RISCoupled Plasticity and Damage Constitutive Model Considering Residual Shear Strength for Shales
Publisher: ASCE
Abstract: Shales are the most common materials on the Earth's surface that are frequently encountered in various energy, environmental, and engineering applications. Numerically predicting the mechanical behavior of shales is of ...
Implementation Challenges of State-Led Redevelopment in Shrinking Cities: Case Study of Shantytown Redevelopment in Yichun, Northeast China
Publisher: ASCE
Abstract: Unlike shrinking cities in Western countries enduring prolonged disinvestment due to market liberalism, some of their counterparts in Northeast China are undergoing drastic redevelopment under state capitalism. However, ...
Ground Control Monitoring in Backfilled Strip Mining under the Metropolitan District: Case Study
Publisher: American Society of Civil Engineers
Abstract: Ground subsidence and coal gangue induced by mining activities could significantly influence the nearby environment. To allow strict public scrutiny of mining under the metropolitan district, coal gangue backfill has been ...
Exploring Thermal Regulation in Low-Pressure Adsorption Tanks for CO2 Compression Energy Storage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Compressed CO2 energy storage (CCES) presents a viable alternative to compressed air energy storage (CAES), offering distinct advantages. However, the storage of low-pressure CO2 poses a notable challenge. We ...
Numerical Modeling of Fully Grouted Rockbolts Reaching Free-End Slip
Publisher: American Society of Civil Engineers
Abstract: In this study, numerical simulation was conducted to model the behavior of rockbolts with free-end slip in tension. A nonlinear bond–slip relationship was input to the numerical model to represent the interaction mechanism ...
Internal Wind Pressures and Buckling Behavior of Large Cylindrical Floating-Roof Tanks Under Various Liquid Levels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, two practical large cylindrical floating-roof tanks with diameters of 60 m and 100 m are selected as research objects. Wind pressures on the internal wall of tank shells under various liquid levels are ...
How Income and Risk Preferences Shape Travel Choices under Uncertainty: Insights from a Multiround Game
Publisher: American Society of Civil Engineers
Abstract: With the development of multimodal transportation systems, travelers face various choices to decide how to travel from one place to another. Given uncertainty, former experience, and individual characteristics such as ...
Finite-Element Model Modification for Investigating the Dynamic Behavior of Fire-Exposed Reinforced Concrete Beams with Corrosion
Publisher: American Society of Civil Engineers
Abstract: To obtain a precise finite-element model (FEM) for analyzing the dynamic response of corroded beams at high temperatures, a stepwise FEM modification strategy is proposed based on the improved extreme learning machine. ...
Design and Analysis of a New Pressure Relief Valve for Oil-Immersed Electrical Equipment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Internal arcing in oil-immersed electrical equipment is inevitable and of great danger. Transient overpressure should be released by protectors quickly and controllably. Currently available pressure relief valves cannot ...
Experimental Study on Load-Transfer Mechanism of Rockbolts Using Fiber Optic and Strain Gauge Monitoring
Publisher: American Society of Civil Engineers
Abstract: As a cost-effective rock-supporting method, rockbolts have been widely used in geotechnical and mining engineering. Better understanding the load-transfer mechanism of rockbolts is of great importance for improving the ...
