Comparison of analytical and numerical methods applied to lateral torsional buckling of beams
Vild, Martin; Piják, Jiří; Barnat, Jan; Bajer, Miroslav; Melcher, Jindřich; Karmazínová, Marcela (Elsevier, 2017-07-21)The paper is focused on the numerical evaluation of transversally loaded beams of one symmetric and four asymmetric cross-section shapes susceptible to lateral torsional buckling. Several analytic methods used for evaluation ... -
Experimental investigation of torsional restraint provided to thin-walled purlins by sandwich panels under uplift load
Balázs, Ivan; Melcher, Jindřich; Belica, Andrej (Elsevier, 2016-10-19)Sandwich panels, usually used as members of wall or roof cladding, can provide lateral and torsional restraint to metal members of the substructure along their spans. They can positively influence the buckling resistance ... -
Experimental Verification of the Buckling Strength of Structural Glass Columns
Pešek, Ondřej; Horáček, Martin; Melcher, Jindřich (Elsevier Ltd., 2016-10-18)This paper deals with experimental research of axially loaded members made of structural (laminated) glass. The purpose of the research is the evaluation of buckling strength and actual behaviour of the columns due to the ... -
Experimental Verification of the Structural Glass Beam-Columns Strength
Pešek, Ondřej; Melcher, Jindřich; Balázs, Ivan (IOP Publishing, 2017-11-04)This paper deals with experimental research of axially and laterally loaded members made of structural (laminated) glass. The purpose of the research is the evaluation of buckling strength and actual behaviour of the ... -
Focusing on Problem of Lateral Torsional Buckling of Beams with Web Holes
Horáček, Martin; Melcher, Jindřich; Pešek, Ondřej; Brodnianský, Ján (Elsevier, 2016-10-19)This paper deals with the problems of analysis and the design of perforated thin-walled steel Sigma beams with respect to lateral torsional buckling (further LTB). The application of Sigma profiles is in the storage systems ... -
Influence of Uplift Load on Torsional Restraint Provided to Steel Thin-Walled Purlins by Sandwich Panels
Balázs, Ivan; Melcher, Jindřich (Elsevier, 2017-06-03)The sandwich panels have been widely used as members of roof and wall cladding. In addition to their primary function, they can provide lateral and torsional restraints to the supporting members and therefore contribute ... -
Lateral-torsional buckling of laminated structural glass beams. Experimental study
Pešek, Ondřej; Melcher, Jindřich (Elsevier, 2017-06-02)This paper deals with experimental research of stability behaviour of laminated structural glass beams. The purpose of the research is the evaluation of lateral-torsional buckling resistance and actual behaviour of the ... -
On the Problem of the Imperfections of the Structural Glass Members Made of Flat Glass
Pešek, Ondřej; Melcher, Jindřich; Horáček, Martin; Balázs, Ivan (IOP Publishing Ltd., 2019-01-20)This paper deals with initial geometrical imperfections of the structural glass members made of flat glass. The design of the load bearing glass structures is relatively common in modern architecture, but there is not an ... -
Stability of Thin-Walled Beams with Lateral Continuous Restraint
Balázs, Ivan; Melcher, Jindřich (Vysoká škola báňská - Technická univerzita Ostrava, 2015-07-03)Metal beams of thin-walled cross-sections have been widely used in building industry as members of load-bearing structures. Their resistance is usually limited by lateral torsional buckling. It can be increased in case a ... -
Study of Behaviour of Beams and Panels Based on Influence of Rigidity
Pešek, Ondřej; Melcher, Jindřich (Elsevier, 2012-09-26)The aim of this paper is the elaboration of a study on the real behaviour of beams and thin panels considering the effect of large deflection. The classic plate theory was developed for panels whose deflections are lower ... -
Torsional Restraint Problem of Steel Cold-Formed Beams Restrained by Planar Members
Balázs, Ivan; Melcher, Jindřich; Pešek, Ondřej (IOP Publishing, 2017-11-04)The effect of continuous or discrete lateral and torsional restraints of metal thin-walled members along their spans can positively influence their buckling resistance and thus contribute to more economical structural ...
