摘要
为研究偏心放大式减震方案的减震效果,以实际工程为例,采用有限元软件ETABS建模,通过对比楼层位移、位移角、楼层剪力和加速度等指标,进行偏心放大式减震方案与BRB方案的分析,得出结论:偏心放大式减震方案可充分发挥偏心支撑中耗能梁段和放大式阻尼器的作用,起到较好的减震效果;偏心放大式减震方案对变形的控制相对有限,效果弱于BRB方案,但其可有效降低楼层剪力,保护主体结构,加速度响应控制较好,可有效减少结构附属构件的损坏。
In order to study the damping effect of the eccentric magnified damping scheme,taking an actual project as an example,finite element software ETABS was used for modeling.By comparing the indicators of floor displacement,displacement Angle,floor shear force and acceleration,the eccentrically amplified damping scheme and THE BRB scheme are analyzed.The conclusions are as follows:the eccentrically amplified damping scheme can give full play to the role of the energy dissipation beam and the amplified damper in the eccentrically braced support,and play a better damping effect;The eccentric magnification damping scheme has relatively limited control over deformation and is weaker than the BRB scheme,but it can effectively reduce floor shear and protect the main structure.At the same time,the acceleration response is better controlled,which can effectively reduce structural attachments.Damage to components.
