| Abstract: | The steel roof for a large steel project is supported on several irregular steel columns.It has a complex model,large spans in two directions as well as long cantilevers.The universal finite element software(ANSYS) is used to analyze and trace the construction process.The appropriate mechanical models,analysis methods for the steel structure and simulation of erection procedures are proposed.According to the results,the most unfavorable positions and the best for temporary supporting systems during construction procedure are determined.The accurate numerical results and dynamic simulation are obtained for the structural construction. |
