Precise Mechanics Behavior Analysis Method of Mega Members and Nodes in Steel Mega-Frame Structures

In this paper, a 4-node reduced integration shell element, which has high accuracy and computing efficiency, is adopted to simulate the mega members and nodes. A precise nonlinear response analysis method of steel mega members and nodes in steel mega-frame structures based on 3-D shell element model is given. The parallel computation technique in MSC.Marc is explored to the method to reduce the computing time. The reliability of the method and the efficiency of the parallel computation technique in reducing the computing time are checked by examples.
