Strength and stiffness of cold-formed steel portal frame joints using quasi-static finite element analysis

open access: yes, 2017
This paper describes a quasi-static finite element analysis, which uses the explicit integration method, of the apex joint of a cold-formed steel portal frame. Such cold-formed steel joints are semi-rigid as a result of bolt-hole elongation. Furthermore,

Features of application of bimoment theory of V.Z. Vlasov in the calculations of reinforced concrete bar structures

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract In this paper, an adaptation variant of the “deformation model” is proposed for estimating the parameters of the stress-strain state of a reinforced concrete bar element with flexible discrete reinforcement, taking into account the deplanation of concrete and the features of contact interaction between reinforcement and concrete.

Class 4 Sections Computing Section Properties and Stresses Due to the Bimoment

open access: yes
The present paper deals with warping torsion, bending and axial forces. Presenting a method to compute the shear center of the effective section, the warping constant and warping coordinates needed to compute the stresses due to the bimoment. The stresses are compared between stresses in the gross and effective section when a Bimoment only is applied ...

Development and verification of yield surfaces for I-sections

open access: yes, 2009
THESIS 9263In the design of many building structures for ultimate states the use of interaction equations is quite common. Despite this there is still a need for more advanced and flexible equations which consider all forces in space.

Moment determinants as isomonodromic tau functions

open access: yes, 2009
We consider a wide class of determinants whose entries are moments of the so-called semiclassical functionals and we show that they are tau functions for an appropriate isomonodromic family which depends on the parameters of the symbols for the ...

A new 3D-beam finite element including non-uniform torsion with the secondary torsion moment deformation effect [PDF]

open access: yes, 2013
In this paper, a new 3D Timoshenko linear-elastic beam finite element including warping torsion will be presented which is suitable for analysis of spatial structures consisting of constant open and hollow structural section (HSS) beams.
