摘要
本文应用屈服线理论对钢筋混凝土板的极限承载力进行了分析,推导出了在集中荷载作用下,两对边简支、两对边自由的板的承载力计算式,并考虑了荷载作用面积对承载力的影响;通过将荷载-挠度非线性曲线简化成二折线,建立了挠度的简化计算式。且计算结果与试验结果吻合较好。
Analysis of limit bearing capacity of reinforced concrete slab is conducted by the yield line theory in this paper. The formulas of bearing capacity of slab with two sides simple-supported and two sides free under concentrated load are deduced. The influences of load area oa bearing capacity are considered. Formula of deflection is given by nonlinear load-deflection curve simplified as a bilinear curve. Calculated results of the formulas above mentioned are proved good by test data.
