Novel Empirical Approaches for Predicting the Critical Load of the Dome Structures

Abstract

Due to the properties and ability to cover areas with large spans, the use of the domes has been realized as unique worldwide. With time and technological progress, the engineers have become incumbent to offer precise methods in the least possible time for designing the structures with the highest load-carrying capacity. The parameters used in this study include the height-to-span ratios, diameter, thickness and weight of the structure. Also, two methods have been evaluated for predicting the critical load but spending the shortest possible time. Multiple regression (MR) and step-by-step regression (SR) have been expanded as reliable methods for producing and evaluating the critical load. The data required for the algorithms or training have been acquired from credible databases. The accuracy of the constructed formulas will be confirmed using the proper scales. Then, to investigate the degree of this method’s accuracy, a comparison has been made between the models developed based on the formulas. It is perceivable that despite the trivial difference between the proposed models, the formulas obtained based on (SR) methods provide more accurate results than the ones attained based on (MR) methods. The presented formulas are highly accurate.
