摘　　要：本文对3块压型钢板-混凝土简支组合楼板进行了恒载条件下的火灾试验研究。对组合楼板的抗火性能与火灾行为进行了研究,考虑了组合楼板的跨度与抗剪连接件对简支组合楼板耐火极限的影响。试验结果表明:简支组合楼板的抗火性能较差,3块板的耐火极限均在30min左右;板的跨度对耐火极限的影响很大,而抗剪件的影响相对较小。The behaviors of three simply supported profiled sheet-concrete slabs with dead load were studied in fire experiments. The fire resistance capability and the response of the composite slabs subjected to fire were investigated, and the effects of different spans and anti-fire sheer members on fire resistance of simply supported slabs were studied at the same time. The experimental results show that the fire resistance capability of simply supported slabs is bad and the fire resistance is all around 30 minutes. It is also shown that the effect of different spans on fire resistance is primary, whereas the effect of anti-fire members is comparatively lesser.
