前言在核电站及其设备的抗震设计中已经广泛使用1973年原子能委员会(今核管理委员会(NRC))管理指南1.60。此外,NRC设计反应谱在制订其他土木工程的抗震设计规程中已作为指导性材料使用。在“核电站抗震设计的设计反应谱”中及Newmark、Blume和Kapur(1973)早先发表的文章中给出了建立NRC设计谱的步 Foreword The 1973 Atomic Energy Commission (NRC) Administration Guide 1.60 has been widely used in the seismic design of nuclear power plants and their equipment. In addition, the NRC Design Response Spectrum has been used as a guideline in the development of other civil engineering seismic design codes. The steps to create an NRC design spectrum are given in “Design Response Spectrum for Aseismic Design of Nuclear Power Plants” and in earlier published articles by Newmark, Blume, and Kapur (1973)
