地震是古塔建筑破坏主要的自然灾害之一,现有的古塔建筑加固方法主要目的是提高古塔建筑抗震能力,从而避免地震带来的破坏,随着隔震技术的日趋完善与成熟,如何将隔震技术应用到古塔建筑抗震保护是我们文物保护工作者主要研究方向之一。本文在介绍了隔震原理与隔震技术的前提下,通过有限元软件模拟采用橡胶隔震支座的方法进行隔震加固,并对比了原结构与隔震结构的抗震性能,结果表明,隔震技术能够大大的提高古塔建筑的抗震性能。本文的研究成果对隔震技术在古塔建筑抗震加固中的应用起到一定的参考作用。
Earthquake is one of the major natural disasters that destroyed the ancient tower. The main purpose of the existing method of strengthening the ancient tower is to improve the seismic capacity of the ancient tower so as to avoid the damage caused by the earthquake. With the improvement and maturation of the seismic isolation technology, How to apply seismic isolation technology to ancient tower seismic protection is one of the main research directions of our heritage conservation workers. Based on the introduction of isolation principle and isolation technology, this paper simulates the use of rubber isolation bearings by means of finite element software for seismic isolation and reinforcement, and compares the seismic performance of the original structure with the isolation structure. The results show that, Seismic technology can greatly improve the anti-seismic performance of ancient tower buildings. The research results of this paper can be used as a reference for the application of the isolation technology in the seismic strengthening of the ancient tower.
