摘要
本文构造了既体现轴压力又体现侧向位移与轴向位移耦合因素的杆单元刚度方程,借助叠代逼近法处理非线性问题,综合杆件有限元分析的简便性与非线性分析方法的严密性,对受有水平和竖直均布载荷的单层与多层刚架稳定问题进行了研究,计算结果反映了多种因素对刚架力学响应的影响,得出有益的分析结论。
An equation of rod element stiffness embodying both axial compressive force and the coup- ling of lateral and displacements was formulated. With the aid of iterated approximate method for handling nonlinear problem and combining the handy finite element analysis of rod member with the strict non-linear analysis,the stability of single and multi-storey rigid frames bearing uniformly dis- tributed loads was effectively studied. The computed results reflected the effects of multiple factors on the mechanical response of rigid frames,from which a valuable conclusion ensued.
