Abstract: Recently, a lot of over-long concrete structure can not be designed with movement joints in accordance with the structure specifications for the functionality of the building. By the influence of temperature and shrinkage, the structure will have some cracks, thus it will affect the use and durability of the building. This paper settled the analysis method of temperature and shrinkage stress in the view of a structural engineer and analyzed an over-long concrete structure in Guangzhou with the software of ETABS. Based on the analytical results, this paper proposed control measures to deal with temperature crack.
Key words: engineering structure; concrete structure; temperature stress; shrinkage influence; crack control
