|
摘要
利用大型有限元分析软件ABAQUS分析了T形截面钢骨混凝土柱在低周反复荷载作用下的受力性能,综合钢骨混凝土柱现有的试验研究成果,研究了T形截面钢骨混凝土柱在不同轴压比系数、配钢率、混凝土强度等级和长细比等参数对其延性的影响,得出了T形截面钢骨混凝土柱具有很好的延性性能,并提出了不同参数影响下T形截面钢骨混凝土柱满足一定延性要求的轴压比限值。
This article analyzes the mechanical performance of T shape section steel encased concrete column under low reversed cyclic loading based on the large finite element analysis software ABAQUS.Through the existing results of the study for the SRC column,The ductility performance of that influence is studied from different factors such as axial-load ratio,steel ratio,concrete strength grade and slenderness ratio.We get the conslusion that it has good ductility performance.Then the author put forward that it meet the ductility performance requirements of the axial compressive ratio limits under the influence of different parameters for T shape section steel encased concrete column.
