烟囱施工中提升桁架的内力分析

Internal Force Analysis for Hoist Truss in Chimney Construction

通过对烟囱施工中所用提升桁架所受荷状况及支承方式的分析，提出了提升桁架的力学模型，并且精确地分析了提升桁架的内力。

This paper analyzes the loaded state and the strut way of the hoist truss used in chimney construction and sets up a mechanics model of it.On this basis,this paper also analyzes the internal forces precisely and puts forward an improving proposal about the hoist truss's construction design.
