RISNonlinear Finite-Element Analysis for Highway Bridge Superstructures
Publisher: American Society of Civil Engineers
Abstract: The most popular type of bridge in service today is the concrete deck on steel-girder composite bridge. A finite-element model is built to analyze the superstructure of this type of bridge under working load conditions. ...
Solutions of Complete Circular Cylindrical Shell under Concentrated Loads
Publisher: American Society of Civil Engineers
Abstract: Series solutions to the differential equations for a complete cylindrical shell under various point loads are developed. Instead of expanding the solution series in both axial and circumferential directions, the solution ...
ROAD: Interactive Geometric Design Tool for Transportation Education and Training
Publisher: American Society of Civil Engineers
Abstract: Traditionally, transportation engineering students have used engineering drawing techniques to manually lay out lines and curves over contour maps for highway geometric design. The design process requires numerous calculations ...
Optimum Design of Welded Steel Plate Girder Bridges Using a Genetic Algorithm with Elitism
Publisher: American Society of Civil Engineers
Abstract: The genetic algorithm (GA) is a general optimization technique that has some unique features that are especially suitable for structural engineering problems. This work uses a simple GA with elitism to find the optimum ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The purpose of this study is to investigate the effect of driving method and crank arrangements on the performance of a reconstructed ancient Chinese wooden horse carriage. The results demonstrate better transmission ...
Integral Equation Method for Spherical Shell under Axisymmetric Loads
Publisher: American Society of Civil Engineers
Abstract: This paper is concerned with the development of the integral equation method for the analysis of a spherical shell under axisymmetric loads. The governing equations of shell are traditionally described as a set of two ...
Analysis and Optimal Design of Spherical Shells under Axisymmetric Loads
Publisher: American Society of Civil Engineers
Abstract: In a companion paper the integral equations for a spherical shell have been developed. This paper is concerned with the engineering applications of the integral equation method. A structure is selected to demonstrate how ...
Effect of Initial Curvature on Natural Frequency of Thin Plate on Hinge Supports
Publisher: American Society of Civil Engineers
Abstract: This study investigates the influence of initial curvature on the dynamic behavior of a hinge‐supported thin plate. The large‐deflection theory is used to determine the mid‐plane forces produced by the deflection and the ...
Effect of the Honeycomb Tip With Injection on the Aerodynamic Performance in a 1.5-Stage Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three kinds of rotor tip configurations have been investigated numerically in the LISA 1.5-stage turbine, including the flat tip, the honeycomb tip, and the honeycomb tip with injection. The effect of the cavity depth and ...
Experimental and Numerical Study of Honeycomb Tip on Suppressing Tip Leakage Flow in Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the effect of a novel honeycomb tip on suppressing tip leakage flow in turbine cascade has been experimentally and numerically studied. Compared to the flat tip cascade with 1%H blade height, the relative ...
