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\x0d\x0aet,1,solid65\x0d\x0akeyopt,1,7,1\x0d\x0amp,ex,1,3.15e10\x0d\x0amp,prxy,1,0.3tb,concr,1\x0d\x0atbdata,0.3,0.5,2.8,-1\x0d\x0amp,ex,2,2.1e11\x0d\x0amp,prxy,2,0.33\x0d\x0ar,1,1,0.00001,0,0,0.00001\x0d\x0armore,0,90,0,0,0,0,0\x0d\x0ar,2,2,0.0585,0,0,2,0.0585\x0d\x0a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！
