摘要
在试验研究的基础上 ,通过分析叠合梁二次成型、二次受力的过程 ,考虑材料非线性 ,提出钢纤维混凝土叠合梁非线性有限元分析方法 ;运用C+ + 语言编制了钢纤维混凝土叠合梁从加载→开裂→破坏的全过程分析程序 ,经与试验结果对比 。
Nonlinear finite element program for steel fiber reinforced concrete (SFRC) composite beams is compiled with C ++ language, considering material nonlinear. By using the program, the nonlinear analysis for SFRC composite beam model from initial loading, cracking, yielding to failing is carried on calcuating the cracking, ultimate load and deflection. The calculated results correspond well to the experimental results.
