摘要
在钢筋混凝土梁斜截面抗裂计算理论模式基础上,结合国内外大量试验研究资料、分析了截面高度、混凝土强度、纵向受拉钢筋配筋率、跨高比和剪跨比等因素对钢筋混凝土梁斜截面抗裂度的影响规律,提出了物理概念明确、形式简捷的集中荷载钢筋混凝土梁斜截面抗裂简化计算公式。
Based on the theoretical model, combined with the large number of test data, the effects of the depth of normal section,the concrete strength,the longitudinal reinforcement ratio .the shear-span to depth ratio and the span to depth ratio on the diagonal shear-cracking strength of reinforced concrete beams are analyzed .A rational and simple formula is proposed for calculating the shear-cracking strength of reinforced concrete beams subjected to concentrated load.
