Pedestrian loads such as beam slab structure caused by the vibration comfort is an important part of the normal use limit state design. Cantilever structure under loading may produce a larger dynamic response,May cause discomfort of the body. for example, in a university building complex building expansion joints on both sides of the cantilever beam under the action of load will produce obvious vertical displacement,On the exterior dimension check,static load and dynamic load test,measure its natural frequency and displacement amplitude,and the corresponding evaluating.SProvide the experimental basis for the cantilever structure vibration comfort evaluationS.
