摘要

压型钢板混凝土组合楼板是由混凝土与压型钢板组成且共同受力的一种楼板形式

具有施工便捷、受力合理、材料性能充分利用等优点。为了研究火灾条件下压型钢板混凝土组合楼板的承载机制以及破坏模式

采用ISO-834标准升温曲线

对2块压型钢板混凝土组合楼板进行了火灾条件下的试验研究

考察了组合楼板在火灾作用下板顶与板底的裂缝开展和分布情况

揭示了火灾下组合楼板的破坏模式

给出了楼板内部不同位置处的挠度—时间曲线、温度—时间曲线。通过对试验结果的对比分析

证明了受拉薄膜效应力是建筑火灾楼板体系的最终承载力。

Abstract

Steel deck-concrete composite slab is composed of concrete and steel deck

with its advantages

such as convenient construction

force reasonableness

and full use of material properties etc.In order to study the bearing mechanism and failure mode of steel deck concrete composite slabs under fire

the experimental study on two steel deck concrete composite slabs under fire is made

through adopting the IOS-834 standard heating up curve

to investigate the crack development and distribution of composite slabs at the top and bottom of the board.The failure mode of composite slabs under fire is revealed.The curve of deflection-time and the curve of temperature-time at different locations within the composite slabs are given in this paper.The tensioned membrane effect force is proved to be the final bearing force of the slab system under fire through contrastive analysis of test result.
