| 摘 要： | 根据预应力混凝土梁斜截面开裂时的弯剪斜裂缝形态，分析了斜截面抗裂机理，在钢筋混凝土梁斜截面抗裂理论模式基础上，推导出预应力混凝土梁斜截面抗裂度的理论计算公式。经过合理简化分析，提出了预应力混凝土梁斜截面抗裂度的实用计算公式，并用大量试验资料进行了对比验证。

| Abstract: | Based on the analysis of the crack states and the mechanics of shear-cracking resistance,theoretical formulas are proposed for calcualting the shear-cracking strength of prestressed concrete beams,and a rational and simple formula is also proposed by simplifying the theortical formulas.These formulas are in good agreement with the large numbers of test data. |
