摘要
Abstract
Based on finite element method, a series of two-dimensional plane strain models of typical framework and underground station were built to study the influence of superstructure on infrastructure' s dynamic response with various ground motion inputs, spacing between constructions, stiffness and damping of subsoil, foundation buried depth and floor and stiffness of superstructure. Results show that earthquake wave exerts a tremendous influence. Interaction diminishes rapidly with the increasing of the structure gap when the damping of subsoil decreases and the foundation buried depth and floors' number of superstructure increases, interaction gradually augments. The effect of superstructure's stiffness on interaction is negligible.关键词
