| Abstract: | Since the elastoplastic damages occur in concrete structures and components in plastic stage under a severe earthquake,precise prediction of nonlinear behavior of structures in the earthquake is important to assess the seismic safety of the structures.A structural elastoplastic analysis program MEASP which bases on macro elements is compiled with object oriented language and three kinds of nonlinear beam-column elements are implemented in MESAP: stiffness-based fiber element,flexibility-based fiber element ... |
