Static Mechanical Performance of Mega Steel Frame-Prestressed Composite Bracing Structure

Abstract:

Mega steel frame-prestressed composite bracing structure is a new kind of mega structure with a rigid-flexible composite bracing system composed of rigid Λ-shape steel brace and inverted Λ-shape flexible cable set up in the mega steel frame. By establishing the three-dimensional finite element model and considering the material and geometric nonlinearity, this paper analyzed the structural performance under whole process of static loading. The results indicate that the lateral deformation is mainly determined by horizontal load and the corresponding lateral deformation curve is bending type on the whole, whereas the deflection of mega beam is mainly governed by vertical load and pretension of cables.
