摘　　要：本文针对西部机电科技商务中心钢结构工程,采用一种新型无粘结耗能钢支撑,设计了消能减震结构,给出了支撑屈服力取值的设计建议,并进行弹塑性地震时程响应分析。分析结果表明,设计结果符合要求,且可减小地震响应。This paper presents the vibration control method of Western Machine Technology Business Centre in Xi'an which use a new type of energy dissipation device named unbonded brace (UBB). A design procedure based on the nonlinear time history analysis is proposed where the main parameter, yield force, is recommended. The analysis results indicate that the parameters obtained with the new design method are more valuable to use in the design and the response of structure can be significantly reduced with the installation of UBB.
