Xinjiang Construction News: On May 12, the special day of national disaster prevention and mitigation, the installation procedure of the building friction pendulum isolation bearing of the office building construction project of the Xinjiang Institute of Seismic Reduction and Isolation Technology officially started, and the positioning, leveling and fixation of the embedded plate under the bearing were completed, laying a solid foundation for the next step of the overall bearing installation and the completion of the isolation building.

This is the first engineering example of practical application of building friction pendulum isolation bearing products in China after the official implementation of the national standard Building Friction Pendulum Isolation Bearing. The Xinjiang Institute of Seismic Reduction and Isolation Technology specially selected this anniversary for construction, which has special commemorative significance.

In order to help Xinjiang build into an "advanced province of earthquake resistance and disaster prevention", the Xinjiang Institute of Seismic Mitigation and Isolation Technology played a leading role in the demonstration of earthquake resistance and disaster prevention when relocating new sites and starting the construction of new office buildings and other series of projects, and specially cooperated with Hengxiang Science and Technology Co., Ltd., a leading enterprise in engineering facilities and equipment in China, to participate in the research, development, design and manufacture of friction pendulum isolation bearings, The six storey steel concrete frame structure office building is built into a "seismic isolation building".

Xinjiang is an earthquake prone area. In recent years, the Xinjiang Uygur Autonomous Region has actively promoted earthquake mitigation and isolation technology. The Department of Housing and Urban Rural Development of the Autonomous Region and the Urumqi Municipal Bureau of Housing and Urban Rural Development have successively issued important documents such as the Notice on Strengthening the Quality and Safety Management of the Application of Seismic Reduction and Isolation Technology in Urumqi Construction Projects (UJF ([2015] No. 128), and the Notice on Accelerating the Application of Seismic Reduction and Isolation Technology in the Autonomous Region (2018-05-08), Actively and effectively promote the seismic mitigation and isolation technology, and the promotion and application of seismic mitigation and isolation technology has taken the lead in the country.

In 2019, the national standard GB/T37358-2019 - Building Friction Pendulum Isolation Bearings was released, which clarified that isolation technology is one of the effective ways to reduce earthquake disasters from the national level.

The anti-seismic structure is to resist the anti-seismic force through the building itself, such as adopting the integral frame structure; The isolation structure improves the seismic resistance by using damping products, such as base isolation bearing and buckling restraint support. The purpose of both is to provide the anti-seismic capacity of buildings, but now there are more and more high-rise and super high-rise buildings. The anti-seismic structure of buildings can no longer meet its own anti-seismic requirements. Only by adding additional damping products can the overall seismic requirements of the structure be met. Hengxiang Technology Co., Ltd., an enterprise implementing the National Torch Plan, is an enterprise specializing in the research, development, design and production of building damping products. The damping products we have now include buckling restrained brace, viscous damper, metal damper, viscous damper, friction damper, multiple types of isolation bearings, etc.

Xinjiang Institute of Seismic Reduction and Isolation Engineering Technology (Co., Ltd.) is a scientific research institution integrating research and test development of seismic reduction and isolation engineering technology, inspection and detection services of seismic reduction and isolation products, and traceability platform of seismic reduction and isolation products. It relies on science and technology, strengthens basic research, and achieves the goal of earthquake prevention and disaster reduction with scientific and technological progress. They give full play to their technical advantages in earthquake prevention and disaster reduction, seek diversified development in the research and experimental development of earthquake prevention and disaster reduction technology, help Xinjiang become a leading province in the research of earthquake prevention and disaster reduction technology in China, meet the market demand of Xinjiang, and fill the gap in Xinjiang.
