摘要
考虑温度和收缩作用,采用ABAQUS有限元软件对同样厚度的带和不带扶壁柱的板墙以及设置后浇带的板墙分别进行应力场分析。分析结果表明:不带扶壁柱的板墙,不同分段长度板墙最大应力影响区域有明显区别;带扶壁柱的混凝土板墙,温度及收缩引起的应力主要与扶壁柱的设置间距有关,板墙分段长度对温度及收缩应力影响不大。巨型扶壁柱对板墙来说,起到了后浇带的一部分作用,对温度以及收缩引起的裂缝控制比较有利。分析结果不仅成功应用于背景工程,也可为相关工程提供借鉴。
Considering effects of temperature and shrinkage, the stress field analysis of the basement exterior pilaster wall with and without buttress columns and wall with post-castiag strips was done by the finite element method （ABAQUS）. The results showed that the stress induced by temperature and shrinkage actions in a concrete pilaster wall were closely related to the distance between buttress columns instead of the length of section wails. The mega- buttress columns that played part of the role of post-casting strips, had a positive impact on the crack control resulted from temperature and shrinkage actions. It was concluded successfully applied to engineering examples shown in this that the results of stress field analysis could not only be paper, but also provide a reference for other projects.
