Abstract

Temperature stress is one of the key problems needed to be solved in concrete frame structures with large longitudinal length.In this paper,the temperature stress in the slab of the frame is divided into two parts.One is averagely distributed,which is caused by the axial forces,while the other is located in a limited region,which is caused by the bending of the columns and the beams. Simplified calculation equations are also provided,and the distribution characters of these two types are analyzed and compared.Numerical example shows the promoted equations are easy to use and have fairly good accuracy.
