摘要
为了研究型钢轻骨料混凝土组合柱的抗震性能,设计工字钢内嵌轻骨料混凝土柱的方式,通过有限元分析软件(Abaqus)分析剪跨比、轴压比对组合柱的抗震影响,得到轴压比为0.3以内,适当增加剪跨比可使延性系数增大,提高抗震性能的结果。
In order to study the seismic performance of steel lightweight aggregate concrete composite column, the design way of lightweight aggregate concrete column with embedded I-beam, through the finite element analysis software(Abaqus), the seimic effects of shear span ratio, axial compression ratio of composite columnsare analyzed.The result shows that within theaxial compression ratio of 0.3, the appropriate increase of the shear span ratio leads to an increased ductility coefficient and improves the seismic performance.
