摘　　要：游乐项目越来越多地被引入到室内,相关游艺设备也被直接搁置在楼板上。对于放在室内楼板上的复杂游艺设备,由于放置的基础条件发生了改变,对结构主体构件设计带来了一系列问题与挑战,如移动荷载的输入和等效、动荷载对结构构件的影响等。在结构设计中,对于此类问题,相关规范并没有给出直接的设计方法。通过对几种典型的游乐设备搁置在楼板上的情况进行分析,结果表明:复杂的节点荷载可以等效成均布荷载,而等效荷载的大小取决于梁系的布置方式;对于放置一些特殊设备的楼板,除静载分析外,还应进行相应构件的疲劳分析。More and more amusement projects are being introduced indoors,and related amusement equipment is directly placed on the floor slab.For the complex amusement equipment placed on indoor floors,due to the change in the base conditions of placement,a series of problems and challenges have been brought to the design of the main structural members,such as the input and equivalence of moving loads,and the impact of dynamic loads on structural members,ect.In the structural design,the relaevant specifications do not provide a direct design for such problems.By analyzing,several typical amusement equipments placed on the floor,the results show that:complex node loads can be equivalent to uniform ones,and the magnitude of the equivalent loads depends on the arrangement of beam system;For beams and slabs with special equipments,in addition to static load analysis,fatigue analysis of the corresponding members should be carried out.
