平面超长混凝土结构温度收缩作用分析
emperature and Shrinkage Stress Analysis on Over-long Concrete Structure
工程建设中，很多平面超长结构为满足建筑的功能需要，不能按照规范设置伸缩缝，此时，结构将会在温度及收缩效应作用下，产生较大的温度收缩裂缝，从而影响结构使用及耐久性。该研究从解决不设缝对结构的影响出发，根据温度收缩应力理论，从一个结构工程师的角度，建立了工程应用中温度收缩作用分析方法；并结合广州的一个工程案例的气温统计资料及施工与使用阶段温度收缩工况，运用ETABS结构分析软件，就温度收缩作用对超长结构的影响进行了分析计算，并在分析结果的基础上，确定了具有针对性的工程裂缝控制措施。
Recently, a lot of over-long concrete structure can not be designed with movement joints in accordance with the structure specifications for the functionality of the building. By the influence of temperature and shrinkage, the structure will have some cracks, thus will affect the use and durability of the building. This paper settled the analysis method of temperature and shrinkage stress in the view of a structural engineer and analyzed an over-long concrete structure in Guangzhou with the software of ETABS. Based on the analytical results, this paper proposed control measures to deal with temperature crack.
