某教学楼抗震设计中软钢阻尼器的运用分析
|
摘要
现今已研发并应用于工程实际的阻尼器有多种形式,软钢阻尼器是较常见的一种。软钢是指硬度小、含碳量低的低碳钢,在进入塑性状态后具有良好的滞回特性,可以在弹塑性滞回变形过程中吸收大量地震能量。软钢阻尼器充分利用了软钢具有较好的屈服耗能性能和进入塑性阶段后良好的滞回特性。软钢阻尼器在实际结构振动控制中具有广泛的应用前景。本文以某学校的教学楼应用软钢阻尼器的减震设计为例,通过对结构进行弹塑性时程分析及对比应用软钢阻尼器的减震结构与非减震结构的抗震性能可知,应用了软钢阻尼器的减震结构具有良好的减震抗震效果,相比于非减震结构抗震性能有显著改善。
Today has been developed and applied to the engineering practice of damper has a variety of forms,mild steel damper is one of the more common.Mild steel is refers to the hardness of small,low carbon,low carbon steel,after enters the plastic state has good hysteretic characteristics,can be in the process of elastic-plastic deformation hysteresis absorbed a large amount of seismic energy.Take full advantage of the mild steel damper is mild steel with good yield and energy consumption after the inelastic phase good hysteretic characteristic.Mild steel dampers in actual structure vibration control has wide application prospect.Based on the application of mild steel damper damping to a school buildings design as an example,through the study on the elastic-plastic time history analysis of structures and compare the application of mild steel damper damping structure and the damping structure seismic performance,it shows that the shock absorbing structure of the soft steel damper has a good shock and shock effect,which has a significant improvement compared with the seismic performance of the non-damping structure.
