【摘要】 采用屈服强度倍数法和等效线性化法研究附加金属阻尼器的消能减震结构的设计方法,用这两种方法分别计算结构附加金属阻尼器的优化阻尼量,对附加阻尼消能减震结构进行定量分析。将两种方法计算的优化阻尼量附加于原结构上进行时程分析并研究其减震效果,消能减震结构的位移、速度、塑性率及主结构承受的剪力值都有一定的减小,说明所得的消能减震结构的减震效果优于原结构。两种计算优化阻尼量的方法都有可参考性,研究结果为消能减震技术的推广使用打下基础。更多还原

【Abstract】 The methods of the multiple yield strength of structure and equivalent linearization were researched to discuss the design of energy dissipation structure.The optimal damping amount of structure with additional steel dampers was calculated by these two kinds of methods,and the quantitative analysis was done.The effect on the structure with the optimal damping amount which was calculated by these two methods was discussed.The values inculding the displacement,the speed,the plastic ratio and shear force of the main structure were less than the original structure.The results of both two methods can be referenced by designers,and it could be beneficial for the promotion of energy dissipation.更多还原
