    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 ...
  • 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 ...
  • Test Arrangement of Small-scale Shear Tests of Composite Slabs 

    Holomek, Josef; Bajer, Miroslav; Vild, Martin (Elsevier, 2016-10-19)
    Composite slab consists of the layer of concrete above the trapezoidal sheeting. The sheeting serves as a lost formwork as well as a tension bearing member after the hardening of concrete. The interaction between 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 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 ...
  • Strengthening of Steel Columns under Load: Torsional-Flexural Buckling
