Abstract: Axial fans with a small hub-to-tip diameter ratio (HTR) are widely used in industry, especially for cooling and ventilation purposes. The optimization of their aerodynamic performance is important, for which the vortex ...
Integrated Control of Thermally Induced Vibration and Quasi Static Deformation of Space Truss
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic vibration and quasistatic deformation will occur simultaneously for flexible space structures subjected to sudden thermal loads. In this paper, the integrated controller based on modified positive position feedback ...
Effects of Cross-Sectional Size and Shape on the Longitudinal Tensile and Anchoring Properties of CFRP Cables
Publisher: American Society of Civil Engineers
Abstract: Carbon fiber–reinforced polymer (CFRP) is very suitable for use as a prestressed cable and can replace conventional steel cables in cable roofs. In engineering practice, the anchoring length increases rapidly as the ...
Experimental and Numerical Analysis of Steel-Block Shear Connectors in Assembled Monolithic Steel–Concrete Composite Beams
Publisher: American Society of Civil Engineers
Abstract: To study the shear behavior of the steel-block shear connector (SBSC) welded on a steel beam, eight push-out experiments were conducted, including two specimens with cast-in-place (CIP) concrete decks and six specimens ...
Cold-Formed Steel Shear Wall Using Corrugated Steel Sheathing with Slits
Publisher: American Society of Civil Engineers
Abstract: Recent research shows that shear walls with corrugated steel sheathing demonstrate high strength and high initial stiffness but low ductility. This paper presents an experimental study and numerical simulation aimed at ...
