Structural design of a prefabricated shock absorption residential building in Shanghai
A prefabricated shock absorption residential project is located in the central urban area of Shanghai,the project mainly adopted rigid composite pile to solve the special requirements of the engineering on construction environment,period and cost etc.In view of the adverse effects of the out-of-code project,the shock absorption technology was applied in the prefabricated integral shear wall high-rise residential building,which reduces the seismic action,improves the seismic performance,saves materials and accelerates progress of the construction.In the prefabricated shear wall concealed column connected with the metal coupling beam damper,the longitudinal steel bar was quickly connected by a new adjustable mechanical connection sleeve to ensure the safety and reliability.In the design of prefabricated composite beams,a new type of dry connection node was used to effectively improve the construction progress.The application of key technologies such as rigid composite pile,shock absorption design and new connection were mainly discussed and analyzed.The project is a beneficial attempt to use green and low-carbon technology for structural design,which can provide references for similar projects.
