In this paper the influence of section properties on thin walled beam sections with restrained
torsion is studied by considering the angle of twisting for non-uniform torsion. The study is …

In this paper, the behaviour of thin-walled sections of a bar with restrained torsion is studied.
Neglecting these warping behaviours may generate significant errors, particularly for open …

Various engineering structures include lightweight or thin-walled beam structures that are
used in a complex loading situation which includes restrained torsion of closed or open …

The paper is devoted to the study of constrained torsion in joints of flat thin-walled rod
systems. The goal of the work is to analyze the stress state of finite stiffness joints made of …

A review of modern algorithms and optimization programs is presented, based on which it is
concluded that there is no application software in the field of optimal design of building …

The study object is a three-dimensional triangular prism finite element based on piecewise
constant approximations of stresses. The use of such a finite element makes it possible to …

The aim of the research-to investigate the behavior of thin-walled beam I-section loaded with
bending and torsion using theoretical, numerical, and experimental approaches. In this …

The paper develops the finite element method (FEM) in the form of the force method and in
the mixed form for the calculation of structures. At present, the displacement-based finite …

In a mixed formulation, a four-node finite element was developed, which is a fragment of the
middle surface of the elastic shell. Longitudinal forces and bending moments, as well as …
