RISPlastic-Damage Cap Model with Crack Closure Behavior for Concrete Modeling
Publisher: ASCE
Abstract: A new isotropic plastic-damage cap model of concrete is proposed in this study to overcome the limitations (e.g., crack closure behavior) of the existing continuous surface cap (CSC) model in the hydrocode LS-DYNA. ...
Optimization of Periodic Train Schedule with Flexible Train Composition during Off-Peak Periods for Urban Rail Transit
Publisher: American Society of Civil Engineers
Abstract: Focusing on the insufficient passenger demand during off-peak periods in urban rail transit, a new train operation mode with flexible train composition considering trains couple/decouple at intermediate stations is proposed. ...
Optimal Transit Route Network Design Problem with Variable Transit Demand: Genetic Algorithm Approach
Publisher: American Society of Civil Engineers
Abstract: This paper uses a genetic algorithm to systematically examine the underlying characteristics of the optimal bus transit route network design problem (BTRNDP) with variable transit demand. A multiobjective nonlinear mixed ...
Using a Simulated Annealing Algorithm to Solve the Transit Route Network Design Problem
Publisher: American Society of Civil Engineers
Abstract: This paper uses a simulated annealing algorithm to solve the optimal bus transit route network design problem (BTRNDP) at the distribution node level. A multiobjective nonlinear mixed integer model is formulated for the ...
Extraction of Bridge Frequencies from a Moving Test Vehicle by Stochastic Subspace Identification
Publisher: American Society of Civil Engineers
Abstract: The technique for extracting bridge frequencies from a moving vehicle was proposed only recently. However, its efficacy may be reduced by road-surface roughness. To this end, the stochastic subspace identification (SSI) ...

Residual Capacity of Axially Loaded Circular RC Columns after Lateral Low-Velocity Impact
Publisher: American Society of Civil Engineers
Abstract: RC bridge columns that are at risk for collision loading must be designed for lateral impact load. Because bridge columns must also support axial loads, evaluating the residual axial capacity and collapse risk of impact-damaged ...

Deployment Dynamics and Control of a Hub-Spoke Tethered Satellite Formation Using Combined Arbitrary Lagrange-Euler and Referenced Nodal Coordinate Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel modeling framework combining arbitrary Lagrange-Euler and referenced nodal coordinate formulation (ALE-RNCF) is proposed for deployment dynamics and control of a hub-spoke tethered satellite formation. The ALE-RNCF ...
Behavior and Analysis of Simply Supported Bridges under Vessel Side Collisions: Implications from Collapse of the Taiyangbu Bridge
Publisher: ASCE
Abstract: On July 7, 2020, the Taiyangbu Bridge crossing the Changjiang River was hit by a barge loaded with sand, resulting in the collapse of the main span. Such side collisions are seldomly investigated in previous studies. To ...
