钢筋混凝土框架结构抗震加固方法浅述

Reinforced concrete frame structure shallow seismic reinforcement method described

地震灾害是常见的一种突发性和毁灭性自然灾害。由于地震对国家财产及人类生命的威胁越来越大,建筑物的抗震加固工作显得越来越重要。本文主要叙述了抗震加固工作的必要性,回顾了我国抗震加固工作的发展历程,并对钢筋混凝土框架结构抗震加固方法进行了概括总结,分析了每种加固方法的优劣以及其实际工程的应用。最后,总结了抗震加固方法中的节点区加固、局部加固及造价等问题,并对未来抗震加固方法进行了展望,可为工程技术人员在对钢筋混凝土框架结构进行抗震加固时提供参考。

An earthquake is a sudden common and devastating natural disasters. Since the earthquake threat to national property and human life is gTowing, thus building seismic strengthening work is becoming increasingly important. This paper mainly describes the need for seismic reinforcement work, reviews the development process of seismic reinforcement work, and reinforced concrete frame structure seismic retrofit methods were summarized, analysis of the pros and cons of each reinforcing the application of the method and its practical engineering. ,Finally, summarize the seismic reinforcement method node area reinforce- ment, partial reinforcement and cost issues, and seismic strengthening methods are the future, can provide references for engineering and technical personnel in the reinforced concrete frame structure seismic reinforcement.
