［摘要］通过对一个附加角钢的预应力装配框架节点（试件ZPJD）和一个附加阻尼器的预应力装配框架节点（试件ZPZNJD）进行低周往复荷载试验，研究了试件ZPJD和试件ZPZNJD的裂缝分布、破坏形态、滞回曲线及位移延性等抗震性能。结果表明，预应力装配框架节点具有可观的耗能能力和较强的变形恢复能力，并且便于震后修复，结构整体具有良好的抗震性能，可在抗震设防区推广和应用。［关键词］预应力装配框架; 节点; 阻尼器; 抗震性能中图分类号：TU352.11 文献标识码：A 文章编号：1002-848X(2015)12-0058-03
Experimental study on the node of prestressed assembly frame with additional angle steels and dampersHan Jianqiang1,2, Pei Yahui1, Yang Na1, Xu Guoqiang1,2(1 College of Civil and Architectural Engineering, North China University of Science and Technology, Tangshan 063009, China; 2 Earthquake Engineering Research Center of Hebei Province, Tangshan 063009, China)Abstract: Based on low cyclic loading tests on the node of a prestressed assembly frame with additional angle steels (specimen ZPJD) and the node of a prestressed assembly frame with additional dampers (specimen ZPZNJD), seismic performances of two specimens were studied including crack distribution, failure pattern, hysteresis curve and displacement ductility. Results show that the node of the prestressed assembly frame, which has good seismic dissipation ability and deformation recovery ability, is easy to repair after the earthquake. The integrated structure has good seismic performance and can be popularized and applied in seismic precautionary zones.Keywords:prestressed assembly frame; node; damper; seismic performance
