【摘要】 本文讨论了钢筋混凝土弯曲和压弯构件从开裂到破坏各个阶段的弯矩一曲率和荷载一位移关系。利用电子计算机方法对弯矩一曲率和荷载一位移曲线全过程作了理论分析,并与试验结果进行了比较,两者比较符合。根据107根试件的试验结果,归纳出钢筋混凝土构件在弯矩或弯矩和轴力联合作用下位移延性比的经验公式。更多还原

【Abstract】 This paper investigates the relationship between the moment-curvature and the load-displacement of flexural members and members under combined flexural and compressive axial load at the different levels from cracking up to failure.Theoretical analysis of the whole process of the moment-curvature and the load-displacement by the use of computer is compared with the results of the tests. The comparison shows a good agreement between them. According to the test results from 107 members, an empirical formula of the ductility ratio of the displacement for flexural members and for members under combined flexurai and compressive axial load is presented in the paper.更多还原
