Experimental Study on Dynamic Response Characteristics of Steel Frame Incorporated With Lead Damper Into Beam Splice

This paper presen 窰 s an experimental s加 dy on new moment frame cDmections designed to restrict damage to specific connection elemcnts placed at the bottem flange of the beam ． Composite effects and damage to the concrete slab were addressed in these tests ． Composite action Ied to a roughly 98 ％ increase in initial elastic stiffness and 20％ increase in yield strength ． Mcanwhile ， the plastic strain at the specific connection elements was increas巳 d by only 20％， indicating thaUhe plastic rotation capacity of the connections was hardly affected by tho presence of the concrete slab ． And the feature ofthe design forcing the connection Io rotate about the top fiange was beneficial in reducing damage to Ihc ooncrete slab ．
