高层工业办公双用厂房振动舒适度研究

High-rise industrial plants can meet the needs not only for industrial production, but also for personnel for office work. In order to study the vibration comfort of this kind of building, taking a high-rise industrial and office dual-purpose factory building under construction as the background, the finite element software was used to establish the overall structure model of the factory building, and the excitation load was applied to a certain floor. The vibration acceleration time-history curves of the excitation floor, the upper and lower floors of the excitation floor were extracted, and the transmission of vibration response was analyzed. In order to ensure the accuracy of the finite element model, the method of combining experimental tests with theoretical calculations was used to excite a certain floor and extract the vibration of the excitation floor. Acceleration time-history data were subjected to frequency spectrum analysis to obtain its vertical first-order natural frequency. The accuracy of the model was verified by comparing test results, theoretical calculation results, and finite element simulation results. According to the finite element simulation results and relevant specifications, it is concluded that the high-rise industrial office building will not resonate under human-induced loads and meets the requirements of vibration comfort. The vibration responses in the building can be transmitted to lower floors where exist attenuation, and the transmission ratio decreases with the decrease of the floor level. The vibration responses in the building can be transmitted to upper floors and the response increases, and the transmission ratio increases with the decrease of the floor level.
