摘　　要：通过两榀大跨度预应力次梁楼盖结构体系组合构件的反复水平加载试验,分析研究了大跨度预应力次梁楼盖结构体系的受力特性。着重讨论了边主梁的扭矩折减系数以及考虑边主梁的作用对柱端弯矩增大系数的取值影响进行了讨论,并就设计中如何进行考虑给出了建议。By means of reversed cyclic loading tests on the specimens of long-span floor beams system,it was analyzed the behavior of long-span floor beams system during the tests.it was discussed the method of designing the spandrel beams properly,including the reduction of spandrel-beam-torque and the flexural strength ratio between columns and beams,and some applicable suggestions were also given.

关 键 词：边主梁 次扭矩 扭矩折减系数 柱端弯矩增大系数
