徐礼华 李锦辉 (武汉大学土木建筑工程学院 430072)丁仕苗 (武汉大学设计研究总院 430072)[提要] 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,两者吻合较好。
[关键词] 钢纤维混凝土 叠合梁 非线性有限元分析 本构模型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.
