超高层建筑烟囱效应问题以及防治措施探讨

Research and prevention measures of stack effect in super high rise building

介绍了高层建筑烟囱效应的形成机理,利用CONTAMW软件,对某建筑进行了冬季工况烟囱效应模拟分析,探讨了烟囱效应热压差系数及通高电梯的压差分布特性,且通过计算分析,提出了烟囱效应的防治措施,保证高层建筑内部电梯正常使用。

The paper introduces the forming mechanism of high-rise building chimney effect,uses CONTAMW software,carries out simulation analysis of chimney effect under winter construction condition,explores heat-pressing difference coefficient of chimney effect and pressing difference distribution property of Tonggao elevator,and finally puts forward effective preventive measures of chimney effect,so as to guarantee normal operation of internal high-rise building elevator.
