压碎破坏 meaning in English
crushing failure
Examples
- At first , the experiment carried out by tianjin university has been analysed according to the " nonlinear balance trying calculation " method , and the values of yield load and ultimate load agree with the test result better , and the curve of bending moment - curvature , bending moment - deflection can agree with the results . the second , the simplified formula for evaluation the ultimate flexural capacity of cfrp strengthened rc members is presented according to the three probable failure modes ( compression failure ; cfrp rupture ; crushing of the concrete in compression before yielding of the reinforcing steel ) . it is applicable to both singly and doubly reinforced rectangular sections , as well as flanged sections
首先利用钢筋混凝土非线性平衡试算法对天津大学试验进行了理论分析，所得分析值与试验结果相比，加固梁的屈服荷载、极限荷载能够很好地吻合，弯矩曲率关系曲线及弯矩挠度关系曲线较为吻合；其次，为了满足实际工程的需要，根据碳纤维布加固构件可能发生的三种破坏形态(压区混凝土压碎破坏、碳纤维布拉断破坏以及受拉钢筋尚未屈服时压区混凝土已压碎破坏) ，区别三种钢筋混凝土构件截面形式(单筋矩形截面、双筋矩形截面、 t形截面) ，分别给出了碳纤维布加固混凝土构件抗弯承载力的简化计算公式和适用条件，并进一步探讨了这三种截面形式下进行加固设计和复核的步骤。
