摘　　要：为研究空间钢构架混凝土梁受弯性能,应用5根空间钢构架混凝土梁和1根普通钢筋混凝土梁进行了对比试验,分析了空间钢构架混凝土梁的弯矩-曲率关系。提出了空间钢构架混凝土梁非线性全过程分析模式,编制FORTRAN计算程序,对空间钢构架混凝土梁的弯矩-曲率关系进行了模拟分析,并与试验结果进行对比,计算结果与试验结果吻合良好,表明所提出的非线性全过程分析方法可以模拟空间钢构架混凝土梁的截面受力全过程。In order to study the flexural behavior of spatial steel frame concrete beams, the comparison experiment of 5 spatial steel frame concrete beams and 1 reinforced concrete beam were carried out, and the relationship of the bending moment and curvature was analyzed. The nonlinear full-range analysis model of spatial steel frame concrete beams was proposed, a computational program of FORTRAN language was written and the relationship between the bending moment and curvature of spatial steel frame concrete beam was stimulated and analyzed, which is also compared with the experiment results. The calculation results are in good agreement with experimental results, which indicates that the full-range analysis method proposed in this paper can simulate the section stress process of spatial steel frame concrete beams.
