RISStudying the Optimal Layout of Topological Graphs to Facilitate the Automatic Sketching of Kinematic Chains
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sketching of kinematic chains is important in the conceptual design of mechanisms. In general, the process of sketching kinematic chains can be divided into two steps, namely sketching topological graphs and converting ...

Method for Identifying Bridge Collapse Pattern: Theoretical Analysis
Publisher: American Society of Civil Engineers
Abstract: A method for identifying the collapse patterns of continuous girder bridges and single-pylon cable-stayed bridges was developed on the basis of the limit analysis theorem. First, collapse models of continuous girder bridges ...
Method for Identifying Bridge Collapse Patterns: Analysis of Cases
Publisher: American Society of Civil Engineers
Abstract: A method is proposed to identify bridge collapse patterns based on the limit analysis theorem. The Erchong Floodway single-pylon cable-stayed bridge in Taiwan and the Kap Shui Mun twin-pylon cable-stayed bridge in Hong ...
Simulation of Atmosphere Boundary Layer by Using Wedges and Rough Elements Technique
Publisher: American Society of Civil Engineers
Abstract: Based on the technique that using wedges and roughness elements to simulate the atmospheric boundary layer, barriers acting as vortex generators were used to effectively increase turbulence intensity on top of wind tunnel. ...
Wind Tunnel Test of Aerodynamic Optimization Measures for Flutter Stability of Super Long-span Bridge with Truss Girder
Publisher: American Society of Civil Engineers
Abstract: Taken a grand long-span suspension bridge with truss girder for example, the influences of various aerodynamic controlling measures such as central-slotting in bridge deck plate, apron board and pneumatic winglets on the ...
Effects of Hydrothermal Modification on Sulfur Release of Low-Quality Coals During Thermal Transformation Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the effects of hydrothermal modification on sulfur-containing pollutants, such as sulfur dioxide (SO2) and carbonyl sulfide (COS), during coal pyrolysis and combustion, have been investigated. Three typical ...
Experimental Study of a Wind Field in a Long-span Bridge Site Located in Mountainous Valley Terrain
Publisher: American Society of Civil Engineers
Abstract: The Baling River Bridge is a long-span bridge located in a special mountainous area. The site has a very complicated wind field that is representative of many cases in west China. A terrain model that simulates the practical ...
Numerical Investigation of Sediment Transport of Sandy Beaches by a Tsunami-Like Solitary Wave Based on Navier–Stokes Equations

Abstract: To improve our current understanding of tsunami-like solitary waves interacting with sandy beach, a nonlinear three-dimensional numerical model based on the computational fluid dynamics (CFD) tool OpenFOAM® is first ...
The Impacts of Atmospheric and Surface Parameters on Long-Term Variations in the Planetary Albedo
Publisher: American Meteorological Society
Abstract: AbstractPlanetary albedo (PA; shortwave broadband albedo) and its long-term variations, which are controlled in a complex way by various atmospheric and surface properties, play a key role in controlling the global and ...
