Abstract:A simulation analysis method of temperature variation effect was introduced to solve the problems in the construction of Hangzhou Olympic Sports Center, including the basement expansion, complex concrete structural system of the upper stand, over-length structural shape and ambient temperature variation influence. The method considers comprehensively the optimization of concrete post-cast strip, the simulation of finite restraint stiffness of model bottom and the simulation of concrete creep and shrinkage effects. Combining with the feasible plan of construction schedule and feasible value of temperature loads in different stages, the simulation analysis method of temperature variation effect considers time effects and construction stages. Results show that the method can be applied in engineering design to reveal the temperature variation effect through the whole generative process of the concrete structure reasonably and effectively, and can help to find out the over-deformed or over-stressed structural components to propose the corresponding effective optimization suggestions and guide construction schedule and construction control.

Keywords:Hangzhou Olympic Sports Center; temperature variation effect; creep; shrinkage; construction simulation; finite stiffness
