RISFlexural, Compressive Arch, and Catenary Mechanisms in Pseudostatic Progressive Collapse Analysis
Publisher: American Society of Civil Engineers
Abstract: Progressive collapse has drawn significant attention from researchers because of its potential to inflict severe damage and casualty. Much research has focused on simulation techniques for collapse, but comparatively little ...
A Comprehensive Hydrodynamics-Salinity-pH Model for Analyzing the Effects of Freshwater Withdrawals in Calcasieu Lake and Surrounding Water Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study is a continuation of the authors' previous works on hydrodynamics and sediment transport modeling for Calcasieu Lake area (located in southwest Louisiana) (Zhang, N., Zheng, Z. C., and Yadagiri, S., 2011, “A ...
Numerical and Experimental Investigation on Vortex-Induced Vibration Suppression of a Self-Anchored Suspension Bridge with a Central-Slotted Box Girder
Publisher: American Society of Civil Engineers
Abstract: In this study, the vortex-induced vibration (VIV) performance, mechanism, and control of a self-anchored suspension bridge with the central-slotted box girder (CSBG) under the operating wind velocity of the bridge were ...
Analysis of the Characteristics of Pseudo-Resonance and Anti-Resonance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the analytical expressions of the dynamic compliances of both undamped and damped cantilever beams are found by the transfer funtion method. From these solutions, the phenomenon ...
A Fully Enclosed Wave Energy Converter and Effects of Cable-Based Power Take-Off System on Power Absorption
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Existing wave energy converters (WECs) are limited by high unit energy costs, narrow bandwidths, and vulnerability to seawater corrosion, making it difficult for wave energy to compete with solar and wind energy. This paper ...
Research on Creep Behavior of Three-Point Bending Specimen With Fixed Constraints at the Large Deformation Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-point bending specimen with fixed constraints is a novel small specimen test technique, which can simultaneously obtain creep deformation and creep fracture data. However, the current research only focused on the ...
Combustion Instabilities With Different Degrees of Premixedness in a Separated Dual-Swirl Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of premixedness degrees on combustion instabilities of separated dual-swirl flames have been investigated experimentally in the Beihang Axial Swirler Independently Stratified (BASIS) burner. The degree of ...
Experimental and Numerical Investigation on Filling Roll Bending of Aluminum Alloy Integral Panel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Integral panels are widely used in aerospace industries. A filling roll bending process is proposed to form integral panels. Filling roll bending experiments of aluminum alloy integral panels ...
The Effect of Stratification Ratio on the Macrostructure of Stratified Swirl Flames: Experimental and Numerical Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper reports experimental and numerical analyses of the macrostructures featured by a stratified swirling flame for varying stratification ratio (SR). The studies are performed with the Beihang Axial Swirler ...
A Rapid Algorithm of Fundamental Frequency for the Freestanding Pylon of Suspension Bridges
Publisher: American Society of Civil Engineers
Abstract: The combination of Rayleigh’s energy method and Southwell’s frequency composition method denoted the fundamental vibration frequencies of the freestanding pylon of suspension bridges as the composition of several subsystem ...
