SAFETYINSIDE has completed a representative project of seismic isolation, support and reinforcement for highly over limit frame structures
2024-09-23
Recently, the No.1 building project of Yunnan Provincial Transportation Planning and Design Institute in China, which is provided with a complete set of seismic isolation solutions by SAFETYINSIDE, has pioneered the use of seismic isolation technology to reinforce the construction of ultra-high limit frame structures nationwide. It has become a model for strengthening and renovating building structures in high-intensity areas, and has opened up a new technological path for improving urban building safety and urban renewal.
Building 1 of Yunnan Provincial Transportation Planning and Design Institute has 12 floors above ground and 1 floor underground, with a building height of 46.5 meters. Due to its early construction, its seismic resistance has significantly decreased and its internal facilities are outdated. After technical appraisal, it is necessary to carry out seismic reinforcement and fire protection renovation.
This is a building with a frame structure that is extremely high, and its reinforcement needs to solve the problems of high seismic resistance requirements, large single column loads, and high construction accuracy requirements. Therefore, we propose an innovative solution of using seismic isolation and replacement reinforcement technology. The relevant technical personnel introduced that through the application of seismic isolation and reinforcement technology, not only can the seismic force of the structure be reduced by more than 50%, greatly improving the seismic performance of the building, but also about 20% of the reinforcement cost can be reduced, and the overall construction period can be shortened. The clever setting of the isolation layer avoids the need to add a separate isolation layer and reduces the impact on the functional use of the first floor of the building. It truly achieves the integration of structural reinforcement and building function, achieving "no markup for seismic resistance and no impact on renovation".
SAFETYINSIDE fully leverages its technological and experiential advantages in the field of seismic reduction and isolation, drawing on and integrating the professional guidance of multiple experts and scholars. The seismic isolation bearing replacement technology used in the project is completed through fine bearing platform design, temporary support layout, and replacement sequence control. The scientific management of the owner, as well as the meticulous implementation of construction and participating parties, ensure the safe and smooth implementation of the project. After the completion of the entire project, it will significantly improve the seismic resistance of the building, comprehensively enhance its functions, and extend its service life. Its various innovative technologies will provide valuable experience and technical demonstrations for seismic isolation and reinforcement of high-rise buildings.
