| Abstract: | The pre-stressed cable arch is independently taken and its numerical model is established to analyze the construction behaviors of the steel roof of Zhengzhou International Convention and Exhibition Center. The behaviors of structures before and alter pre-stressing are analyzed by ANSYS software. The characteristics of the internal forces of the steel arch-truss, struts and prestressed cable are also explored, which may be a reference for design and construction of projects. |
