集中荷载钢筋混凝土简支板受弯承载力试验研究

Experimental Study of Flexural Streugth of Reinforced Concrete Simply Supported Slabs under Concentrated Load

用塑性理论分析集中荷载作用下钢筋混凝土简支板的受弯承载力,研究了影响极限强度的主要参数。试验表明,本文所假定的机动位移场和计算的极限荷载值与试验值相符。研究认为,可用等效宽度的方法计算板的受弯承载力。

This paper studies the ultimate moment of resistance at yield lines of reinforced concrete slabs with two opposited simply supported edges under concentrated load as well as the principal parameters affecting the ultimate flexural strength of the slabs. The test shows that the postulated displaccment fields of collapse mechanism and the ultimate calculated load in this paper are in conformity with the test. The study shows that it is feasible to calculate the bending strength of the slabs with the equivalent width method.
