A saddle-shaped semi-rigid cable net structure

Abstract

The invention discloses a saddle-shaped semi-rigid cable net structure, comprising a beam string arranged in a positive force direction, a beam string arranged in a reverse force direction, and a boundary ring beam, wherein the upper chord rigid components of all positive beam string constitute a saddle-shaped concave surface, the upper chord cables of all reverse beam string constitute a saddle-shaped convex surface, the lower chord cables of all positive beam string and the lower chord rigid components of all reverse beam string constitute a concave elliptical parabola, and at the intersection, the positive beam string and the reverse beam string share a strut, the upper end of the strut is connected to the upper chord rigid component of the positive beam string, the lower end is connected to the lower chord rigid component of the reverse beam string, the lower chord rigid component of the reverse beam string is connected to the lower chord cable of the positive beam string, and the upper chord cable of the reverse beam string is connected to the upper chord rigid component of the positive beam string. The invention has good force-bearing performance and high force-bearing efficiency, and is easy to build.
