Abstract: The structural rehabilitation and the tilting mitigation of a seven-story residential building are presented in this paper. The application of commercial finite element software ABAQUS in the designing of the tilting mitigation program and how ABAQUS software achieved the design optimization of program are also discussed in detail. The reasonable pile space and the optimal length of pile are determined from the numerical analysis. Under the background of the national “two-carbon minimization” strategy, through the optimization design of the structural rehabilitation and building tilting mitigation, the overall carbon emissions are effectively reduced while the purpose of the rehabilitation and the tilting mitigation are achieved. After the project, the tilting value of the existing structure is reduced from the maximum of 125mm to 10 mm, and the final tilting ratio satisfies the requirement of national code. The implementation of this project can provide a valuable project case history and a technical reference for the design and mitigation of similar projects.
