| Research Abstract |
In this paper, the elasto-plastic behavior of joint panels at the connection of rectangular steel column and two H-shaped beams with different depth are reported. Panel moment, equilibrium equation, elastic stiffness and shear strength of these panels are derived theoretically. And the tests of the joint panels are carried out. The specimens are cruciform subassemblages of the joint panels at the connection of rectangular steel column and two H-shaped beams with different depth. The parameters of these tests are difference of beam depth, axial force ratio and width-thickness ratio. The result are as follows.
(1) The formulas of panel moment, equilibrium equation and elastic stiffness are almost the same ones of the standard panel at the connection of column and two beams with same depth.
(2) The shear strength of those panel is derived theoretically, using plastic analysis. In this analysis, two collapse mechanism are considered. One is the mechanism in which panel is plastic, the other is the mechanism in which parts of panel, beam flange and beam web are plastic.
(3) The shear strength and collapse mechanism derived theoretically were good agreement with results of test.
