6.2.2.2既有工程结构减隔震加固技术与装置我国大部分城市位于抗震设防中、高烈度区，工程结构抗震加固改造是城市更新的重要组成部分，也是确保既有工程结构抗震性能、民众人身与财产安全的重要措施。由于历史遗留问题、结构老化、规范更新、区域抗震设防等级提升、工程结构使用功能变化等多重因素，大量既有工程结构函须进行抗震加固。但传统加固方法通常通过直接提升构件承载力来提升结构的抗震性能，存在加固成本高、施工周期长、影响居民正常生活等系列难题。随着我国韧性城乡战略的推进，消能减隔震技术（安装阻尼器、隔震装置等）可显著提高结构抗震性能，相较于传统加固技术，展现出显著的优势。 1）高性能加固工程材料：包括高强、高延性、自修复等新型高性能工程材料的制备、设计、施工及维护技术。 2）新型耗能减隔震装备：包括高阻尼、大变形、自复位、自适应、高耐久性等高性能新型耗能减隔震装备的制造、设计、施工和运维技术。 3）结构韧性整体提升技术：传统工程结构通常采用抗震结构体系，在加固改造过程中，通过增加减隔震装置或改造工程结构的防震机制，将原有抗震结构改造升级为减隔震结构体系，可有效降低地震时的地震效应或提升结构的防震性能，包括工程结构的减隔震加固设计、改造与运维技术。 4）高效低干预加固修复技术：通过预制化及模块化设计、施工等技术，可大幅提升既有工程结构加固的效率，大幅压缩施工周期，降低对周边工程设施和居民正常生活的影响，同时也可降低整体加固项目的碳排放，实现既有工程结构加固的低干预、高效施工与绿色化。 “既有工程结构减隔震加固技术与装置”工程开发前沿的核心专利有 241件，平均被引数为专利占比达94.19%，是该工程开发前沿的重点研究国家之一，平均被引数为3.71。
