Key Reinforcement Technology of the Replacement of High-rise Building Shear Wall Concrete

摘要

A high-rise residential building is the frame-supported shear wall structure. Testing found that concrete strength 6 pieces of shear wall of the tenth floor can not meet the original design requirements of C50 when the nineteenth floor was constructing. A way of replacing concealed column and corner column only by comparison an analysis.The safety of the structure was ensured and good strengthening effect was achieved by reasonable design of temporary support and construction, concrete selection and the whole deformation monitoring.
