本文以我院試驗的37根梁及国外研究者280根梁的試驗资料为基础进行分析,得出了适用于均布荷載及各种集中荷載情况下鋼筋混凝土简支梁沿斜截面破損时承载能力的計算方法。用这个方法还可以确定出斜裂缝的水平投影长度、破損点位置及斜截面的破損型态。 In this paper, based on the test data of 270 beams of 37 beams and foreign researchers tested in our institute, the results are obtained. The results show that the reinforced concrete simply supported beam subjected to oblique section damage under uniform load and various concentrated loads Computation method. With this method, it is also possible to determine the horizontal projection length of the oblique crack, the location of the break point, and the type of breakage of the oblique section.
