RISEffect of Concrete Strength and Reinforcement on Time-Dependent Deflection of Posttensioned Slabs
Publisher: American Society of Civil Engineers
Abstract: Posttensioning is an effective construction method for structures with large spans, intensive loadings, and cost-efficiency considerations. The investigation developed a comprehensive understanding of how various reinforcement ...
Modulus of Elasticity of Concrete in Design Codes and Empirical Models: Analytical Study
Publisher: American Society of Civil Engineers
Abstract: The modulus of elasticity (MOE) is a key parameter in RC design. It represents the stress–strain relationship in the elastic range and is used in the prediction of deflection. Out-of-range estimations for the MOE in the ...
Interpretation Procedure for Pressuremeter Tests in Sand
Publisher: American Society of Civil Engineers
Abstract: A new approach for the interpretation of pressuremeter tests in sands is proposed that permits the determination of shear strength characteristics, dilatancy properties, and shear modulus from the anlaysis of pressuremeter ...
Resistance Factors for Ductile FRP-Reinforced Concrete Flexural Members
Publisher: American Society of Civil Engineers
Abstract: To prevent damage caused by corroding reinforcement, fiber-reinforced polymer (FRP) reinforcing bars have been used in place of steel in a relatively small but increasing number of structures in civil infrastructure. A ...
Inverse Design of Single- and Multi-Rotor Horizontal Axis Wind Turbine Blades Using Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for inverse design of horizontal axis wind turbines (HAWTs) is presented in this paper. The direct solver for aerodynamic analysis solves the Reynolds-averaged Navier–Stokes (RANS) equations, where the effect of ...
Numerical Study of the Fluid Flow Around the Vertical, Deviated, and Horizontal Gas Condensate Wells From the Perspective of Fundamental Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The well performance in gas condensate reservoirs (GCRs) is an essential factor addressing the condensate recovery. A vast and growing number of studies, including numerical simulations, have compared the deliverability ...
Investigating Different Fluids and Injection Patterns on the Effect of Reservoir Rock Quality Alteration due to Swelling and Migration of Clay Minerals at Carbonate Reservoirs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nowadays, with the progress in technology, the demand for fossil fuels has increased. Therefore, improving the oil recovery from the current oil reservoir is among the crucial issues. Formation damage is a well-recognized ...
Chatter Avoidance by Spindle Speed and Orientation Planning in Five-Axis Ball-End Milling of Thin-Walled Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selecting suitable cutting conditions is crucial in maintaining chatter stability and achieving acceptable surface quality. However, the selection of a constant set of cutting parameters is not feasible due to the time-varying ...
Structural Evaluation of Tall Steel Moment-Resisting Structures in Simulated Horizontally Traveling Postearthquake Fire
Publisher: American Society of Civil Engineers
Abstract: Postearthquake fire (PEF) can result in a catastrophe even worse than the earthquake itself. Investigating the effect of PEF loads on structures is thus of paramount importance. On the other hand, because of the complexity ...
Combined Effects of Saltwater and Water Flow on Deterioration of Concrete under Freeze–Thaw Cycles
Publisher: American Society of Civil Engineers
Abstract: This article outlines the combined effects of saltwater and water flow on deterioration of concrete under freezing and thawing cycles. In order to simulate the real freezing situation that concrete usually undergoes, four ...
