Abstract

The seismic analysis and design of reinforced concrete (RC) frames is still an unresolved issue due to its complex behavior as the performance of RC building is linked to the features of the structural system, which have many influencing parameters. In this study, an attempt has been made to investigate the displacement scenario of RC residential building seismically located in Zone-V due to the influence of some basic parameters (column dimension, beam dimension, grade of concrete, floor height and seismic weight) in order to obtain a relation which could be used to estimate the expected lateral displacement owing to those selected parameters. In this study, a total of 297 RC buildings designed as per the Indian codal provisions [IS-1893-2002] were analyzed by linear static method using SAP2000 by varying selected and feasible input parameters chosen. The resulting displacements for the change of each parameter were obtained and finally a generalized equation relating the expected displacement as a function of those selected parameters was established using the regression method. The results of the comparison between the displacements obtained from analysis with that of the equation so formed shows that the proposed relation can be used directly to determine the expected displacement with high reliability.
