| 摘 要： | 大容量机组空冷系统属电站生命线工程的重要组成部分,结构与设备的安全性直接影响电厂的正常生产。为了有效控制不同水准强度地震作用下结构及关键设备的破坏程度,在综合考虑结构及内部关键设备破坏造成的社会影响和经济损失等因素后,提出大容量机组空冷系统抗震性能化设计方法,明确相应的抗震性能目标和性能水准。空冷系统抗震性能化设计中通过合理的抗震构造措施,确保不同性能目标下结构的承载能力及延性需求,解决以生命安全为抗震设防唯一目标的单一抗震设防标准不够全面的设计弊端,从而减小震后经济损失。

| Abstract: | Support structure system of air cooled condenser is an important component of lifeline engineering for a power plant,the security of the support structure and auxiliary key equipment affects directly the normal operation of the power plant.In order to control the damage degree and reduce the socioeconomic losses that caused by the damage of structure and auxiliary equipment due to different intensity earthquake,performance-based seismic design method which takes account of the performance of structure and auxiliary key equipment is established.Meantime the seismic performance objectives,seismic performance levels,as well as the design method are recommended.By means of proper detail of seismic design,the structural bearing capacity and ductility of different performance objectives can be ensured.Performance-based seismic design method can solve the shortage of conventional seismic design method which just considers the life safety of the people,which can decrease the economic losses due to earthquake. |
