The Theoretical Study on Temperature Effect of Super-length Concrete Structures and its Corresponding Engineering Measures

Abstract

The super-length concrete structure isn’t easily deformed under the action of temperature difference due to various constraints. It is easy to be cracked because of the excessive temperature stress. Based on the analysis of the characteristics of various types of constraints in the super length structure, and the finite element elasticity calculation of the specific engineering case, we analyze the internal relationship between the temperature effect characteristics and the constraint of the super-length residential structure. According to the formation mechanism of the temperature stress, some technical measures, which can reduce the temperature stress of the super-length structure, are put forward, and applied to engineering design as well. It verify the effectiveness of technical measures through the engineering practice.
