RISNumerical Analysis of Thermo-Hydro-Mechanical Coupling of Diversion Tunnels in a Seasonally Frozen Region
Publisher: ASCE
Abstract: A thermo-hydro-mechanical (THM) coupling model that considers phase transition and frost heaving was developed for a diversion tunnel in a seasonally frozen region. Based on the partial differential equation defined by ...
Experimental and Numerical Study of the Performance of Self-Centering Frame Structures Subjected to Debris-Flow Impacts
Publisher: ASCE
Abstract: To investigate the performance of self-centering RC frame structures subjected to debris-flow impacts, a series of debris-flow impact tests of a traditional RC frame structure (TF) and a self-centering RC frame structure ...
Long-Term Deformation of Highway Subgrade under Coupling Effect of Traffic Load and Drying–Wetting Cycles
Publisher: ASCE
Abstract: Subgrade long-term deformation was investigated by taking the effects of both traffic load and drying–wetting cycles into consideration on the basis of numerical calculation and laboratory experiments. The total subgrade ...
Experimental Investigation of the Seismic Behavior of Low-Yield-Point Corrugated Steel Plate Dampers
Publisher: ASCE
Abstract: In this paper, an innovative low-yield-point corrugated steel plate damper (LCSPD) was proposed, which consisted of two corrugated webs as the shear component and two outer corrugated plates as the bending component. Four ...
Seismic Performance of M-Section Cold-Formed Thin-Walled Steel-Reinforced Concrete Wall
Publisher: ASCE
Abstract: To overcome the shortcomings of traditional shear walls, structure systems have been proposed and investigated. One such structure system is a steel-reinforced concrete shear wall, which has certain desirable properties ...
An Experimental Study on Heat Transfer Enhancement of Non Newtonian Fluid in a Rectangular Channel With Dimples/Protrusions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dimple and protrusion play important roles in the heat transfer enhancement and flow characteristic in cooling channels, which widely employed within electronic cooling systems. NonNewtonian fluid has significant differences ...
Analytical Model to Predict Dynamic Responses of Railway Subgrade due to High-Speed Trains Considering Wheel–Track Interaction
Publisher: American Society of Civil Engineers
Abstract: In this paper, a full vehicle–track–ground coupling model is presented to evaluate the dynamic response of the subgrade due to high-speed trains. The vehicle was modeled as a multibody. The track was considered as an Euler ...
Flow and Heat Transfer Characteristics in Channels With Groove–Protrusions and Combination Effect With Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Passive flow control and heat transfer enhancement technique has become an attractive method for device internal cooling with low resistance penalty. In the present paper, the flow and heat transfer characteristics in the ...
Experimental Study on Performance of Frame Structure Strengthened with Foamed Aluminum under Debris Flow Impact
Publisher: ASCE
Abstract: It is well recognized that debris flow is a threatening natural hazard that can apply a large impact force on building structures. To increase structural safety, it is imperative to understand the structural performance ...
Semianalytical Solution for Dynamic Responses of Railway Track System on Unsaturated Poroelastic Half-Space Subjected to Moving Trainload
Publisher: ASCE
Abstract: A track-unsaturated ground model was proposed to study the dynamic responses of the unsaturated subgrade induced by moving trainloads. The subgrade was modeled by an unsaturated poroelastic half-space, and the railway track ...
