摘　　要：简要介绍了建筑物消能减震结构基于能力谱法的分析过程,给出了消能阻尼器的附加阻尼比计算式,并采用消能减震技术对某既有办公楼进行了抗震加固分析。结果表明,消能加固后能显著提高原结构的抗震性能,从而实现建筑物"中震下使用无害,大震下保证人身安全"的性能目标。This article briefly describes the analysis of the process based on the capacity spectrum method of the energy dissipation structure,and gives the calculation equation of the additional damping ratio of the energy dissipation damper,and analyzes the seismic rehabilitation of the existing office building with the use of the energy dissipation technology.The results prove that energy dissipation upgrade can significantly improve the performance of the original structure against the earthquake,and guarantee the safety performance aims of the building with the use to the medium-magnitude earthquake and no danger to the high-magnitude earthquake.
