Abstract:Finite element analysis software SAP2000 was used to analyze the stress and deformation of steel-reinforced concrete open-web truss and its brace system during the construction of Huaibei Mining Office Center Building. The results can accurately reflect the structure deformation and inner force distribution under the construction loads in every construction stage. It indicates that the arch-truss braced system is verified reasonable， which can provide theoretical basis for the construction scheme and real-time monitoring.

Keywords:construction simulation; open-web truss; connected structure; steel-reinforced concrete
