The effect of perforations on the deformability of welded beam with corrugated webs

open access: yesИнженерно-строительный журнал, 2019
Perforating steel beams is inevitable in some cases such as setting the technical equipment, though it decreases the carrying capacity of the element. The lack of information about the nature of the work, the values of critical stresses, the stability of

OPTIMAL HEIGHT OF STEEL PLATE GIRDERS WITH CORRUGATED WEBS

open access: yesBulletin of Odessa State Academy of Civil Engineering and Architecture, 2020
Abstract. This work is carried out in order to study the classical problem of determining the optimal height of a plate girder with given moment of resistance in relation to the features of the real operation of a beam with a corrugated web. A bi-symmetric plate girder with a wavy web is considered.

Oriented Corrugated Web Steel Beams

open access: yesIOP Conference Series: Earth and Environmental Science
Abstract I-section steel beams are highly used in steel structures, and the point of corrugated beams was had become known recently. In this research, various orientation assemblies of corrugated web steel beams were investigated to study the effect of web corrugation on flexure and shear behaviour.
