摘要
介绍了OpenSees程序中Nonlinear Beam Column单元、Displacement-Based Beam-Column单元和Beam With Hinges单元的计算原理;通过模拟一个钢筋混凝土柱构件,指出这三种非线性梁柱单元对于截面软化行为各自所具有的优势与不足。
The calculation principle of Nonlinear Beam Column element, Displacement-Based Beam-Column element and Beam with Hinges element of OpenSees are introduced in detail. The advantages and disad- vantages of the three nonlinear beam-column elements for section-softening behaviors are shown by a reinforced concrete column simulated.
