既有建筑结构加固改造与性能提升现状与发展

Current Situation and Development of Retrofitting and Performance Improvement for Existing Building Structures

我国城市发展已经从增量规划转向存量规划,以高质量发展为目标的既有建筑结构加固改造与性能提升将成为当前甚至相当长时期内建筑领域的主要工作。文章介绍了既有建筑结构从加固改造到性能提升的发展历程,从安全性和抗震性能鉴定、加固改造与性能提升技术、韧性评价三个方面系统阐述了国内外关于既有建筑结构改造的最新研究成果,并指出了既有建筑结构安全性和抗震性能鉴定中存在的技术问题。最后,对未来既有建筑结构加固改造与性能提升未来发展方向做出了展望。

China's urban development has shifted from incremental planning to inventory planning.With the goal of high quality development,retrofitting and performance improvement for existing building structures have become the main task of building sector at present or even for a quite long time.The paper introduced the developmet process from retrofitting to performance improvement of existing building structures,systematically expounded the latest research results of existing building structure reconstruction at home and abroad from three aspects:safety and seismic performance appraisal,retrofitting and performance improvement technology,and resilience evaluation.Moreover,the technical problems existing in the safety and seismic performance evaluation of existing building structures were pointed out.Finally,the future development of retrofitting and performance improvement for existing building structures was prospected.
