Free Vibration Analysis of a Thin‐Walled Beam with Shear Sensitive Material
Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 This paper presents a method for a free vibration analysis of a thin‐walled beam of doubly asymmetric cross section filled with shear sensitive material. In the study, first of all, a dynamic transfer matrix method was obtained for planar shear flexure and torsional motion.

Bars under Torsional Loading: A Generalized Beam Theory Approach
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 In this paper both the static and dynamic analyses of the geometrically linear or nonlinear, elastic or elastoplastic nonuniform torsion problems of bars of constant or variable arbitrary cross section are presented together with the corresponding research efforts and the conclusions drawn from examined cases with great practical interest.

[Retracted] A Numerical Model for Torsion Analysis of Composite Ship Hulls
Mathematical Problems in Engineering, Volume 2012, Issue 1, 2012., 2012 A new methodology based on a macroelement model proposed for torsional behaviour of the ship hull made of composite material is proposed in this paper. A computer program has been developed for the elastic analysis of linear torsion. The results are compared with the FEM‐based licensed soft COSMOS/M results and measurements on the scale simplified ...

Effect of Construction Method on Shear Lag in Prestressed Concrete Box Girders
Mathematical Problems in Engineering, Volume 2012, Issue 1, 2012., 2012 Most of the previous researches conducted on shear lag of box girders were only concerned about simple types of structures, such as simply supported and cantilever beams. The structural systems concerned in these previous researches were considered as determined and unchangeable. In this paper, a finite element method considering shear lag and creep of

Dynamic Analysis of Horizontally Curved Thin‐Walled Box‐Girder Bridge due to Moving Vehicle
Shock and Vibration, Volume 14, Issue 3, Page 229-248, 2007., 2007 The impact on curved box‐girder bridges due to vehicle moving across rough bridge deck have been analyzed using bridge‐vehicle coupled dynamics. The bridge deck unevenness has been assumed to be a homogeneous random process in space specified by a PSD function.

Dynamic Stiffness Analysis of Curved Thin‐Walled Beams
Shock and Vibration, Volume 1, Issue 1, Page 77-88, 1993., 1993 The natural vibration problem of curved thin‐walled beams is solved by the dynamic stiffness method. The dynamic stiffness of a curved open thin‐walled beam is given. The computed natural frequencies of the beam are compared with those obtained by a completely analytical method to show the high accuracy of the present method.

Advancements to the equivalent compression flange method
Steel Construction, Volume 17, Issue 4, Page 223-241, November 2024.Abstract The simplified method of the equivalent compression flange represents an illustrative and easy‐to‐use engineering model for lateral torsional buckling. The basic concept of the verification procedure has existed since its introduction in the 1950s.

Statyka Mostu o Przekroju Otwartym w Łuku
Engineering Transactions, 1957 The subject of this paper is the derivation of accurate and approximate equations of structural analysis for an open cross-section bridge (Fig. 1). It is assumed that the total torque is equilibrated by a pair of shearing forces in principal girders. The
