INCREMENTAL DYNAMIC ANALYSIS, EIGEN VALUE ANALYSIS & RESPONSE SPECTRUM ANALYSIS OF EXISTING RC FRAMED BUILDINGS BY USING SEISMOSTRUCT SOFTWARE

Rahul Diliprao Rakshe

Abstract


ABSTRACT

Civil Engineering structures are designed to withstand environmental forces like earthquake, along with gravity loads. These forces are random and dynamic in nature. Therefore the response of the structure is also dynamic and that is what causes the unsafe and uncomfortable conditions.

So, performance based analysis of the structure is required which can be achieved by Incremental Dynamic Analysis (IDA) as well as Response Spectrum analysis (RSA). But, Incremental dynamic analysis is quite accurate and actual response of the structure from the particular considered earthquake can be obtained by this method. An incremental dynamic analysis consists of performing a series of nonlinear dynamic analyses in which the intensity of the ground motion selected for the collapse investigation is incrementally or step by step increased until the global collapse capacity of the structure is reached.

In the present work, incremental dynamic analysis of reinforced concrete G+2, G+6, G+7, G+10 and G+11 building is carried out, In which G+2 Building used for Validation. IDA curves are developed with respect to peak ground acceleration. Performance stages of the buildings such as yielding and collapse are defined with respect to peak ground acceleration of the considered earthquake from the IDA curve. Building susceptibility that is whether the building can sustain the particular considered earthquake or not is found out using IDA. Also, serviceability criterion for inter-storey drift ratio from IS 1893:2002 is checked from the IDA.

Response spectrum analysis of both the G+6 and G+11 building is also carried out. From the Response spectrum analysis, graph of base Maximum Interstorey Drift Ratio to Storey is plotted& this graph is compared with IDA Maximum Interstorey Drift Ratio to Storey & with IS1893 (Part-1). Base shear capacity of both the buildings is also found out using IDA and compared with IS1893 (Part-1).
