摘要
本文以笔者所作50片部分预应力混凝土梁剪切破坏试验的结论以及其它试验者的试验结论为依据,分析讨论了公路桥规《JTJ023-85》中预应力混凝土梁斜截面抗剪强度计算公式存在的问题,提出一个具有改进意义的建议公式。与其它规范公式比较,建议公式的形式简单,适用方便,概念明确,精度能满足实用要求。
Based on findings from shear test results of 50 partially prestre-
ssed concrete beams tested by authors and the shear test results by others,
this paper discusses and analyses shear strength formula of prestressed
concrete beams in current《Highway Bridge Design Code JTJ023 85》in China.
The incompleteness of the shear strength formula is pointed out and an imp-
roved formula is proposed.Finally,the improved formula is compared with
that in《JTJ023-85 Code》and other code currently used both at home and
abroad.
