Abstract
Táto práca sa zaoberá návrhom a výpočtom membránovej konštrukcie prístrešku nad zvoleným pôdorysom. Ako najvhodnejší tvar bol vybraný hyperbolický paraboloid. Následne boli vykonané tri rôzne dielčie štúdie. V prvej štúdii bol sledovaný vplyv zmeny hustoty siete konečných prvkov výpočtového modelu. Druhá štúdia sa zaoberala vplyvom zmeny geometrie výpočtového modelu. V tretej štúdii bol sledovaný vplyv dotvarovania materiálu výpočtového modelu na deformácie a napätia membránovej konštrukcie. K statickému riešeniu týchto zvolených variant bol využitý programový systém RFEM s použitím modulu RF-FORM-FINDING. Vo výpočte bolo aplikované geometricky nelineárne riešenie.
This work deals with the design and calculation of membrane structure for shelter placed above selected ground plan. The hyperbolic paraboloid was chosen as most optimal shape. Subsequently, three different sub-studies were conducted. In the first study, influence of mesh density on a finite element calculation model was studied. Second study deal with the effect of the geometry changes of the computational model. In the third study, deformations and tensions of membrane structure in relation to material formation calculation model was studied. For the static solution of those selected variant, structural analysis software RFEM and RF-FORM-FINDING add-on module was used. Geometric nonlinear solution was applied in the calculation.
