Abstract

Abstract

Due to the change of structural function, one teaching building had to be retrofitted to a large-space office building.The underpinning technology had been adopted to transform this brick-concrete structure to a frame structure.In order to ensure its safety operation, fiber bragg grating technology(FBG) and distributed optical fiber sensor(BOTDA) had been used to monitor structural stress and strain during the whole period of construction.The test results show that the designed underpinning system performances well and can provide sufficient bearing capacity for this new retrofitted structure.
