上海崇明体育训练基地7#篮球馆为篮球运动员进行训练及比赛的场所,楼盖采用钢桁架及组合楼板体系,最大跨度达37m,由于其上进行有节奏运动,容易诱发楼盖体系的竖向振动,造成人员不适。分别采用规范中的简化计算方法及详细的有限元分析计算结构的加速度响应,考虑了运动员跑动及跳跃等多种工况,并以0.5m·s-2为竖向加速度限值,给出了3种楼盖体系方案的舒适度评价。结果表明,可通过适当加大次梁截面及楼板厚度等措施来控制楼盖的舒适度,该工程楼盖体系具有适宜的刚度和舒适度。
Shanghai Chongming Sports Training Center # 7 basketball court is a place for training and competition for basketball players. The building is made of steel truss and composite floor system with a maximum span of 37m. Due to the rhythmic movement on it, the vertical orientation of the floor system is easily induced Vibration, causing discomfort. The acceleration response of the structure is calculated by the simplified calculation method in the standard and the detailed finite element analysis respectively. Considering the running and jumping conditions of the athletes, the vertical acceleration limit of 0.5m · s-2 is given 3 kinds of floor system comfort program evaluation. The results show that the comfort of the floor can be controlled by appropriately increasing the section of the secondary beam and the thickness of the slab. The floor system of the project has suitable rigidity and comfort.
