Comfort Analysis of the Local Multi-story Long Cantilever Structure of YOFC Industrial Building
Five volumes of YOFC industrial building are connected by atrium,the plan and facade of which are complex with many irregularities such as large overhangs,large spans and large openings.To solve comfort issues of local multi-story long cantilever structure under pedestrian load,SAP2000 software was used to build finite element model and analyze the vibration response under dynamic load.For the multi-story cantilevered structure,the analysis considered interaction between floors obtained the vibration peak acceleration of the cantilevered floor effectively.And the accuracy of the most unfavorable pedestrian frequency was verified by the response spectrum.At the same time,the vibration reduction design was processed against the most unfavorable case and the vibration response of the floor was greatly reduced by setting the tuned mass damper(TMD)with specific parameters.
