| Popis: | A new framework is presented for analysis of dynamic collapse behavior of steel frames using large‐scale parallel finite element method based on the domain decomposition method. The analysis software is based on ADVC as a part of the E‐Simulator that takes advantage of recent development of computer science and high‐performance parallel computing in computational mechanics. By making an analysis model with fine meshing, a complicated sequence of local buckling of columns and beams can be simulated. Numerical results are shown for dynamic collapse analysis of single‐story and 5‐story frame models to show that the global and local behaviors are simultaneously simulated by a high‐precision finite element analysis. Eigenvalue analysis is also carried out for a 31‐story frame to demonstrate that dynamic analysis can be carried out for a structure discretized to solid elements with more than 70 million DOFs.
