混凝土坡屋面结构设计优化分析

Optimization Analysis of Concrete Sloping Roof Structural Design

针对目前常见的混凝土坡屋面的建模计算方法展开讨论,提出不同的结构布置方案,并采用不同的计算软件PKPM和MIDAS GEN进行优化分析,比较计算结果的合理性.本文认为对于混凝土坡屋面,应采用空间有限元建模,同时减少折梁的布置,充分考虑折板的支撑的类支座作用.采取必要的构造加强措施,以折板形成坡屋面,可以减少工程量,具有很好的经济性,对于工程应用具有参考价值.

Calculation method of finite element model of common concrete sloping roof was discussed in this paper.Then, different structural layout schemes were proposed.And the optimization analysis results were compared from the perspective of structural rationality using different calculation software PKPM and MIDAS GEN.This paper recommended that for concrete sloping roof, space model should be used to calculate and sim-ultaneously reduce the layout of the poly-beams considering the kind of support function in folded slabs.It can have lower project amount through flap sloping roof with necessary structural measures to strengthen.It will have reference value for engineering projects because of favorable economy.
