摘　　要：介绍了ABAQUS中embedded region和非节点连接有限元模拟钢筋混凝土构件的建模方法、求解思路和特点。对embedded region无法约束转动自由度的缺点给予了说明。通过3个算例的对比说明了两种方法的优缺点和非节点链接有限元方法在处理钢筋混凝土构件方面的优越性。The modeling methods, solution thoughts and features, which apply the embedded region and the non-nodal FEM in ABAQUS to simulate the reinforced concrete members, are introduced. The shortcoming of embedded region that it can＇ t restrict the rotation degree is expounded. The advantages and disadvantages of the embedded region and the non-nodal FEM are expounded through three examples. Meanwhile, it is indicated that the non-nodal FEM is advantageous in dealing with reinforced concrete members.
