Analysis of the Shear Behavior of Stubby Y-Type Perfobond Rib Shear Connectors for a Composite Frame Structure
Shear connectors are used in steel beam-concrete slabs of composite frame and bridge structures to transfer shear force according to design loads. The existing Y-type perfobond rib shear connectors are designed for girder slabs of composite bridges. Therefore, the rib and transverse rebars of the conventional Y-type perfobond rib shear connectors are extremely large for the composite frames of ...
متن کاملEffects of Rib Shapes on Heat Transfer Characteristics of Turbulent Flow of Al2O3-Water Nanofluid inside Ribbed Tubes
In this paper, convection heat transfer of Al2O3-water nanofluid turbulent flow through internally ribbed tubes with different rib shapes (rectangular, trapezoidal and semi-circular) is numerically investigated. For each rib shape, the optimum geometric ratio and volume fraction were calculated using entropy generation minimization technique. The governing equations in...
متن کاملA new vascular ring connector in surgery for aortic dissection.
OBJECTIVE To improve the surgical results of aortic dissection, we used a novel vascular ring connector for anastomosis. METHODS The vascular ring connector is a titanic ring used as a stent in the vascular graft to achieve a quick, blood-sealed, and sutureless anastomosis. From November 2007 to December 2008, 19 consecutive patients (age range 36-77 years; 16 male and 3 female) with aortic d...
متن کاملIn vitro microbiology studies on a new peritoneal dialysis connector.
OBJECTIVE We evaluated the ability of a recently developed peritoneal dialysis (PD) connector to prevent the risk of bacterial transfer to the fluid path after simulated touch and airborne contamination. METHODS Staphylococcus epidermidis ATCC1228 and Pseudomonas aeruginosa ATCC27853 strains were used. For touch contamination, 2 μL of a standardized inoculum [1×10(8) colony-forming units (CFU...
متن کاملNew Implosive Connector Technology for High Voltage Conductors
A new method of splicing high voltage conductors has been making its way into the electrical utility industry, displacing the conventional method at an ever-increasing pace. While conventional technology uses a hydraulic compression process, this new method uses implosive energy to make the splice. This paper describes the basic principals behind this new technology and compares the implosive m...
