摘要
结合国内首栋预制装配整体式混凝土结构试验楼工程,对装配整体式叠合连续楼板进行现场加载试验研究。从内力重分布的角度,分析了叠合连续楼板在使用阶段的变形及受力特征。试验结果表明,装配整体式叠合连续楼板具有较好的整体工作性能;除具有单向叠合连续板的内力重分布特征外,还具有沿整体后浇层向周边板块内力调整的特点,具有一定的双向板受力特性。
Being related to the first assembled monolithic precast concrete testing-building in our country, the loading experimental study is introduced on assembled monolithic composite continuous slab. From the view of internal force redistribution, the displacement and intemal force of composite continuous slab in using times were analyzed~ The experiment result indicates that assembled monolithic composite continuous slab has well monolithic working performance. It not only have the internal force redistribution characteristic belong to unilateralist slab, but also have the characteristic of adjusting internal force to around area through monolithic casting layer. And there are some bidirectional loading performance in the slab.
