摘要
采用有限元法对带摇摆柱门式刚架的非线性性能进行了精确分析,考察了摇摆柱数量、柱脚刚度对门式刚架2阶效应的影响。结果表明,带摇摆柱门式刚架的非线性影响在设计时不能被完全忽略。
Using finite-element method, the nonlinear capability of portal frames with swing eolumns has been analyzed accurately, and has inspected the influence to second-order effect of swing columns quantity and foot stiff. The result shows that the nonlinear inttluence of thesse portal frames cannot be neglected by completely when the design.
