摘要
本文主要论述斜向受力钢筋混凝土构件非线性性能的实验和理论研究工作。对所有试件在塑性区的长度和截面的曲率变化进行了测定,并编制可用于矩形及任意对称截面和考虑了混凝土非线性性能的计算机程序。六个试件的荷载-挠度理论曲线,表明计算和试验结果符合较好。此外,本文也讨论了斜向受力压弯构件的延性。
This paper discusses mainly the experimental and theoretcal studies on thenonlinear behavior of R.C. biaxial flexural-compression members. The actuallengths of plastic regions and the curvature changes of the sections of all the testmembers are measured and, taking account the nonlinear behavior of concretecomputer program which can be used in rectangular as well as arbitrary sym-metrical sections is worked out. The theoretical load-deflection curves of 6 testmembers show that the calculation results agree fairly well with the test ones.In addition, the ductility of the biaxial flexural-compression members is alsodiscussed.
