[摘要] 既有试验表明装配式钢梁-预制柱（PSC）组合框架结构在中、高烈度地区具有良好的抗震性能，但不同的柱-基础连接形式对结构的抗震耗能能力影响有所不同。本文运用有限元分析软件OpenSee所提供的混凝土模型Concrete02、钢筋模型Steel02以及粘结-滑移命令Bond-SP01重点模拟了既有试验中以机械连接器和纵筋锚固两种预制柱-基础连接方式连接的预制混凝土柱-钢梁组合框架结构构件的滞回曲线。分析结果表明：本文提出的数值模拟分析方法能够较好地模拟出两种不同的柱-基础形式对整体框架在低周反复荷载作用下的不同性能，滞回环和峰值力与试验结果能够较好地吻合，并反映了一定的捏缩效应。该方法能够有效应用于装配式钢梁-预制柱组合框架抗震性能的数值模拟。

Abstract: According to the existed experiment, assembled steel beam and precast reinforced concrete column composite moment frames have well behavior in medium and high seismic regions. However the energy dissipation capacity would be influenced by different column-footing connection types. Finite element software OpenSees was used to build the models of column-footing connection by mechanical couplers and dowel anchorage. Numerical results indicate that analysis model based on OpenSees can reflect the differences in seismic behaviors of these two test subassemblies. The proposed numerical analysis can be successfully applied to stimulation of assembled steel beam and precast reinforced concrete column composite moment frames.

Keywords: OpenSees; PSC composite moment frame; numerical analysis
