基于性能的抗震设计是结构抗震设计方法的一种发展趋势,是抗震设计理念上的一次变革。针对核电厂常规岛厂房这种特殊的工业建筑结构,基于性能抗震设计理念,提出了常规岛厂房的抗震性能目标、性能水准以及实施抗震性能设计的方法,并举工程实例说明如何应用这一理念,实践地证明了核电常规岛厂房采用基于性能抗震设计方法的可行性,可供同类工程设计时参考和采用。 Performance-based seismic design is a development trend of seismic design methods, which is a revolution in seismic design concept. Aiming at the special industrial building structure of conventional island plant of NPP, based on the concept of performance seismic design, the seismic performance target, performance level and the design of seismic performance of conventional island plant are put forward. The project example shows how to apply this concept, Practically proved the feasibility of adopting performance-based seismic design method in the conventional island plant of nuclear power plant, which can be used for reference and adoption of similar engineering design.
