Analysis on Mechanical Characteristics of Important Components in Overlong Frame Structure under Overall Cooling Temperature

Abstract:

In this paper, the overlong frame structure established by software ETABS was analyzed to find out its mechanical characteristics under the working condition of overall cooling temperature. The columns at the ends of the bottom storey, the beams and slabs in the middle of the first floor were the important components affected by temperature action. Various column cross-section sizes and forms as well as the storey heights to the reaction of the important components were analyzed through a series of finite element models. The key to reduce the temperature effects on overlong frame structure was reasonable design of frame columns at the end of the bottom storey, which are the smaller the cross-section stiffness, and the higher the bottom storey, the smaller the internal forces caused by overall cooling temperature in structural components. Some detailing structural measures were put forward to decrease the negative temperature effects.
