Abstract

Abstract

A kind of two-end-linear-truss-string structure was studied, and the finite element models of circular-arc truss string structure and two-end-linear-truss-string structure with different end inclination angles were modelled. The difference of internal forces between the two structures was analyzed by the equivalent method of solid web section, and the steel consumption and mechanical properties of the two structures were compared through calculation and analysis under typical loads. The results showed that the steel consumption of the two-end-linear-truss-string structure with the optimal inclination angle of 60° could be saved by about 7% to 18% compared with the circular-arc truss string structure; the combined displacement of the two-end-linear-truss-string structure was larger, but less than the requirement in JGJ 257-2012 Technical Specification for Cable Structures; the maximum horizontal support reaction force could be reduced by 15% compared with another structure; the buckling modes of the two structures were similar, and the two-end-linear-truss-string structure had higher stability bearing capacity.
