Importance of the tail in truck weight modeling for bridge assessment

O'Brien, Eugene J. ; Enright, Bernard ; Getachew, Abraham (American Society of Civil Engineering (ASCE), 2010-03)

To predict characteristic extreme traffic load effects, simulations are sometimes performed of bridge loading events. To generalize the truck weight data, statistical distributions are fitted to histograms of weight ...
Simplifed site-Specific traffic load models for bridge assessment

Getachew, Abraham ; O'Brien, Eugene J. (Taylor & Francis, 2007-12)

Traffic load is identified as one of the greatest sources of uncertainty in the assessment of bridges. In recent years, simulation techniques, using measured traffic data, have been used to predict the characteristic traffic ...
