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。
The yield strength multiples method and the equivalent linearization method are used to study the design method of the energy dissipating and damping structure of the additional metal damper. The two methods are respectively used to calculate the optimal damping of the additional metal damper. Structure for quantitative analysis. The optimal damping quantity calculated by the two methods is added to the original structure for time-history analysis and its damping effect is studied. The displacement, velocity, plasticity ratio and the shear force value of the main structure are both reduced Small, indicating that the energy-absorbing damping structure obtained shock absorption effect is better than the original structure. The two methods for calculating the optimal damping quantity are all available for reference. The research results lay a foundation for the popularization and application of energy dissipation and damping technology.
