| Research Abstract |
Two typed of ductile seismic retrofitting measures of existing steel building structures are experimentally studied: (i) A post-installed ductile knee brace member, which furnishes a shear-yielding device, is newly proposed. The mechanical performance of the knee brace member is experimentally investigated. The analytical model of the knee brace member are also proposed. (ii) An efficient stiffener placement for improving ductility of structural members are experimentally studied by exhaustive stub column tests.
