摘　　要：端榀实腹式门式刚架相对中间榀而言,受力较为复杂,端榀刚架承担两个平面方向的风荷载,同时还有抗风柱相连。由于抗风柱的边界条件相对灵活,通常由设计指定约束并对其进行相应设计,因此抗风柱对主刚架柱的作用不容忽视,尤其是设计成两端铰接时,抗风柱(此时被称为摇摆柱)的不利影响在设计过程中往往通过主刚架柱计算长度增大系数来体现,本文以常见位于低地震烈度区的无吊门式刚架作为研究对象,具有普遍性和代表性,主要探讨不同边界条件下的抗风柱对主刚架稳定设计的影响,对于工程设计具有一定的实际参考意义。Compared with the middle truss,the force of the rigid frame is more complex.The rigid frame of the end truss bears the wind load in two plane directions,and the wind resistance column is connected.Because the boundary conditions of the wind column is relatively flexible,and it is usually specified by the design constraints,so the effect of the wind column on the main column can not be ignored.Especially when it is designed with hinged ends,the adverse effects of wind resistant columns(referred to as swing columns at this time)are often reflected in the design process through the coefficient of increase in the effective length of the main rigid frame column.This article takes the common non hanging portal rigid frame located in low seismic intensity areas as the research object,which is universal and representative,mainly explores the impact of wind resistant columns under different boundary conditions on the stability design of the main rigid frame.It has certain practical reference significance for engineering design.
