摘　　要：介绍了 4榀 8m× 6m大跨度次梁楼盖的大比例模型试验 ,主要研究预应力次梁在有无现浇板的情况下在边主梁中引起的约束扭矩以及该约束扭矩与荷载的比例在各受力阶段随次梁抗弯刚度和主梁抗扭刚度的改变而不断变化的规律 。The test of four large scale specimens of floor system with P.C. long-span beams is introduced.The restraining torsional moment of spandrel beams caused by P.C. beams with or without slab is focused on,along with change of the load-torque relationship affected by the beams' bending rigidity and the spandrel beams' torsional rigidity under different load level. The result presents important reference to the revision of national design standard and structural design.
