Mechanical Analysis and Construction of Bidirectional and Multi-span Continuous Cable Truss-cable Net Structure

摘要

The bidirectional and multi-span continuous cable truss-cable net structure consist of cable truss, cable net and apart steel truss. This allows the construction of a lightweight, longer span structure compared with the steel structural system. The parking lot of Tianjin Toyota No. 1 automobile factory is the new type structure system which is composed of rectangular grids formed by orthogonal cable trusses in two directions while inside each of the rectangular grids is saddle-shaped cable net. The form rinding process is introduced in this paper. Nonlinear mechanic behavior and ultimate bearing capacity is analyzed. The results show that cable trusses as intercolumniation connection have enough vertical stiffness to bear vertical load and guarantee structure stable, and cable truss and cable net can cooperative with work. This paper also describes construction.
