Ltd.10.26689/erd.v8i2.14179ArticleAnalysis of Seismic Performance of Masonry Structures Strengthened by External Steel Frame and Isolation Combinationhttps://artdesignp.com/journal/erd/8/2/10.26689/erd.v8i2.14179LiuJiaqi,ZhangBinyi,CaoBingbing2026822026-03-11The combined strengthening technology of external steel frame and isolation is conducive to improving the seismic performance of masonry structures. Their combination enhances structural integrity and bearing capacity through the external steel frame, while giving full play to the role of the isolation layer to weaken seismic energy, forming a collaborative working mechanism. Analysis shows that this combined scheme helps improve the dynamic characteristics of the structure and controls the damage of the main structure within a reasonable range by reducing responses. This study focuses on explaining the working mechanism and effectiveness of this strengthening method, aiming to provide useful references for seismic retrofitting of buildings.
