Abstract

shell spread widely, especially in public places and halls. In this research, we will study hemispherical domes made of reinforced concrete, which have a hinged support at the ends under the influence of buckling, in order to find out the relationship of the radius to thickness ratio to the buckling coefficient, which serves as a safety factor against buckling, as well as The radius-to-thickness ratio is related to the shape of the resulting buckling and the type of load applied. The study concluded that the dominant buckling shape is not related to the ratio of the shell’s radius to its thickness. This shape varies depending on the type of load overlay used, and the value of the buckling factor decreases with the increase in the ratio of the shell’s radius to its thickness. For the same thickness, the effective rate of implementation was determined to be between  and that in order to increase the cross section, the value of the buckling factor decreases.
