RIS<i>Anelosimus eximius</i> Colony Algorithm and Its Application to Celestial Doppler Difference Velocimetry
Publisher: American Society of Civil Engineers
Abstract: To accelerate the convergence rate of high-dimensional optimization problems, inspired by the cooperative hunting process of spider colonies named Anelosimus eximius, a new A. eximius colony algorithm (AECA) was proposed ...
Temperature Prediction of Flat Steel Box Girders of Long-Span Bridges Utilizing In Situ Environmental Parameters and Machine Learning
Publisher: ASCE
Abstract: Design, construction, and maintenance of large-span bridges require an accurate assessment of the temperature field in flat steel box girders (FSBGs). While this field is controlled by various environmental (meteorological) ...
Automobile Exhaust–Purifying Performance of Tourmaline-Modified Asphalt Concrete
Publisher: American Society of Civil Engineers
A UAV Allocation Method for Traffic Surveillance in Sparse Road Network
Publisher: American Society of Civil Engineers
Abstract: Unmanned aerial vehicle (UAV) technology was introduced in traffic surveillance in sparse road networks, and a UAV allocation method with/without UAV continuous flight distance constraint was proposed. First, the method ...
Fatigue Performance of Cracked Tubular T Joints under Combined Loads. I: Experimental
Publisher: American Society of Civil Engineers
Abstract: Experimental fatigue tests were carried out on three tubular T joints having the same geometrical parameters subjected to in-plane bending (IPB) only, combination of IPB and out-of-plane bending (OPB), and a combination ...
Damage Detection in Long Suspension Bridges Using Stress Influence Lines
Publisher: American Society of Civil Engineers
Abstract: Numerous long-span cable-supported bridges have been built throughout the world in recent years. These bridges begin to deteriorate once built and continuously accumulate damage during their long service life. The growing ...
Complexification-Averaging Analysis on a Giant Magnetostrictive Harvester Integrated With a Nonlinear Energy Sink
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study aims to investigate the steady-state response regimes of a device comprising a nonlinear energy sink (NES) and a giant magnetostrictive energy harvester utilizing analytical approximation. The ...
Joint Distribution of Wind Speed, Wind Direction, and Air Temperature Actions on Long-Span Bridges Derived via Trivariate Metaelliptical and Plackett Copulas
Publisher: ASCE
Abstract: Comprehensive bridge design should consider simultaneous actions of wind and temperature. The current load combination method of directly superposing extreme wind and temperature actions ignores the correlation between ...
Analysis on Road Traffic–Status Discrimination Results at Different Time Intervals
Publisher: ASCE
Abstract: To estimate traffic status on an urban road accurately and determine the appropriate traffic-status evaluation interval, this research introduces a method based on the theory of set-pair analysis, and takes the number of ...
Bridge Influence Line Identification Based on Regularized Least-Squares QR Decomposition Method
Publisher: American Society of Civil Engineers
Abstract: The bridge influence line is an important tool to study the bridge response under moving loads and contains tremendous structural information. Structural deterioration during the bridge’s service life will induce variation ...
