设计中庭时所遇到的最大问题是一旦发生火灾,如何保证建筑物中所有人员的安全问题。普通建筑物对防火处理的基本方法是设置防火隔(compartmcntarion);或者发生局部火灾时,设法把火灾限制在那一范围之内。但是中庭建筑,其防火隔断被上下贯通的巨大空间所破坏,因此,如中庭的防火设计不合理时,建筑物中的所有人员都有遭灾的可能性。中庭建筑着火时出现的具体问题有以下见个方面: (1) 火灾规模急剧地无止境扩大;

The biggest problem encountered in the design of the atrium is how to ensure the safety of all personnel in the building in the event of a fire. The basic method for fireproofing of ordinary buildings is to set fireproof compartments; or, in the event of a local fire, try to limit the fire to that range. However, in the atrium building, its fireproof partition is damaged by the huge space that passes up and down. Therefore, if the fireproof design of the atrium is unreasonable, all the people in the building are likely to be affected. The specific problems that arise when the atrium building is on fire include the following aspects: (1) The scale of the fire is rapidly expanding;
