STRESS FIELD OF BASEMENT EXTERIOR PILASTER WALL CONSIDERING EFFECT OF TEMPERATURE AND SHRINKAGE

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 walls. The megabuttress 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 that the results of stress field analysis could not only be successfully applied to engineering examples shown in this paper,but also provide a reference for other projects.
