摘　　要：随着我国建筑工业化的蓬勃发展,住宅工业化的趋势更是逐渐显现,特别是21世纪以来我国城市化进程不断加快,且中心城市中的高楼建筑不断增加,这使得钢筋桁架楼承板结构的应用成了研究的热点。钢筋桁架楼承板结构相较于传统现浇式建筑方式,体现出了其在耐火、力学抗弯、抗剪等性能的优势,基于此,本研究对于钢筋桁架楼承板的耐火性能以及力学性能的研究发展和应用做出了分析和总结。With the vigorous development of China′s construction industrialization, the trend of housing industrialization is gradually emerging, especially since the 21st century, China′s urbanization process is accelerating, and the trend of high-rise buildings in central cities is increasing, which makes the application of reinforced truss floor bearing plate structure become a research hotspot. Compared with the traditional cast-in-place building method, the reinforced truss floor support plate structure reflects its advantages in fire resistance, mechanical bending and shear resistance. Based on this, this study studies the application progress of mechanical properties and fire resistance of steel truss floor decks, and makes corresponding analysis and summary.
