SEISMIC EVALUATION OF REINFORCED CONCRETE BUILDING

In the study of evaluation for retrofitting of any building made up of reinforced concrete is done by using method of inelastic method, capacity curve method etc. Capacity curve which is load deformation plot is output of inelastic method. As this inelastic analysis is non linear static analysis, so load deformation curve is obtained from ANSYS. ANSYS which is based on finite element method is used for performing the non liner static inelastic analysis and cracking pattern can be analyzed in ANSYS. The need of retrofitting of any particular element of any existing building will be obtained by cracking pattern. In this first symmetrical building is analyzed on ANSYS for the procedure development as per ATC-40 then symmetric evaluation is done on unsymmetrical building designed for without considering seismic effect and then same building considering the seismic effect according to IS 1893:2002. These results then compared for suggestion for retrofitting of affected members.
