中文摘要：

为了研究型钢混凝土异形柱框架角节点的抗震性能,进行了四个模型试件的低周反复荷载试验.结果表明,型钢混凝土异形柱框架角节点的滞回曲线饱满,抗震性能良好.在试验研究的基础上,通过有限元软件ABAQUS对试件进行了模拟分析,并与试验结果进行对比.二者符合较好.进而对承载力的影响因素进行了分析.结果表明：在一定范围内,轴向压力能提高试件的抗剪承载力;随着配钢率的增大,试件的抗剪承载力逐渐增大,在轴压比较小时,抗剪承载力增幅较大,当轴压比较大时,抗剪承载力增幅较小;水平荷载合力作用点的位置对试件的抗剪承载力影响较小.

英文摘要：

In order to study the seismic performance of corner joint in SRC（steel reinforced concrete） special-shaped column frame,tests were carried out on four specimens under low cyclic reversed loading.It is shown that load-displacement hysteretic curves of corner joint in SRC special-shaped column frame are plump.The joint has good seismic performance.Based on the experimental reasearch,finite element analysis software ABAQUS was used to simulate the properties of specimens and the calculating results proued consistent with those of the test.Further more,the factors affecting the shear capacity of specimens have been reasearched.Results show that the shear capacity of specimens increases with the axial compression ratio in certain extent and the steel ratio in core zone of the joint.The increase of shear capacity of the specimen with lower axial compression ratio is larger than the specimen with higher axial compression ratio.The position of horizontal load point has a minor effect on the shear capacity of specimens.
