RISUncertainties in Vertical Stress Distribution in Spatially Varying Random Elastic Half-Space
Publisher: ASCE
Abstract: This paper presents a comprehensive study on the effect of spatial variability of the elastic modulus on vertical stress distribution in an elastic half-space due to strip loading. The modulus of elasticity is considered ...
Lateral Response of Hollow Circular Caisson Embedded in Nonlinear Soils
Publisher: ASCE
Abstract: This paper presents the numerical analysis of the lateral response of hollow circular caisson embedded in nonlinear soils. The caisson–soil system is modeled by a three-dimensional nonlinear finite-element method. The ...
Development and Calibration of a Simplified Nonlinear Spring Model for Predicting the Lateral Response of Caisson Foundations Using a Multiobjective Genetic Algorithm
Publisher: American Society of Civil Engineers
Abstract: Abstract This study introduces a simplified one-dimensional nonlinear spring model to predict
the lateral behavior of caisson foundations under combined lateral and moment loading
considering nonlinearities at both the ...
Energy-Economic and Exergy-Environment Performance Evaluation of Compact Heat Exchanger With Turbulator Passive Inserts Using THDNF
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Technology innovation requires advanced heat transporting techniques to fulfill better exergy and economic behavior of compact air heat exchangers (HXs). Three different turbulator inserts, TTIs, PTTIs, and DTTIs (twisted ...
Accounting for Endogeneity in Maintenance Decisions and Overlay Thickness in a Pavement-Roughness Deterioration Model
Publisher: American Society of Civil Engineers
Abstract: Pavement deterioration models are an important part of any pavement management system. Many of these models suffer from endogeneity bias because of the inclusion of independent variables correlated with unobserved factors, ...
Real-Time Crash Risk Reduction on Freeways Using Coordinated and Uncoordinated Ramp Metering Approaches
Publisher: American Society of Civil Engineers
Abstract: This study was conducted to examine the ability of two ramp metering strategies at reducing the real-time crash risk along a typical urban freeway. The strategies were tested using a simulated freeway network of Interstate-4 ...
Impact of Mixed Convective and Radiative Heat Transfer in Spiral-Coiled Tubes
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Spiral-coiled tube heat exchangers (SCTHE) have higher heat transfer as compared to the conventional heat transfer devices and are extensively used to extract heat from exhaust gases in the chemical processing industries ...
