有腹筋预应力砼双向受弯构件抗剪强度的计算

Experimental Study on Shear Strength of Prestressed Concrete Members with Web Reinforcement Subjected to Biaxial Concentrated Loads

根据 1 0根集中荷载作用下有腹筋预应力砼双向受弯梁的试验研究 ,采用负工形梁法 ,推导出双弯构件斜截面抗剪承载力的计算方法 通过对本次试验的 1 0根试验梁及另外 2 0根试件的验证 。

Based on experimental study of ten prestressed concrete beams with web reinforcement ,the methods of negative I-shaped beams were adopted to calculate the shear strength of members with web reinforcement subjected to biaxial loads under biaxial bending.Having tested and verified the results of ten beams in this test and the results of the other twenty members,we found that the theoretical calculation was agreed well with the test results.
