| 英文摘要 |
The objective of this study is to analyze the collapse of a reinforced concrete(RC) frame under seismic excitation using the vector form intrinsic finite element(VFIFE, V-5) analysis. In view of the preceding parallel researches, four major sets of queries to be addressed in this study are as follows:(1) the structural system model for mass points of the VFIFE method,(2) possibility that the motion behavior of space structure with large deformation and rotation from continuous states to discontinuous states can be analyzed by the VFIFE method,(3) the progressive failure of the structure components was investigated in detail by considering failure criteria of the modified Park & Ang’s damage index to model the element nodes of the cracking behavior, and(4) the material nonlinearity of elements adopted in the three-parameter model. Moreover, the comparison of the shake table experiments and the numerical simulation of V-5 method demonstrate the accuracy of this method. |
