某体育中心大跨度楼板振动舒适度分析

Vibration Comfort Analysis on Large-scale Floor about a Sports Center

某体育中心采用框架剪力墙结构,其四层楼板为压型钢板-混凝土组合形式,最大跨度达39米.在人行或有节奏的运动荷载作用下,大跨度楼板容易出现舒适度问题.本文通过SAP2000建立楼板的局部模型,采用加速度作为评价指标,对楼板在人行或有节奏的运动荷载作用下的舒适度问题进行分析.

A sports center adopts frame shear wall structure ;its fourth floor with the form of suppres-sion of steel-concrete composite,and the maximum span of the floor is 39 meters.Under pedestrian or rhythmic motion load,the large span floor cause comfort level problems easily.To solve these problems, we analyze the comfort level under the loads of pedestrian or rhythmic movement through setting the local model with the acceleration as evaluation index by SAP 2000.
