| 摘 要： | 针对钢管混凝土拱桥计算的实体-梁单元法,详细地推导了该法的弹塑性切线刚度矩阵,在此基础上编写了钢管混凝土拱桥考虑材料非线性的极限承载力计算程序SYCFST,该程序得到了算例试验模型拱的验证。从而证明该程序的编写是正确的。

| Abstract: | Based on the document1] advanced solid-beam element method for CFST arch bridge calculating,this paper deducted the elastic and plastic stiffness tangential matrix in detail,draw up calculating program SYCFST for ultimate bearing capacity of CFST arch bridge based on this,which was tested and verified by experimental model arch.Therefore,the program was also correct. |
