| 摘 要： | 二阶应力效应是指受压杆件在受力过程中轴向压力和变形的相互作用。在有侧移框架中,为了推导出简化并且实用的计算方法,应该在考虑影响二阶应力效应因素的基础上进行精确计算,然后根据计算结果归纳总结出简化公式。本文涉及的程序采用了非线性有限元方法,这种方法在考虑二阶效应影响的情况下可以计算结构内力和变形。根据计算,本文也总结了一些规律。

| Abstract: | The second-order effect is the interaction between the axial load and the deformation in an axially forced element.In sway frames,in order to have a brief and practical method,accurate calculation is needed,in which the factors that affect the second-order effect should be taken into consideration,and then practical calculation method can be generalized based on the accurate calculation.In this paper,nonlinear finite element program is used to calculate the inner force and deformation of the structure.Some regulations are summarized. |
