RISAdaptive Frequency Green Light Optimal Speed Advisory Based on Deep Reinforcement Learning
Publisher: American Society of Civil Engineers
Abstract: The Green Light Optimal Speed Advisory (GLOSA) system suggests speeds to vehicles to assist them pass intersections during green intervals. In application, drivers can ultimately decide whether to change speed based on ...
Analytical Solution of Terzaghi’s Ground Arch Model for Loads on Circular Tunnels
Publisher: American Society of Civil Engineers
Abstract: To date, the important problem of Terzaghi’s ground arch model in 1946 has not been solved for loads on circular tunnels. This study comprehensively presented a general analytical solution of Terzaghi’s ground arch model ...
Numerical Modeling of Shear Behavior of Reinforced Concrete Pile Caps
Publisher: American Society of Civil Engineers
Abstract: The application of bending theory based methods and strut-and-tie models for the design of pile caps to resist shear is still a subject of debate, with the latest Eurocodes permitting both methods but not giving much ...
Efficient Two-Way Shear Grillage Model Solution for Bridge RC Four-Pile Caps under Wall Loading
Publisher: American Society of Civil Engineers
Abstract: Reinforced concrete four-pile caps under wall loading occur in heavily loaded foundations in bridge construction. The failure mode of shear across the full width of the cap may occur in these deep structural elements. A ...
Dynamics of Frozen Orbit and Its Critical Case in the Zonal Problem
Publisher: ASCE
Abstract: This paper investigates the dynamical behaviors of Earth frozen orbits including the critical inclination orbit in the zonal problem with terms of perturbations up to J15. From the mean element theory, an analytical expansion ...
Low-Thrust Station-Keeping Strategy toward Exploiting the Resonances in the Geostationary Region
Publisher: ASCE
Abstract: Low-thrust propulsion systems are widely used in space missions due to their high specific impulse and reduced propellant consumption. However, current research focuses on eliminating drifts in low-thrust maneuvers, resulting ...
When Do Mid-Project Reviews (MPRs) Deliver the Greatest Project Benefits? Comparative Analysis of Australian Review Outcomes
Publisher: American Society of Civil Engineers
Abstract: Increasing infrastructure investment necessitates the application of reference class forecasting approaches to reduce bias involved in decisions to achieve better outcomes. Widely adopted internationally, mid-project reviews ...
Behavior of a Stiff Clay behind Embedded Integral Abutments
Publisher: American Society of Civil Engineers
Abstract: Integral bridges can significantly reduce maintenance and repair costs compared with conventional bridges. However, uncertainties have arisen in the design as the soil experiences temperature-induced cyclic loading behind ...
Experimental Study and Analysis on Rotational Behavior of Bamboo Scrimber Beam-to-Column Bolted Connections
Publisher: ASCE
Abstract: This paper studies the rotational behavior of beam-to-column bolted connections in bamboo scrimber structures. Three types of beam-to-column connections, including bolted connections with outer-clamping steel plates, bolted ...
Satellite Constellation Reconfiguration Using Surrogate-Based Optimization
Publisher: ASCE
Abstract: The reconfiguration of a constellation with several faulty satellites concerns performance improvements in multiple fields, which can be regarded as a multiobjective optimization (MOO) problem. In the optimization design, ...
