| 摘 要： | 通过19片模型梁的试验,研究了以粗钢筋配筋的先张法预应力混凝土梁的斜截面抗剪强度.观测分析了剪跨比、配箍率、预应力度等因素,对斜截面开裂载荷和抗剪强度的影响,介绍了试验取得的一批颇有价值的试验资料,及在此基础上提出的一个反映试验数据规律的计算表达式.

| Abstract: | This paper, based on the test of 19 model beams, reveals the research on shear strength in inclined section of pretensioned prestressed beams with bars. An analysis on the basis of observation is given to the cracking load and shear strength affected by factors such as shear span-depth ratio, web reinforcement index and degree of prestressing. A number of valuable test data and a caculating expression deduced from the data are also presented. |
