高烈度地区黏滞阻尼器在框剪结构体系中的减震设计与抗震性能分析

Aseismic design of viscous damper for frame-shear structure system in high seismic intensity area

黏滞阻尼器是一种速度相关型耗能装置,其特点是能在不增加结构刚度的情况下耗散地震能量,从而在不增加结构总体输入能量的情况下减轻主体结构所受的地震力,达到保护主体结构的目的,在8度及以上的高烈度区结构有着广泛的应用前景。对于教学楼、医院等重点设防类的建筑,采用黏滞阻尼器进行减震设计是解决此类情况的一种很好的结构解决方案。本文通过设置黏滞阻尼器,提高附加阻尼比,很好地解决了工程抗震设计中的相关问题,并大大提高了结构的抗震安全可靠度。

The viscous damper is a speed-dependent energy dissipation device,which can dissipate seismic energy without increasing the stiffness of the structure,thus reducing the seismic force on the main structure without increasing the total input energy of the structure,and achieving the purpose of protecting the main structure,and it has wide application prospects in structures in high intensity areas with 8 degrees or more. For key fortified buildings such as teaching buildings and hospitals,it is a very good solution to adopt the viscous damper for a seismic design of similar structure. By installing the viscous damper and increasing the additional damping ratio,the relevant problems in engineering seismic design are well solved,and the seismic safety reliability of the structure is greatly improved.
