摘　　要：经对结构动力分析中传统的动位移模型研究后,建立了基于时空系的强迫约束下结构系统动力分析的理论框架.将物性变量的空间性和时间性同时考虑,给出了时空系中结构系统的定义方式,提出了两种动力修正的理论和方法,在此基础上推出了质量、阻尼和刚度矩阵及特征方程和平衡方程的动力修正模式,并通过耦合具有不同动力特性的子结构实施复杂结构的动力分析,直接输入地面运动实施结构抗震分析.After studying the traditional dynamic displacement model in structural dynamic analysis,a theoretical framework for dynamic analysis of structural systems under forced constraints is established based on space-time systems.Considering both the spatial and temporal characteristics of physical variables,two dynamic correction theories and methods are proposed.On this basis,mass,damping and stiffness matrices and dynamic correction modes of characteristic equation and equilibrium equation are given.Dynamic analysis of complex structures is implemented by coupling substructures with different dynamic characteristics.Seismic analysis of structures is carried out by directly inputting ground motion.
