| 摘要: |
| 人行等荷载作用引起的振动舒适度是悬挑结构正常使用极限状态设计的重要内容, 悬挑结构在荷载作用下有可能产生较大的动力响应,可能会引起人体的不舒适感. 以某大学综合楼伸缩缝两侧悬挑梁板在荷载作用下会产生明显的竖向位移为例,对其进行了外观尺寸检查、静载和动载试验,测出了它的自振频率和位移幅值,并进行了相应的舒适度评价,为房屋悬挑结构振动舒适性评估提供了试验依据. |

| Abstract: |
| The vibration comfort caused by human action is an important part of the cantilever structure 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,the appearance size, static load and dynamic load test were carried out, and the natural frequency and displacement amplitude were measured,and the comfort degree was evaluated.It provides the experimental basis for the vibration comfort evaluation of the housing suspension. |
| Key words: the cantilever structure comfort evaluate natural frequency of vibration |
