Numerical study on settlement of piled foundations on homogenous rock
( Taylor and Francis , 2014 , Conference)Settlement behavior of piled foundations on homogenous rock was investigated using an extensive three-dimensional finite element analysis of different piled-foundation models. Effects of pile slenderness ratio, pile spacing, ... -
Settlement of axially loaded piles entirely embedded in rock - analytical and experimental study
( Taylor and Francis , 2012 , Article)Finite element analysis was performed to study the settlement behaviour of axially loaded piles entirely embedded in nonhomogenous rock. The elastic modulus of the rock mass was taken to increase linearly along the pile ... -
Fully softened shear strength for soil slope stability analyses
( American Society of Civil Engineers (ASCE) , 2017 , Article)The fully softened shear strengths of soils, mudstones, and shales of different plasticities and gradations were measured at low (10 and 25 kPa), intermediate (50 and 100 kPa), and high (200, 300, and 400 kPa) effective ... -
Estimating the elastic settlement of piled foundations on rock
( American Society of Civil Engineers (ASCE) , 2015 , Article)This research introduces a simple method for preliminary evaluation of the elastic settlement of piled foundations resting on rock. Despite a significant number of publications in this area, the present effort is distinguished ... -
Bearing Capacity and Settlement of Skirted Shallow Foundations on Sand
( American Society of Civil Engineers (ASCE) , 2013 , Article)The behavior of axially loaded skirted shallow foundations resting on sand was studied using an extensive numerical analysis. Surface, pier, and skirted square foundations resting on sand with different shear strength ... -
A technique for estimating permeability of a randomly fractured rock mass
( Springer Verlag , 2007 , Article)Extensive field and laboratory testing programs were performed to develop a relationship between the permeability of a fractured limestone and the core recovery values. The studied limestone does not encompass any jointing ... -
Factors influencing determination of shale classification indices and their correlation to mechanical properties
( Springer Verlag , 2006 , Article)The influence of sample preparation procedure on the measured classification indices such as clay-size fraction, liquid limit, and plastic limit of shales was investigated. Shale samples covering a wide range of composition ... -
Two- and three-dimensional analyses of translational slides in soils with nonlinear failure envelopes
( Canadian Science Publishing , 2010 , Article)This paper aims to assess the effect of nonlinearity of the soil shear strength envelope on the sliding mass con-figurations and the minimum two- and three-dimensional factors of safety for slopes susceptible to translational ... -
Geotechnical considerations on the design of piled rafts on rock
( Research Publishing Services , 2011 , Conference)This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ... -
Comparative study on the behavior of square foundations resting on confined sand
( Canadian Science Publishing , 2009 , Article)The behavior of shallow foundations resting on laterally and (or) vertically confined sand has been investigated using physical and numerical modeling. The models were designed to simulate the frequently constructed raft ... -
Stability analysis and charts for slopes susceptible to translational failure
( Canadian Science Publishing , 2006 , Article)The aim of this paper is to develop two- and three-dimensional stability charts for slopes susceptible to translational failure. An extensive parametric study was conducted using a slope model that is designed to simulate ... -
MODAL CHARACTERIZATION AND ROAD ROUGHNESS RECONSTRUCTION USING DYNAMIC VEHICLE ACCELERATIONS AND ANNS
( National Technical University of Athens , 2023 , Conference)Road networks are considered huge and critical infrastructures that support the development and growth of societies. These infrastructures deteriorate over time due to regular usage and/or external environmental factors. ... -
Investigating the effect of using softer rail-pads on ground-borne vibration from underground railways
( Taylor and Francis Ltd. , 2023 , Article)In this study, a series of vibration measurements were performed on a section of one of the lines of the Doha Metro to explore the effect of changing rail-pads from conventional higher stiffness under-rail pads to lower ... -
Road Profile Estimation Using Full/Quarter-Car Model with Artificial Neural Networks
( Springer Science and Business Media Deutschland GmbH , 2024 , Conference)The monitoring of road roughness is one of the first and most critical steps in road maintenance. Road networks need constant maintenance to function properly and avoid any hazardous accidents or blockage of the traffic ... -
Publisher Correction: Application of Metastructures for Targeted Low-Frequency Vibration Suppression in Plates
( Springer , 2023 , Article)The publication of this article unfortunately contained a mistake, the Figs. 12b and 14b were missing. Below you can find the complete Figs. 12b and 14b: The original article has been corrected. -
Optimization of Viscoelastic Metamaterials for Vibration Attenuation Properties
( World Scientific , 2020 , Article)Metamaterials (MMs) are composites that are artificially engineered to have unconventional mechanical properties that stem from their microstructural geometry rather than from their chemical composition. Several studies ... -
Reconstruction of Road Defects from Dynamic Vehicle Accelerations by Using the Artificial Neural Networks
( Springer Science and Business Media B.V. , 2023 , Conference)Monitoring of roads is considered the first step in establishing a successful road maintenance program, which includes scheduling adequate maintenance to a certain road section at the right time. Road monitoring assesses ... -
PREDICTING ROAD ROUGHNESS PROFILE USING DYNAMIC VEHICLE ACCELERATIONS AND ARTIFICIAL NEURAL NETWORKS
( Society of Acoustics , 2022 , Conference)Road roughness can cause ride discomfort and contribute to the emission of ground-borne noise and vibration. A robust monitoring regime of road roughness is essential for the efficient maintenance of a country's road ... -
