摘要
本文根据Ｌ形和Ｔ形截面钢筋混凝土压弯构件的试验结果，在证明了试件的横截面符合平截面假定之后，采用我国《混凝土结构设计规范》（ＧＢＪ１０—８９）的钢筋和混凝土的应力－应变关系，用数值积分法编制程序作非线性分析．由该程序所算得的构件承载力与试验的极限荷载有较好的符合。在此基础上提出了钢筋混凝土Ｔ形截面压弯构件正截面承载力的实用计算方法。
The results of an experimental and analytical investigation on the strength and deformation of biaxially loaded short and tied columns with L --shaped and T-- shaped cross sections are presented. The experiments explore that the deformations of the cross sections agree with the plane section assumption. For the purpose of nonlinear analysis, the numerical integral method is used for the computer program which is based on the steel and concrete stress --strain curves in GBJ 10 -- 89 Code of China. The theoretical predictions of the bearing capacities show good agreement with the experimental results. In this paper, a practical method is proposed for the determination of bearing capacity of T--shaped reinforced concrete members with fie-cure and axialforces.
