will take a week. 4. Staad pro is a very powerful tool which it does this job in just an hour staad is a best alternative for high rise buildings. 5. Now a days most of the high rise buildings are designed by staad which makes a compulsion for a civil engineer to know about this software.

AUTO CAD

Auto cad is powerful software licensed by auto desk company and cad stand for computer aided design. 1. It is used for drawing different layouts, elevations, details, sections different sections can be shown in auto cad. 2. We used for drawing the plan of multi stored building. 3. It is very useful for civil, mechanical, and also electrical engineer.

CONCLUSIONS:

The design of slab, beam, column, rectangular footing and staircase are done in limit state method which is safe at control of deflection and in all aspects Using staad.pro software, the design consideration has been taken as per the is codes. The design is safe in all conditions On comparison with drawing, manual design and the geometrical model using staad.pro the area of AST required for the beam, column, footing and slab are comparatively similar to that of the requirement. While software also gives required sizes of bar and members but with factor of safety. Auto-cad plan gives detailed information of the structure member‘s length, height, depth, count etc. After running model in Revit software it gives more plan details and various design options. This software gives more decorative building structure. STAAD PRO has the capability to calculate the reinforcement needed for any concrete section. The program contains a number of parameters which are designed as per IS: 456(2000). Beams are designed for flexure, shear and torsion. From the STAAD PRO result required different types, size and number of bars are found.

And final evaluation and valuation is confirmed by estimation and costing software.

Due to manual and software calculations, the required amount and material will be minimized so the structure comes under healthy for environment and safe for human beings.
