程浩德(福州大学土木工程学院,福州350108)[摘要] 通过2个不同剪拉比下的预应力混凝土扁梁框架内节点试件的低周反复荷载试验,对节点的破坏形态、滞回曲线、延性、耗能能力等抗震性能进行分析研究,并探讨剪拉比对预应力混凝土扁梁框架内节点抗震性能的影响。[关键词] 预应力混凝土;扁梁框架内节点;抗震性能;剪拉比中图分类号:TU375.4 文献标识码:A 文章编号:1002-848X(2012) S2-0317-03Effect of shear tension ratio on seismic behavior of inner joints of prestressed concrete flat-beam frameCheng Haode(Institute of Structural Engineering, Fuzhou University, Fuzhou 350108, China)Abstract: The pseudo-static test on two inner joints of pretressed concrete flat-beam frame have been camed out to research the seismic behavior, such as failure pattem, hysteresis curves, ductility and energy dissipation. And the effect of shear tension ratio on the seismic of inner joints of pretressed concrete flat-beam frame has been determined.Keywords: prestressed concrete; inner joint of flat-beam frame; seismic behavior; shear tension ratio
