  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Strengthening of Steel Columns under Load: Torsional-Flexural Buckling 

    Vild, Martin; Bajer, Miroslav (Hindawi Publishing Corporation, 2016-11-10)
    The paper presents experimental and numerical research into the strengthening of steel columns under load using welded plates. So far, the experimental research in this field has been limited mostly to flexural buckling ...
  • Strengthening under Load: The Effect of Preload Magnitudes 

    Vild, Martin; Bajer, Miroslav (Elsevier, 2016-10-18)
    Strengthening existing structures under load by welding plates is often conducted but little research into this subject was presented. Some researchers claim that the column strengthened under load has the same ultimate ...
  • Strengthening under Load: Experimental and Numerical Research 

    Vild, Martin; Bajer, Miroslav (IOPSCIENCE, 2015-11-02)
