【摘要】 结构分灾抗震设计是基于性能抗震设计的一种实用设计方法。根据密肋壁板结构"砌块-框格-外框"分阶段释放地震能量的破坏模式,将分灾设计理论应用于结构的抗震设计之中,提出填充砌块作为结构的第一道分灾防线,框格作为结构的第二道分灾防线,而外框架及连接加强措施是结构体系的第三道防线的抗震分灾设计模型。以此为依据,对密肋壁板结构的三阶段分灾设计方法进行探讨。更多还原

【Abstract】 Damage-reduction seismic design is a practical design method of performance-based seismic design.According to damage mode of multi-ribbed slab structure which releases earthquake energy by stages,block-frame-outer frame,damage-reduction design theory is applied to structure seismic design.It is illustrated that damage-reduction seismic design model and three-stage damage-reduction design of multi-ribbed slab structure.Block which acts as damage-reduction member is served as first damage-reduction fortification line,frame which acts as damage-reduction minor structure is served as second fortification line,and outer frame and reinforced measure are served as third fortification line.更多还原
