【摘要】 分灾模式下的抗震设计是一种基于性能的抗震设计.根据新型耗能结构体系———密肋复合墙结构独特的构造特点,探讨该结构体系遵循的分灾抗震设计原则.运用双重结构的概念,解析了密肋结构三道抗震防线的组成,并从结构动力学方程出发,利用密肋结构三道防线的特点,分解结构刚度和阻尼,为实现结构的分灾控制设计提供依据.更多还原

【Abstract】 The earthquake-resistant design under damage-reduction mode is a kind of performance-based aseismatic design.The characteristics of a new energy-dissipation structure system called multi-ribbed composite wall structure show the structure system is subjected to the seismic design principle.Using the concept of dual structure,triple seismic fortification lines of multi-ribbed composite wall structure are analysed.Based on structure dynamics equation,in accordance with the composition of seismic fortification lines,the structural stiffness and damping are resolved to provide a basis for structural damage-reduction controlled design.更多还原
