【摘要】 对武昌火车站候车厅大跨钢—混凝土组合楼盖进行了分级实荷试验,实测各级荷载作用下关键构件的应变及挠度,以检验其承载力。试验结果表明,实测与理论分析结果基本一致,结构承载性能良好,为同类结构的设计应用提供了可靠的试验依据。更多还原

【Abstract】 Site classified loading tests,which measured the strains and deflections of key members,were completed to verify the vertical load-bearing capacity of the long-span steel-concrete composite floor slab for the waiting room at Wuchang Railway Station.The tests show that the measuring results are in good agreement with the finite analysis outputs and the slab has excellent structural load-bearing capacity,so that it can provide testing basis for the design of similar floor structures.更多还原
