【摘要】 隔震技术是一种新型的抗震减灾技术,通过延长结构自振周期、增大阻尼来减少上部结构所受的水平地震作用。介绍隔震技术的基本概况和原理。以框架结构为例,计算并比较隔震前后的剪力,以及相对层间位移是否满足抗震要求。结果说明隔震技术能够降低结构各层在地震作用下的内力,保证结构的安全。更多还原

【Abstract】 Isolation technology is a new type of earthquake mitigation technology.It is by extending the natural vibration cycle,increasing the damping to reduce the level of the upper part of the structure when it suffered earthquake action.This paper mainly introduces the basic information of isolation technology and principle.Based on an example of frame structure,by setting isolation layer to calculate shear as well as checking whether the relative displacement can satisfy the seismic requirement in order to illustrate the isolation technology,reduce the structural layers under the action of internal forces in the earthquake and ensure the structural safety.更多还原
