Title of the articleImproving the efficiency of the layout profiled sheeting in the covers of multi-span buildings
Abstract.At present, in construction of buildings of light steel structures corrugated steel decks are widely used as a supporting and protecting element of coating. With realization of the building of profiled steel deck its efficiency is largely determined by the scheme of laying. Developed measures to improve efficiency of the profiled steel sheeting in the coatings of light single-story multi-span buildings. The paper proposes to use console layout, in particular, the dual console layout of flooring, which leads to cost on profiled steel decking up to 33 %. The deck layout for the proposed dual console arrangement raises the questions of disc stiffness deck, which is important in ensuring the spatial rigidity of the frame. To study this question experimental and numerical researches were carried out. It was established experimentally that the console areas and overlap deck existence reduces the disk stiffness and for the practical use the overlap of 1,8-2,3 h is recommended, where h is the height of the corrugation of deck. Based on numerical researches finite-element model on PC «Ansys» was developed with coefficients of friction of 0,03 and 0,01 pliability, which allows to model the stress-strain state and can be used in the real calculations of disk stiffness of deck at his console laying and arbitrary block sizes of cover.
Keywords.Steel deck, flooring optimal dual console layout, experimental, numerical researches of disk stiffness.
