This study introduces the Differential Transform Method (DTM) in the analysis of the free vibration response of a rotating closed section composite, Timoshenko beam, which features material coupling between flapwise bending and torsional vibrations due to ply orientation. The governing differential equations of motion are derived using Hamilton’s principle and solved by applying DTM. The natura...

deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. the governing differential equations and c...

Tubed-reinforced-concrete (TRC) columns are gaining increasing popularity in engineering constructions, however, research on their fire performance is still limited and mainly focused concentrically-loaded columns. In this study, extensive numerical analysis was carried out to investigate the of square rectangular TRC under eccentric loading exposed ISO 834 standard fire. A sequentially-coupled...

This paper conducts an investigation towards main aircraft cabin parameters. The aim is two-fold: First, a handbook method is used to preliminary design the aircraft cabin. Second, an objective function representing the “drag in the responsibility of the cabin” is created and optimized using both an analytical approach and a stochastic approach. Several methods for estimating wetted area and ma...

This paper details tests on steel-wood-steel connections with thin dowels carried out at the University of British Columbia in Vancouver, Canada. Connections configurations were selected in such a way that the influence of the main parameters such as dowel slenderness ratio, dowel strength, fastener spacing and end distance and the number of dowels could be studied. An important issue of the pa...

Background: In this paper, the influence of Ramberg-Osgood exponent on ultimate behaviour H-shaped (or I-shaped) aluminium beams subjected to non-uniform bending moment is investigated. Methods: particular, results a wide parametric analysis recently carried out by authors are herein exploited point material properties. The flange slenderness, flange-to-web slenderness ratio, and non-dimensiona...

Abstract In this paper, for steel pipe members with a slenderness ratio of 120, spoilers different numbers and spacings are arranged to test the vibration reduction effect. Wind tunnel results show that 7 sets size 1D×0.5D can basically suppress member. When spoiler spacing is 1D~4D, maximum amplitude more than 90%.
