[摘要]結(jié)合國內(nèi)首棟預(yù)制裝配整體式混凝土結(jié)構(gòu)試驗(yàn)樓工程,對裝配整體式疊合連續(xù)樓板進(jìn)行現(xiàn)場加載試驗(yàn)研究。從內(nèi)力重分布的角度,分析了疊合連續(xù)樓板在使用階段的變形及受力特征。試驗(yàn)結(jié)果表明,裝配整體式疊合連續(xù)樓板具有較好的整體工作性能;除具有單向疊合連續(xù)板的內(nèi)力重分布特征外,還具有沿整體后澆層向周邊板塊內(nèi)力調(diào)整的特點(diǎn),具有一定的雙向板受力特性。

Abstract: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 internal 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.
Keywords:precast concrete; composite continuous slab; internal force redistribution; monolithic casting layer
