| Description
| - The response of reinforced concrete structures subject to strong ground motion is associated with nonlinear behaviour. Pushover analysis has always been understood as a nonlinear capacity estimation tool and generally called capacity analysis. On the other hand, the standard concept of pushover method does not often provide solution which can be reliably compared with the rigorous procedure of nonlinear response history analysis. The most used and convenient methods for seismic calculation are based on response spectrum. The response spectrum gives an envelope of maximum load effects for given dynamic properties of the structure. Methods based on response spectrum are very appropriate for linear calculations. They give results comparable with time history analysis. Response spectrum methods cannot be used for non-linear calculations. This is because they are based on a linear combination of natural modes of vibration, which is not applicable for non-linear calculations. The pushover method uses non-linear material relations, but loads are based on linear assumptions. This is not appropriate for investigating the real behaviour of a structure under seismic loading. However, this method is appropriate for assessment of total load resisting capacity and for determination of dissipation properties. This can be used to estimate the coefficient of ductility. The new modified pushover method (NMPM) has been developed. The results obtained by this method are in appropriate accordance with the results obtained using nonlinear response history analysis. Seismic forces obtained from the modified method take into account both changes in modal characteristics of the structure and energy dissipation. Load effects were investigated in the stress and strain range both under the limit of design resistance and over this limit, where plastic behaviour is significant. Results are within 10% difference compared to direct integration.
