隔震技术是指将地震与建筑结构进行隔离的一种动态抵抗方法。通常的做法是在建筑上部结构和基础之间设置隔震装置,这样不仅可以增加建筑物的固有周期,避免共振,还能对地震能量进行有效吸附,从而极大的降低了在地震过程中结构物的变形和加速度,减少和避免建筑物结构受到破坏。本文结合工作实际,从隔震技术的工艺原理出发,并结合实例,就隔震技术在既有框架结构加固中的应用进行了研究。
Seismic isolation technology is a kind of dynamic resistance method that separates the earthquake from the building structure. The usual practice is to install isolation devices between the superstructure and the foundation of the building so as to not only increase the natural period of the building and avoid resonance but also effectively absorb the seismic energy so as to greatly reduce the structure during the earthquake Deformation and acceleration of the objects reduce and avoid damage to the structure of the building. In this paper, combined with the actual work, starting from the process principle of the isolation technology, combined with examples, the application of the isolation technology in the existing frame structure reinforcement has been studied.
