- Abstract:
- In order to study the abnormal vibration cause and reinforcement method of high-rise industrial building, finite element analysis method and field vibration test method were adopted, a three-dimensional finite element model of high-rise industrial building was established. Finite element analysis and field vibration test was carried out before reinforcement. Based on strict comfort level, limited reinforcement space and high lighting requirement of high-rise industrial building, a field reinforcement scheme with short leg shear wall was put forward. Comparison analysis of finite element calculation results and field vibration test results before and after reinforcement were carried out. The results show that the machines and high-rise industrial building resonated after machines are installed at the high level of industrial building, and it is the main reason for the abnormal vibration of high-rise industrial building. Strength and stiffness of reinforced high-rise industrial building are obviously improved, natural frequency of length direction of high-rise industrial building is improved from 2.45 Hz to 5.87 Hz, natural frequency of width direction of high-rise industrial building is improved from 2.94 Hz to 7.83 Hz. Vibration frequency of machines is not in the resonant interval with high-rise industrial building. Vibration characteristics of high-rise industrial building are improved and good reinforcement effects are obtained. Vibration test results and reinforcement methods can provide reference for the design and reinforcement of highrise industrial buildings.
