摘要
提出了中庭采用自然排烟所带来的消防问题。采用计算流体力学(CFD)方法对烟气在中庭中的传播进行了模拟分析。通过对模拟结果的分析,提出了有关加强中庭消防安全措施的建议。
Atrium and other large volume space do not have the compartmentation that has been traditionally a major contributor of fire protection. Smoke management systems for large volume spaces is to maintain an enviroment in which the impact of smoke and heat on occupants is not life threatening. This involves keeps the height of the smoke above the highest level of occupancy for a defined period of time, longer than the expected time to evacuate the building.Describes the design approach to gravity smoke venting to achieve fire safety in atrium.
