摘要

采用纤维模型法,用FORTRAN语言编制非线性数值计算程序,计算出矩形钢管膨胀混凝土梁在单向受弯作用下的荷载-变形全过程关系曲线。通过对8根矩形钢管膨胀混凝土梁的试验研究,考察了矩形钢管膨胀混凝土的纯弯力学性能。同时,将试验结果和理论分析计算的结果进行了对比,发现吻合较好。根据试验结果,确定了矩形钢管膨胀混凝土梁的极限承载力计算公式。最后,与其他形式的梁做了对比分析发现,矩形钢管混凝土梁的承载力、变形及材料利用率有明显的优势。
Numerical analysis program was developed,which was applied for the analysis of flexural behavior of expansive concrete-filled rectangular steel tube beam subjected to pure bending.And eight expansive concrete-filled rectangular steel tube beams subjected to pure bending were tested to investigate the pure flexural behavior in this paper.Compared with the experimental results,the analytical results are found to agree well with the former.According to the experimental results, the evaluation of flexural capacity under pure bending condition was suggested.At last,compared with other kind of beam, expansive concrete-filled rectangular steel tube beam has the advantage of bearing capacity,deformation and using date of materials.The results in this paper may be referenced in practiced engineering.
