The Reliability Of The Identification And Transfer Structure. Qing Xiang Building System Reinforcement Methods Finite Element Simulation Analysis

The original design of structure for Qing Xiang Building is the bottom layer of frame structure and the top five stories are brick structure,but the owner did not construct the building by the original design. The results of the field detection and identified by reliability show that:The project does not meet the reliability requirements of civil construction and was identified as the main structure of the reliability of grade III, there are security risks, needing reinforcement before they can continue to use. Recommend to change structural system.Using finite element software ANSYS10.0 to simulate changing structural system method, which showed that:1, Changing structural system method can change the structure's weak layer position;2, Changing structural system method can solve the problem of asymmetric loads;3, Changing structural system method can effectively reduce the structural layer displacement;4, Reinforce the original structure for the multi-storey masonry structure can only improve seismic performance of reinforcement a little;As seen above, changing structural system was feasible, and then do the structural's optimization design which saved four lateral walls, a vertical wall. Therefore, the optimum design is very necessary for it can save materials and affordable.Using PKPM08 to design reinforcement according to the building's reliability qualification results and above conclusions. Corresponding reinforcement plans. After reinforcement, it was used well, so this method can reference for similar projects.
