The effects of temperature difference of roof layer on structure of reinforced concrete works

Abstract

Temperature is one of the special loads acting on the building structure. Under the influence of changes in environmental temperature, reinforced concrete material might experience elasticity; and when this elasticity is limited it can cause dangerous stress to the building structures. This paper investigates the impact of temperature on the basic structural members (i.e. floor, beam, column, …) of reinforced concrete building structure. The temperature load effect mentioned in this paper is the temperature difference between two opposite faces of the roof deck structure occurring when the above surface generates high temperature whereas the other surface maintains a lower temperature.
