摘要
为研究外套管式节点的抗震性能,进行3个十字形足尺构件的低周反复试验,并对主要试验数据进行分析总结;采用ANASYS有限元与试验结果进行对比分析。结果表明:分析模型与试验结果吻合较好。通过有限元模型分析结果和屈服线理论,确定加劲肋厚度和外套管厚度的设计方法。
In order to study the anti-seismic performance of out-shell connection（OSC） between cold-formed square tubular column and H-shaped steel beam,a quasi-static experiment under low-frequency cyclic load of cross-shaped specimens was designed and carried out,and main data acquired from the experiment was analyzed.With the software ANSYS,the finite element model of outer-shell connection（OSC） was built and its results were compared with test data.The comparsion shows that they fit well with test data.Based on the finite element model and yield-line theory,simplified design method of the rib stiffener and out shell was put forward.
