Go/no-go decision model for owners using exhaustive CHAID and QUEST decision tree algorithms
( MDPI , 2021 , Article)Go/no-go execution decisions are one of the most important strategic decisions for owners during the early stages of construction projects. Restructuring the process of decision-making during these early stages may have ... -
A Comparative Study on the Efficiency of Reliability Methods for the Probabilistic Analysis of Local Scour at a Bridge Pier in Clay-Sand-Mixed Sediments
( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)In this work, the performance of reliability methods for the probabilistic analysis of local scour at a bridge pier is investigated. The reliability of bridge pier scour is one of the important issues for the risk assessment ... -
Modeling of osmotically-driven membrane processes: An overview
( Elsevier , 2023 , Article)In the modern era, mathematical modeling is a promising tool to evaluate the forward osmosis (FO) and pressure retarded osmosis (PRO) systems process feasibility and check the outcome of performance parameters on the overall ... -
Exploring driver behaviors during tailgating situations: a driving simulator study
( Elsevier , 2023 , Conference)The characteristics of drivers vary from one individual to another and one culture to another, leading to distinct driving behaviors exhibited by different drivers. This study aims to explore drivers’ car-following behaviors ... -
Safety assessment of on-road cycling lanes: A comparative study of different layouts using driving simulator
( Elsevier , 2024 , Article)Over the past few decades, a growing attention has been directed toward cycling due to its positive impacts on social, economic, and health aspects. Various countries are adopting and implementing strategies to promote ... -
Identifying the relationship between intention to use flat-rate public transport and trip frequency by a discrete-continuous model
( Springer Nature , 2023 , Article)Public transport fare is a central feature of transit operations and is a key indicator to reflect transport demand. Yet, relatively little is known about how fare influences on ridership dynamics, including for which types ... -
Modeling the Impact of Weather Conditions on Pedestrian Injury Counts Using LASSO-Based Poisson Model
( Springer Science and Business Media Deutschland GmbH , 2021 , Article)Statistical models for measuring the impact of adverse weather conditions on pedestrian injuries are of great importance for enhancing road safety measures. The development of these models in the presence of high collinearity ... -
Simple Procedure for Preliminary Estimation of the Permeability of Randomly Fractured Rock Masses
( American Society of Civil Engineers (ASCE) , 2024 , Article)A data-driven approach is used to show the significant discrepancy between the coefficients of permeability that are estimated through packer field tests and those back-calculated from the actual discharge pumped out of ... -
Undrained interface shear strength of fine-grained soils for near-shore marine pipelines
( ASTM International , 2020 , Article)The peak and residual interface shear strengths for a variety of normally consolidated soils were measured using a torsional ring shear apparatus modified to suit soil and interface testing under the undrained condition, ... -
Estimating the permeability of fractured rock masses for design of construction dewatering systems
( Elsevier , 2023 , Article)A comprehensive data on dewatering and pumping-well systems installed in fractured rock is compiled and analyzed to estimate the permeability of fractured rock masses. The data covers construction activities of different ... -
Comparison of site-specific and empirical correlations for drained residual shear strength
( ICE Publishing , 2020 , Article)The discusser has an interest in the topic of the paper (Hayden et al., 2018) on the ability of empirical correlations to predict the residual friction angle of samples from a specific site. In fact, he provided one of the ... -
Applicability of construction dewatering techniques for randomly-fractured rock
( ICE Publishing , 2024 , Article)Through analyzing a significant number of case histories, ranges of applications of dewatering techniques for randomly-fractured rock are proposed in terms of the rock mass permeability and the required drawdown. The ... -
Macro-scale direct shear test device for assessing soil-solid interface friction under low effective normal stresses
( ASTM International , 2014 , Article)The paper describes a new macro-scale direct shear test device for assessing the largedisplacement soil/solid interface drained shear strength at low effective normal stresses. The testing method arises from a need to ... -
Shear strength of geosynthetic composite systems for design of landfill liner and cover slopes
( Elsevier , 2011 , Article)Torsional ring shear tests were performed on composite specimens that simulate the field alignment of municipal solid waste (MSW) landfill liner and cover system components. Simultaneous shearing was provided to each test ... -
Laboratory testing of full-scale pipes partially embedded in soil to study soil-pipe interaction of offshore seabed oil and gas pipelines - Initial observations
( American Society of Mechanical Engineers (ASME) , 2014 , Conference)The geotechnical aspect of the design of off-shore oil and gas pipelines is a challenge due to inherent uncertainties in predicting soil-pipe interaction behaviour. Physical modeling is often sought after to gain insight ... -
Residual shear strength of fine-grained soils and soil-solid interfaces at low effective normal stresses
( Canadian Science Publishing , 2015 , Article)A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses ([1]3-7 kPa). Soils that cover a wide range of plasticity and ... -
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 ...
