Adaptive Analysis for Random Response of Wind–Vehicle–Bridge System Based on a Hybrid Deep-Learning Method
Publisher: American Society of Civil Engineers
Abstract: AbstractA hybrid method for random response analysis of a wind–vehicle–bridge (WVB) system
is presented. The method employs the gated recurrent unit (GRU) network to predict
dynamic responses of the WVB system, enhanced ...
Improved Spectral Representation Method for the Simulation of Stochastic Wind Velocity Field Based on FFT Algorithm and Polynomial Decomposition
Publisher: American Society of Civil Engineers
Abstract: For the simulation of fluctuating wind velocity field with n processes, the existing spectral representation method requires a total of n(n+1)/2 executions of the fast Fourier transform (FFT) algorithm. This requirement ...
Numerical Simulation of Wind Fields at the Bridge Site in Mountain-Gorge Terrain Considering an Updated Curved Boundary Transition Section
Publisher: American Society of Civil Engineers
Abstract: To investigate the characteristics of wind fields at the bridge site in mountain-gorge terrains more accurately and rationally, an updated curved boundary transition section (BTS) was proposed in this study. The flow ...
Soil-Pile-Quay Wall System with Liquefaction-Induced Lateral Spreading: Experimental Investigation, Numerical Simulation, and Global Sensitivity Analysis
Publisher: American Society of Civil Engineers
Abstract: Extensive damage to offshore and port structures supported on piles behind a quay wall has been frequently reported as a result of soil liquefaction and lateral spreading in earthquakes. This study aims to explore the ...
Reliability Analysis of Road Vehicle and Train-Running Safety When Meeting on a Single-Level Rail-cum-Road Bridge under Crosswind Conditions
Publisher: American Society of Civil Engineers
Abstract: Abstract Strong crosswinds present substantial safety challenges for road vehicles and trains,
especially on long-span bridges. Single-level rail-cum-road bridges, which support
both road and rail traffic on a shared deck, ...
