可以用solid65单元建立钢筋混凝土的整体式模型,此时要分别定义混凝土和钢筋的实常数,给一个例子如下:/prep7 et,1,solid65 keyopt,1,7,1 mp,ex,1,3.15e10 mp,prxy,1,0.3tb,concr,1 tbdata,0.3,0.5,2.8,-1 mp,ex,2,2.1e11 mp,prxy,2,0.33 r,1,1,0.00001,0,0,0.00001 rmore,0,90,0,0,0,0,0 r,2,2,0.0585,0,0,2,0.0585 或者可以用solid65+link8,认为混凝土和钢筋粘结很好,如要考虑粘结和滑移,则可引入弹簧单元进行模拟,比较困难!
