The Technique of Seismic Isolation in Story-Adding Buildings Using Light-Weight Steel Structure and its Application

Abstract

Light-weight steel structure story-adding is a widely used technology in house reconstruction. In this paper, it introduces an technique that using seismic isolation theory in story-adding buildings using light-weight steel structure. On the basis of mechanism analysis, a number of lead rubber bearings（LRB）are set between the top storey of existing building and the newly light steel structure, and the upgraded building is developed as a TMD shock absorber system. Combined a project instance, the relevant technical measures and detail constitutions are given. It should be reference to storey-adding engineering designs.
