摘　　要：传统的分析方法都是以竣工后的整体结构作为分析对象,将结构荷载一次性施加在结构上进行计算,计算时经常得到与实际情况不符的结果。阶段施工是一个特殊类型的非线性静力分析,本文利用阶段施工加载用来模拟管桁架结构在施工过程中的结构刚度、质量、荷载等不断变化的过程。得到了相应每施工阶段末的结构应力和变形,从而指导结构的施工,减少了大量的支撑架,大大降低了工程的措施费。Traditional methods of analysis are based on the overall structure as an analysis object,and under the action of one-time structural loads imposed on the structure,calculations often obtain inconsistent results with the actual situation.Phase of construction is a special type of nonlinear static analysis,this paper adopts stage of work load to simulate the tube truss structure in consideration of the structural stiffness of the construction process,weight,load and the ever-changing process.The paper gets the stress and deformation of each end of construction phase,thus to guide the construction of the structure,as a result,the number of load-bearing frames is reduced and the construction cost of the project decreases significantly.
