Conceptual design and evaluation of the alternative construction of lightweight hall building with polygonal ground plan and canvas roofing

Junga P., Vondráčková T., Mareček J. (2018): Conceptual design and evaluation of the alternative construction of lightweight hall building with polygonal ground plan and canvas roofing. Res. Agr. Eng., 64: 20–25. The paper presents the results of a conceptual study of lightweight wooden construction hall building with polygonal ground plan, suitable for agriculture. It comprises evaluation of chosen technical and functional characteristics and possibilities for animal production. The results of the study confirm advantages (mainly lower material and costs demandingness, environmentally friendliness, light-weight construction, fast assembly operations) and disadvantages (mainly larger range of groundwork, higher demandingness on roof structure, foundation of slab constructions and anchoring of vertical bearing constructions). Values of radial tensile stress at an interval of 9.0 to 21.0 MPa and tangential tensile stress at an interval of 1.4 to 16.0 MPa were calculated on vertical load 100 kN at the top of the construction). The construction makes possible to achieve a span as far as 60 m with effective canvas strain at large radius curvature from 80 m to 100 m.
