RISConcrete Box Sections under Biaxial Bending and Axial Load
Publisher: American Society of Civil Engineers
Abstract: A computer program is developed for ultimate strength design of concrete box sections subjected to biaxial bending and axial load. The distribution of steel reinforcement is assumed to be symmetric in the section. In the ...

Application of Floquet Theory to On-Off Valve Controlled Pneumatic Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A periodic linear time varying (LTV) model for on-off valve controlled pneumatic actuation systems, was described in an earlier paper by the authors. Based on this LTV model formulation, Floquet’s ...
Tip Clearance Investigation of a Ducted Fan Used in VTOL Unmanned Aerial Vehicles—Part II: Novel Treatments Via Computational Design and Their Experimental Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ducted fan based vertical lift systems are excellent candidates to be in the group of the next generation vertical lift vehicles, with many potential applications in general aviation and military missions. Although ducted ...
Tip Clearance Investigation of a Ducted Fan Used in VTOL Unmanned Aerial Vehicles—Part I: Baseline Experiments and Computational Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ducted fans that are popular choices in vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAV) offer a higher static thrust/power ratio for a given diameter than open propellers. Although ducted fans provide ...
Aerodynamic Loss Characteristics of a Turbine Blade With Trailing Edge Coolant Ejection: Part 2—External Aerodynamics, Total Pressure Losses, and Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Investigation of the internal fluid mechanic losses for a turbine blade with trailing edge coolant ejection was present in Uzol et al. (2001). The current study is a detailed experimental ...
Abrasion-Porosity-Strength Model for Fly Ash Concrete
Publisher: American Society of Civil Engineers
Abstract: The durability of a concrete road to abrasive forces can be assessed effectively by measuring its abrasion resistance. This technical note reports the findings of a laboratory study including compressive strength, abrasion, ...
High Volume Fly Ash Abrasion Resistant Concrete
Publisher: American Society of Civil Engineers
Abstract: In this work, the abrasion resistance of high volume fly ash concrete was investigated. Concrete mixtures containing a large amount of fly ash replacing the cement in mass basis at 50 and 70% were prepared with various ...
High-Volume Fly Ash Concrete with High Strength and Low Drying Shrinkage
Publisher: American Society of Civil Engineers
Abstract: In this work, a laboratory investigation was carried out to evaluate the strength and particularly the shrinkage properties of concrete containing high volumes of fly ash. The concrete mixtures made with 50 and 70% replacement ...
Carbonation-Porosity-Strength Model for Fly Ash Concrete
Publisher: American Society of Civil Engineers
Abstract: The potential of a concrete for carbonation can be assessed effectively by measuring its carbonation depth using an accelerated carbonation testing. This paper reports the findings of a laboratory study including compressive ...
