Abstract:
The present group of inventions pertains to building and mechanical engineering and can be implemented in load-carrying components of structures. Thin-webbed profile member is intended for reacting primarily compressive load and is embodied with shape and cross-section dimensions constant along its length. Three variants of thin-webbed profile members are proposed. The novelty is embodiment of the shapes with optimum relations of cross-section dimensions corresponding to minimum mass. Two variants of panel are based on all three variants of thin-webbed profile members installed in longitudinal or in longitudinal and transversal directions. Thin-webbed profile members installed longitudinally form with the sheet the open or closed cross-section configuration. The novelty is embodiment of the panels with optimum relations of cross-section dimensions of thin-webbed profile members, thickness of the sheet, pitch of longitudinal and transversal installation corresponding to minimum mass of the panel.
