NON LINEAR ANALYSIS OF RCC BUILDING WITH AND WITHOUT SHEAR WALL MD SHARIB RAHMANI M.TECH (STRUCTURAL & FOUNDATION ENGINEERING) Department of Civil Engineering Al-FALAH UNIVERSITY, FARIDABAD INDIA. ---------------------------------------------------------------------***---------------------------------------------------------------------
Abstract - Although different procedures are possible, the
Non-linear static analysis (pushover analysis) was carried out for the frames and the frames were then compared with the push over curves. Displacement and Base shear is calculated from the curves and compared. The nonlinear analysis of a frame has become an important tool for the study of the concrete behavior including its load-deflection pattern and cracks pattern. It helps in the study of various characteristics of concrete member under different load conditions.
The static pushover analysis is becoming a popular tool for seismic performance evaluation of existing and new structures. The expectation is that the pushover analysis will provide adequate information on seismic demands imposed by the design ground motion on the structural system and its components. The purpose of the paper is to summarize the basic concepts on which the pushover analysis can be based, assess the accuracy of pushover predictions, identify conditions under which the pushover will provide adequate information and, perhaps more importantly, identify cases in which the pushover predictions will be inadequate or even misleading.
1.1 OBJECTIVE
non-linear static analysis, also known as the Pushover analysis, also known as collapse analysis is considered to be a convenient method for evaluating the performance. On this study, the method is used to evaluate the performance of RC plane frames. Reinforced concrete (RC) frame buildings are becoming increasingly common in urban India due to increase in population and safety in such situation is much more important.
1. To provide analysis of R.C.C Structural with or without shear wall. 2. To perform Linear Analysis and Non-Linear Analysis. 3. To study the performance of R.C.C structure with or without shear wall w.r.t. different parameters such as story drift, story displacement, base shear, shear force etc. 4. To study the hinge formation during the performance of concrete frame to verify strong column weak beam. 5. To determine the effect of earthquake on various parameters like fundamental, time period, storey drifts, lateral joint displacements, bending moments and shear force in beam and columns. 6. To study the hinge formation during the performance of concrete frame to verify strong column weak beam behaviour of the members. 7. To determine the performance point of R.C.C with shear wall and without shear wall concrete frame by capacity spectrum.
This paper deals with the non-linear analysis of an RCC frame and also the non-linear analysis of an RCC frame with shear walls at different levels. The main aim is to carry out the difference in the push-over curves of the RCC frames and to calculate the displacement in the frames. The analysis is carried out using ETABS software .Push-over the analysis is carried out using ETABS software .Push-over curves for both the frames are obtained and comparison is carried out.
1.2 Description of pushover analysis The non-linear static pushover procedure was originally formulated and suggested by two agencies namely, federal emergency management agency (FEMA) and applied technical council (ATC), under their seismic rehabilitation programs and guidelines. This is included in the documents FEMA-273 [4], FEMA-356 [2] and ATC-40 [32].

1.INTRODUCTION The major criteria now-a-days in designing RCC structures in seismic zones is control of lateral displacement resulting from lateral forces. In this thesis effort has been made to investigate the effect of Shear Wall position on lateral displacement and Base Shear in RCC Frames. RCC Frames withG+14 are considered with and without shear wall.
