摘　　要：根据 4个工字形截面拉 -弯 -剪复合受力构件抗剪试验结果 ,提出了该类构件斜截面抗裂性和抗剪强度的计算公式 ,计算值与实测值符合良好。所建议的计算公式可供设计和修改《铁路桥规》Based on the shear resistance test results of four specimens with 工 section of PC member subjected to axial tension bending and shear, the formulas for calculating the diagonal cracking and the shear strength of this kind of member are presented. The calculating values agree well with the experimental data. The calculating proposals are valuable in design and may be used for revising the “China Railway Bridge Code”.
