摘要
本文依据25根部分预应力砼梁的抗剪试验结果,着重研究了预应力程度、剪跨比及无粘结力筋对梁斜截面抗裂能力的影响,在理论分析和试验研究的基础上,对斜截面抗裂能力提出了一个半理论半经验的计算公式,计算值与试验结果吻合较好。
Oa the basis of the test results of 25 P. P. C, beams with . unbonded tendons, this paper investigates the influence of the degree of prestress, shear span-depth ratio and unbonded tendons on the anti-cracking capacity of inclined section of beams. A formula is put forward by the analysis of the theory and the study of the test. The formula coincides well with the test results.
