在过去和最近发生了大量的事故与可拆卸的看台。这种结构的性能是本文的主题。首先，介绍和讨论了实际看台的结构细节和一些结构体系。接下来，详细介绍了设计、安装和检查过程的细节。最后，可拆卸看台倒塌的情况进行了调查和讨论。在1889年至2008年期间，共发生了93起坍塌事故，造成85人死亡，6,350人受伤。从中选出了35个有倒塌原因信息的案例。对原因的分析表明，意外或过大的载荷是主要的原因，其次是支撑、连接和支撑的问题。可能采取的措施，旨在尽量减少这些结构的事故风险进行了讨论。
A significant number of accidents has occurred with demountable grandstands in the past as well as recently. The performance of such structures is the subject of this paper. First, structural details and some structural systems of actual grandstands are presented and discussed. Next, specifics of the design, erection, and inspection process are detailed. Finally, a survey of cases of collapse of demountable grandstands is presented and discussed. Ninety three cases of collapse were found between the years 1889 and 2008, in which more than 85 people died and 6,350 were injured. From these, 35 cases in which information about the causes of collapse were available were selected. An analysis of the causes showed that unexpected or excessive loads were the major contributing cause, followed by problems with the supports, connections, and bracing. Possible measures that could be adopted aimed at minimizing the risk of accidents with these structures are discussed.
