SAFETY ASSESSMENT AND REINFORCEMENT SUGGESTIONS FOR A CERTAIN FRAME SHEAR WALL STRUCTURE
Due to usage requirements,a certain central building is a frame shear wall structure has been increased from ten floors to fourteen floors.The safety of the building is evaluated through visual inspection,concrete strength testing,dynamic performance testing,as well as structural bearing capacity calculation and seismic analysis.The re-sults show that the concrete strength grade of its main components meets the design requirements,and the overall load-bearing structure has no major problems.Nevertheless,the structures are subject to safety hazards by adding layers and exposing steel bars,which no longer meet the requirements of the specifications.The conclusions of the paper may provide the reference for the later reinforcement and repair treatment.
