摘要
本文根据最大主应力理论分析了轴拉力对拉扭构件抗裂度及裂缝倾角的影响规律，提出了拉扭构件抗裂度的计算公式并与试验结果进行了比较。公式概念明确，计算简便，与试验结果吻合良好。
Based on the maximum-tensik-stress criterion,the effects of axial tension on thecracking strength and the cracking angle of the tension-torsion members are analyzed.A formula for calculating the cracking strength is suggested and compared with the test results.The suggested formula has a clear concept,it is easy to be applied and in accord well with thetest results.
