摘要
Abstract
The seismic behavior of three types of joints ( bolted joint, welded joint and expanded section joint ) between a concrete frame and the added top steel stories was investigated under low cycle load reversals. Performance of the test specimens was evaluated in terms of failure mode, joint shear deformation, energy dissipation capacity and ductility, etc. The test results reveal that all joints fail due to concrete crushing and rupture of longitudinal bars as a result of plastic hinges formed at the fixed beam end. The performance of bolted and welded joints are favorable. The transfer steel plate has no visible deformation. The energy dissipation capacity of the increased section joint is better than that of the bolted and welded joints. The construction technique of bolted and welede joint are simple. The results in this paper are useful to the design and construction of steel adding stories on top of the concrete frame.关键词
