某体育运动学校的篮球训练馆为大跨度楼盖,在人的正常使用过程中的跑动、跳跃等活动会对楼盖产生特殊的激励,因此有必要分析楼盖的舒适度。采用MIDAS Gen有限元软件建模,对简化后的单层楼盖进行特征值模拟,然后对多人连续行走、多人跑动、多人跳跃三种人行激励下的楼板峰值加速度进行时程分析。 The basketball training hall of a sports school is a large-span floor. The movements, jumps, and other activities that occur during the normal use of people will generate special incentives for the floor. Therefore, it is necessary to analyze the comfort of the floor. Using MIDAS Gen FEM software modeling, simulating the eigenvalues ​​of the simplified single-story floor, and then carrying out time-history analysis of the floor acceleration caused by three kinds of pedestrian-driven continuous walking, multi-person running, and multi-person jumping. .
