Mechanical performance analysis of Steel Beam-Concrete Wall Rigid Joint

摘要

The beam-column joints play a key role in composite steel and concrete structures. In order to ensure a safe design of a new building and obtain optimum design, an experimental program consisting of the tests of three connections with different connection details under low-cyclic reversed loading, A series of mechanical performance such as the stress-strain relationship of steel beam web, beam flange, connecting plate, bracket web, bracket flange, distributing steel, concealed column in node core area are all analyzed, the results show that in the loading process, steel beam flange and web, bracket flange produced yield deformation, but the bracket web, distributing steel, concealed column didn't yield, so the steel beam flange and web, bracket flange must be strengthened in the design. The test results also show that the bracket can be regarded as canlitecver model in practical engineering.
