Design and Behavioral Analysis of Multi storied RCC Moment Resisting Frame Using Linear Spectrum Analysis in Seismic Zone-IV of Indian Subcontinent

Abstract

In this paper seismic response of (G+15)R.C. framed building is analyses for seismic load case by using STAAD-Pro software as per IS1893:2002 part-1.This paper consider different seismic parameter like seismic zone(IV), response reduction factor(R), importance factor(I)& other parameters like rock/soil type, structure type, damping ratio etc. This paper provides complete guidelines for STAAD-Pro software analysis & STAAD –Pro gives the results after run analysis in the STAAD output viewer which shows joint displacements, support reactions, member forces, base shear and lateral load. If we consider the concrete era of construction activities, the land is scarce, especially in metro cities. Even though if there is the availability of land it may be in the sloping ground, hillocks, or on land-filled areas, in such areas, there will be difficulty in the construction and design aspects. To maintain the slope of the strata, different degrees of such buildings step back towards the slanting slope and may likewise also have set back simultaneously. Hence in the present paper, an attempt has been made to study, the G+15 storey building assumed to be on flat ground and also on sloping ground with a 20-degree inclination. The model is considered to be a soft storey with infill walls and two different shear wall arrangements. The building has been modeled and analyzed in STADD PRO software with the response spectrum method of analysis. The study reveals that a model with a shear wall improves the performance of the structure in terms of displacement, drift, and time period apart from the fact that the structure is being constructed in normal ground or sloping ground. STAADPRO is one of the finest tools for the design of structures. In this project, we analyzed the G+15 building through response spectrum analysis to develop the economic design. IS: 1893 (Part I) for seismic design is utilized to perform the dynamic analysis. The results show that multistoried buildings are generally stiff for earthquake excitation as the modal participation factor is more than 75 percent.
