摘　　要：通过分析主拱拱轴线、矢跨比、系杆刚度、截面形式等对结构受力的影响,以某厂房的拱形轻钢屋架为例,对屋架内力进行验算,分析了屋架上下弦杆内力变化规律,并提出增设支撑的加固方法。Through analysis the design parameters of arch axis,rise-span ratio,stiffness of tie bar and section forms, taking a light steel arched roof as an example,the internal forces on the roof and the changes of the internal force of to player haulm and bottom layer haulm was analyzed,and supporting strengthening method was proposed.
