SUBSTRUCTURING ON-LINE TESTS ON STEEL BRACED FRAMES
|
´˜^i‰pjF
Earthquake response of braced frame with X-type braces was analyzed utilizing the substructuring technique. The brace frames analyzed were substructured into brace subassemblages and moment resistant frames. A realistic analytical model was used for the moment frames, while in pseudodynamic test of the brace subassemblages, a set of two push-pull tests on brace members was conducted using the on-line computer test control technique. Furthermore, to comfirm the advantage of braces made of high-strength steel, a parametrical analysis was performed with respect to slenderness ratio and load-carrying capacity ratio of braces.
