Double-Stage Friction-Based Self-Centering Dampers: Proof-of-Concept Tests and Seismic Control Analysis
Publisher: American Society of Civil Engineers
Abstract: Due to the relatively low damping and sharp stiffness change, friction-based self-centering dampers are less effective in controlling peak interstory drift (PID) and peak floor acceleration (PFA). To address these concerns, ...
Gaussian Distribution–Based Control Vector Parameterization Method for Constrained Hypersonic Vehicle Reentry Trajectory Optimization
Publisher: ASCE
Abstract: This study proposes a Gaussian-discretization control vector parametrization (CVP) algorithm to improve the reentry trajectory optimization accuracy of a hypersonic vehicle (HV) with a complex path and terminal state ...
Seismic Design and Performance Evaluation of a Triple-Column Bent Bridge Retrofitted with Buckling-Restrained Shape Memory Alloy Dampers
Publisher: American Society of Civil Engineers
Abstract: In seismic prone regions, many old bridges deserve retrofitting measures to improve their seismic resilience. The recently proposed buckling-restrained shape memory alloy (SMA) dampers, which can maintain axial resistance ...
Aesthetics and Torsional Rigidity Improvements of a Triple-Cable Suspension Bridge by Uniform Distribution of Dead Loads to Three Cables in the Transverse Direction
Publisher: ASCE
Abstract: Suspension bridges with three cable planes provide an excellent solution to the suspension bridges’ downwarp problem with ultrawide decks, which implies their enormous demand and popularization prospect in the engineering ...
Anti-Icing Properties of a Polyurethane Superhydrophobic Coating on Asphalt Pavement
Publisher: ASCE
Abstract: Snow and ice accumulation on asphalt pavement can increase the risk of traffic issues. The traditional method of removing snow and ice manually or mechanically from the road surface is time-consuming and labor-intensive. ...
