A dome subjected to compression forces: A comparison study between the mathematical model, the catenary rotation surface and the paraboloid López Camino, Rafael Center of gravity Singular minimal surface Singular minimal surfaces are models in architecture of domes where compression forces are the only ones acting on the dome. This paper investigates if catenary rotation surfaces and paraboloids are good candidates to substitute the singular minimal surfaces as designs for the construction of domes. Assuming that these surfaces have the same surface area and the same boundary curve, a numerical comparison of the heights of their centers of gravity and the curvatures is presented. This method is performed with Mathematica together with an analysis based on the slope linear regression line. The numerical results demonstrate that the centers of gravity of the two candidates are considerably close to that of the mathematical model. It is also proved that the paraboloids adjust better than catenary rotation surfaces. 2022-06-28T07:16:52Z 2022-06-28T07:16:52Z 2022-08 info:eu-repo/semantics/article López, R.
