Research on Method of Performance-Based Seismic Design for Electric Apparatuses

摘要: 基于性能的抗震设计已成为国内外建筑抗震研究的热点问题。高压电气设备的抗震主要依据现行的抗震设计规范设计而成，但在地震作用下仍然会遭受巨大破坏,特别是灾后重建需要巨大投入。因此，提出了电气设备基于性能的抗震设计方法。阐述电气设备进行性能化抗震设计的必要性，给出了基于性能的电气设备抗震设计具体步骤及注意事项。根据抗震设计标准及电气设备的特点，在电气设备中提出变压器、电瓷型电气设备适于基于性能的抗震设计；同时还提出电气设备支架、减隔震装置也适用于基于性能抗震设计；最后提出将电气设备、支架及减隔震装置考虑为一个整体，进行一体化基于性能的抗震设计。

Abstract: Performance-based seismic design has been the hot issue of seismic design at home and abroad. The high-voltage electrical apparatuses are mainly based on the existing seismic design codes, but they are always subjected to huge damage under the strong earthquake. And this will lead to huge investments in the post disaster reconstruction. The performance-based seismic design for electrical equipment is proposed. The necessity of the electric equipment of performance-based seismic design is elaborated. Then the detailed procedure and matters needing attention of the performance-based seismic design for electrical equipments are provided. According to the seismic design standards and the characteristics of electrical equipments, electrical equipments including transformer and electric porcelain type electric equipments are suitable for performance-based seismic design; at the same time, electrical equipment brackets and isolation devices are also suitable for performance-based seismic design, and finally it is proposed that the bracket and isolation devices of the electrical equipment can be considered as a whole for the integration of performance-based seismic design.
