在非线性程序DRAIN-3DX中建立并实现了纤维梁柱后屈曲单元，以预测管状支板和门户的屈曲、后屈曲和迟滞行为。在这个单元中，材料非线性和几何非线性都被考虑在内。该单元用于模拟管状构件在循环荷载作用下的后屈曲和滞回响应。并对循环荷载作用下的x支撑框架进行了拟静力分析。预测的总体响应与现有的实验和其他分析结果吻合良好。ASME版权所有©2002
The fiber beam-column post-buckling element has been formulated and implemented in the non-linear program DRAIN-3DX to predict Buckling, Post-buckling and hysteresis behaviour of tubular Struts and Portals. In this element both material and geometric non-linearities are considered. The element is applied to simulate post buckling and hysteric response of tubular members subjected to cyclic loading. Also Psuedo-Static analysis of X-braced frame subjected to cyclic load has been perfomed. The predicted overall response matched well with the available experimental and other analytical results.Copyright © 2002 by ASME
