摘要：This paper analytically investigates the temperature effects on modal parameters with the China National Aquatics Center. First, the temperature-induced variation of elasticity of modulus, temperature-induced inner force and temperature-induced variation of boundary conditions are regarded as the essential factors influencing on modal parameters. The contribution of above three factors to variation of modal parameters under both uniform and non-uniform temperature distribution is analyzed. It is concluded that temperature-induced inner force has larger contribution on variation of modal parameters than temperature-induced modulus of elasticity. The relationship between temperature and variation of modal parameters is different for uniform and non-uniform temperature distribution and some other valuable conclusions for space structure are given in this paper.
