Study on Temperature Effect of the Super-Long Concrete Structure in Electrolytic Aluminum Plants

Abstract:

Due to the demand of the architectural features and production processes, so that the structure can’t be constructed according to specification requirements to set corresponding expansion joints. This leads to the structure to form a super-long concrete structure. Such structures have large force and deformation under the action of temperature, and even cause cracking of the structure, which seriously impacts on the safe and proper use of structure. Further, if the structure is longer than the specification maximum spacing of joints, just relying on the qualitative construction measures to deal with the impact of the temperature effect on the structure can’t meet the requirements of structural design. Meanwhile, now the quantitative calculation of temperature effect isn’t unified at home and abroad，the adverse effect of the structural temperature effect is an urgent problem. In this paper, regarded the actual electrolytic aluminum plant long concrete structure as the research object, and used finite element analysis program to study the quantitative analysis to explore the laws of temperature stress and deformation size of the long concrete structure. It provides a reference for the construction and seamless design of future similar structure.
