寒冷地区室内外温差对结构造成的危害与防治
Damage due to difference between indoor and outdoor temperatures in cold areas and its prevention
【摘要】 寒冷地区的一些建筑物,因设计人员只重视荷载直接作用而忽略了室内外温差对结构的间接作用影响,导致了结构构件过大的裂缝而危及正常使用。本文简要介绍了温度间接作用的理论分析方法,通过对某大厦旋转餐厅与某市政府带外装饰柱框架结构的温度作用定量分析,说明了它对结构的危害性。最后归纳了防治这种危害的主要措施,以供参考。
【Abstract】 Presents the theoretical analysis of the indirect effect of temperature difference the quantative analysis of two frame structures: (a rotational restaurant, and a municipal administration building with exterior decoration columns) to show the effect of temperature difference and suggests measures to prevent such a damage.
