The Bottom-Up Underpinning Construction Technology for Base Isolation Reinforcement of the Existing Masonry Structure

Abstract:

Base isolation technology is a new effective way in strengthening and reconstruction projects for the existing buildings. Underpinning technology is to shift the base force from upper structure to isolation layer bearings in strengthening process. How to implement the underpinning technology is the key of base isolation reinforcement for masonry structure. A bottom-up underpinning construction technology and construction procedure for base isolation strengthen design is put forward in this paper. Based on the study of a primary school masonry building, the isolation reinforcement design by using bottom-up underpinning technology is introduced, afterwards, structure dynamic response is performed by dynamic time history analysis with the finite element analysis software Etabs. The result shows the advantages of this new technology compared with conventional reinforcement method for similar works reference.
