TEMPERATURE EFFECT ANALYSIS OF SMALL HOLLOW CONCRETE BLOCK BUILDING

摘要：

In this paper, the temperature load in Qinhuangdao city was calculated according to its weather temperatures. Numerical simulation of the one-dimensional steady-state temperature field for small hollow concrete block wall was completed using finite element method, and the temperature field distribution in the wall was obtained . The temperature stress of single-chip wall was analyzed using the method of heat-structure coupling field. Furthermore, the influence factors on temperature stress were considered, which were space of extension gap, change of temperature difference, roof insulating layer and core column or construction column on both sides of structural opening. Finally, some effective measures for controlling temperature cracks were summarized.
