Refined design models for investigating the stability of the support contour membrane roof on the square and elliptical plans
Abstract: The article deals with the problematic issues of investigating the stability of the reference circuit, which are regarded as common to membrane roofs on rectangular and elliptical plans and are a necessary step in the development of design solutions. Methodical approach for assessing the possibility of loss of stability of the support contour membrane roof has been developed. Criteria for deformation of objects-analogues have been determined, the numerical simulation of the buckling centrally and eccentrically compressed bars, as well as circular and elliptical rings, has been considered for specific example. Values of the calculated stresses for specific embodiments of the membrane roofs have been analyzed. The resulting solutions can specify and estimate the values of the critical force for the elements of the support contour membrane roofs on rectangular and elliptical plans.
Keywords: membrane roofs, compressed-bent support contour, loss of stability, deformation criteria, objects-analogues.
