Probabilistic assessment and sensitivity analysis of existing concrete bridge via surrogate modeling

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Seismic Vulnerability assessment of concrete railway bridge using nonlinear analyses

Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is bare...

Global Sensitivity Analysis-Enhanced Surrogate (GSAS) Modeling for Reliability Analysis

Department of Civil and Environmental Engineering Vanderbilt University, Nashville, Tennessee 37235, USA Abstract An essential issue in surrogate model-based reliability analysis is the selection of training points. Approaches such as efficient global reliability analysis (EGRA) and adaptive Kriging Monte Carlo simulation (AK-MCS) methods have been developed to adaptively select training points...

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

Delamination and concrete quality assessment of concrete bridge decks using a fully autonomous RABIT platform

One of the main causes of a limited use of nondestructive evaluation (NDE) technologies in bridge deck assessment is the speed of data collection and analysis. The paper describes development and implementation of the RABIT (Robotics Assisted Bridge Inspection Tool) for data collection using multiple NDE technologies. The system is designed to characterize three most common deterioration types ...
