| Description
| - The New Modified Pushover method (NMPM) has used the fiber model for the nonlinear modeling, which represents distributed plasticity model, where cross section of the structural element is subdivided into concrete fibers and steel fibers. 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 linear combination of eigenshapes, which is not applicable for non-linear calculations. The pushover method uses non-linear material relations, but loads are based on linear assumptions is not appropriate for investigating real behavior of structure under seismic loading. However, this method is appropriate for assesment of total load resisting capacity and for determination of dissipation properties. This can be used to estimate the coefficient of ductility. The New Modified method of the pushover analysis has been developed as part of the research. Results obtained by this method are in appropriate accordance with results obtained by nonlinear response history analysis. Seismic forces obtained by 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 behavior is significant. Results are within 10 % difference compared to direct integration.
