Early Highway Construction Cost Estimation: Selection of Key Cost Drivers
(MDPI, 2023)
Cost estimates in the early stages of project development are essential for making the right deci-sions, but they are a huge challenge and risk for owners and potential contractors due to limited information about the ...
Parametric Study of Additional Temperature Stresses in Continuously Welded Rails on Steel Truss Railway Bridges
(MDPI (Basel, Switzerland), 2023)
Additional temperature stresses in continuously welded rails (CWRs) are caused by track/bridge interaction (TBI) due to thermal actions. Exceeding permissible stresses in CWRs on the bridge can lead to track buckling or ...
Control theory-based data assimilation for open channel hydraulic models: tuning PID controllers using multi-objective optimization
(IWA Publishing, 2022)
Reliable water resources management requires decision support tools to successfully forecast hydraulic data (stage and flow hydrographs). Even though data-driven methods are nowadays trendy to apply, they still fail to ...
Bed-mounted Electro Magnetic meters: Assessment of the (Missing) Technical Parameters
(Elsevier, 2019)
Flow measurements in Urban Drainage Systems (UDS) are essential for pollution control and system management. Since the accuracy of, today the most popular, Acoustic Doppler Velocimeters is impeded by several factors, this ...
Structural Behaviour of Axially Loaded Concrete-Filled Steel Tube Columns during the Top-Down Construction Method
(Applied Sciences, 2022)
The paper discusses the structural behaviour of concrete-filled steel tube columns (CFT)
when applied to the top-down construction method as temporary internal supports for ceilings. Their
ultimate capacity to take into ...
Application of Copper Mining Waste in Radionuclide and Heavy Metal Immobilization
(Wiley-VCH GmbH, Weinheim, 2021)
Copper slag flotation tailings (CSFT), as the end waste from copper mining, are evaluated for radionuclide and heavy metal immobilization. Characterization of CSFT based on grain size and mineral composition, surface ...
Service Life Design of Concrete Structures Made of High-Volume Limestone Powder Concrete—Case of the Carbonation-Induced Corrosion
(MDPI, Basel, Switzerland, 2023)
One of the paths to CO2 emissions reduction in the concrete industry is to use low-clinker cements, providing at the same time the performance of concrete that is adequate for application in concrete structures. This paper ...
Hydrodynamic Loads in a Stilling Basin of a Converging Stepped Spillway: An Experimental Study
(MDPI, 2023)
This paper presents a methodology for estimation of hydrodynamic loads acting on the bottom and at the walls of a stilling basin of a stepped chute with converging walls, based on the pressure measurements at the selected ...
Modeling Indoor Particulate Matter and Small Ion Concentration Relationship-A Comparison of a Balance Equation Approach and Data Driven Approach
(MDPI, 2020)
In this work we explore the relationship between particulate matter (PM) and small ion (SI) concentration in a typical indoor elementary school environment. A range of important air quality parameters (radon, PM, SI, ...
An Adaptive Section Discretization Scheme for the Nonlinear Dynamic Analysis of Steel Frames
(Journal of Structural Engineering, 2023)
The paper presents an adaptive section discretization scheme for the inelastic response analysis of structural members with cross sections that can be decomposed into rectangular and circular subdomains. Each subdomain can ...
