Buckling design of confined steel cylinders under external pressure
(2010)Thin-walled steel cylinders surrounded by an elastic medium, when subjected to uniform external pressure may buckle. In the present paper, using a two dimensional model with nonlinear finite elements, which accounts for ... -
Concise and accurate solutions to half-space binary-gas flow problems defined by the McCormack model and specular-diffuse wall conditions
(2004)An analytical version of the discrete-ordinates method (the ADO method) is used to establish concise and particularly accurate solutions to the viscous-slip and the half-space thermal-creep problems for a binary gas mixture. ... -
Contribution to the design methodologies of piled raft foundations under combined loadings
(2016)Although simplified design methods for piled raft foundations have been proposed to allow for the group effect and soil-pile-raft interaction, most of them are concentrated on one type of loading, rendering the applicability ... -
Design of reinforced embankments: Limit equilibrium and numerical methods
(2010)The aim of this paper is a comparative study of a reinforced embankment using two different design approaches. The first methodology is based on the limit equilibrium approach and the fundamental aspect of achieving ... -
Direct numerical simulation of dynamo transition for nonhelical MHD
(2010)Pseudospectral Direct Numerical Simulation (DNS) has been performed to simulate dynamo transition for nonhelical magnetohydrodynamics turbulence. The numerical results are compared with a recent low-dimensional model [Verma ... -
Explicit extension of the p-y method to pile groups in sandy soils
(2014)The method of "p-y" curves has been extensively used, in conjunction with simplified numerical methods, for the design and response evaluation of single piles. However, a straightforward application of the method to assess ... -
Finite element analysis of sloshing in horizontal-cylindrical industrial vessels under earthquake loading
(2005)The present paper presents a finite-element formulation for earthquake-induced sloshing in horizontal-cylindrical industrial vessels. Assuming small-amplitude free-surface elevation, a linearized sloshing problem is obtained, ... -
Interaction of retaining structure with adjacent building: Multi-stage numerical analysis
(2012)Large settlements induced to a multi-store building at the initiation of the construction of a diaphragm wall led to a demand of re-dimensioning the initial retaining measures. To achieve this target a multi-stage numerical ... -
Introducing a new hall effect sensor - Novel dynamic offset reduction method
(2011)Silicon Hall plates show an offset of a few millitesla. A large portion of this offset is caused by mechanical stress in the device. The offset can be reduced when the spinning-current principle is applied. In this paper ... -
Lateral loading of internally pressurized steel pipes
(2005)The paper examines the denting response of tubular members and pipes subjected to lateral (transverse) quasi-static loading, in the presence of internal pressure. Tubes are modeled with nonlinear shell finite elements, and ... -
Numerical Evaluation of Pile Response Under Combined Lateral and Axial Loading
(2018)Piled foundations are frequently subjected to simultaneous axial and lateral loadings. However, the interaction effects of the one loading on the other are, in most cases, disregarded for the sake of simplicity. With the ... -
Numerical study on thermal buckling of empty thin-walled steel tanks under multiple pool-fire scenarios
(2018)Fire incidents at fuel storage tank farms are high risk incidents due to the fact that can result in severe socio-economic losses, injuries, deaths and have a serious environmental impact. In the case of a tank fire, there ... -
Parametric investigation of lateral spreading of gently sloping liquefied ground
(2010)This paper investigates the main parameters affecting the anticipated maximum surface displacements due to earthquake-induced lateral spreading of mildly sloping ground. The main tool used for this purpose is a numerical ... -
Response of pile groups in clays under lateral loading based on 3-D numerical experiments
(2010)The response of laterally loaded pile foundations may be significantly important in the design of structures for such loads. Although simplified numerical methods are reliable for evaluating the response of a single pile ... -
Rotational capacity of pre-damaged I-section steel beams at elevated temperatures
(2017)Structures submitted to Fire-After-Earthquake loading situations, are first experiencing inelastic deformations due to the seismic action and are then submitted to the thermal loading. This means that in the case of steel ... -
