| Research Abstract |
In order to evaluate deformation capacity of moment connections until fracture for steel high-rise buildings subjected to long-period long-duration ground motion, a series of constant and varying amplitude cyclic loading tests were conducted. The effect of strength of connection, welding details and floor slab on deformation capacity were quantitatively indicated and the prediction method to estimate propagation of cracks was proposed to evaluate deformation capacity until fracture of connection. A method to strengthen moment connections by thick flange is proposed and its effectiveness is experimentally indicated
