Long-Run Traffic Simulations for Multi-Lane Road Bridges

This paper describes the methodologies undertaken in the simulation of long-run traffic load models for two multilane road bridges in the Netherlands. These were developed for use in predictive

Towards actual brazilian traffic load models for short span highway bridges

New live load models for highway bridge design in Brazil are under development by assembling real traffic database, traffic simulations, analytical-numerical modeling of the dynamic interaction

Highway Bridge Traffic Loading

Emphasis is given to the promising application of traffic microsimulation to long-span bridge loading, combined with a probabilistic approach based on the extreme value theory, to compute site-specific characteristic loading values.

Simulation of Traffic Loading on Long Span Bridges

Existing long span load models have typically been developed using a number of conservative assumptions, and as such are more applicable to the design of new bridges rather than the assessment of

Validation of Scenario Modelling for Bridge Loading

Accurate estimates of characteristic bridge load effects are required for efficient design and assessment of bridges, and long-run traffic simulations are an effective method for estimating the

Using Weigh-in-Motion Data to Determine Aggressiveness of Traffic for Bridge Loading

This paper presents results based on the analysis of an extensive database of weigh-in-motion (WIM) data collected at five European highway sites in recent years. The data are used as the basis for a

Single and Multiple Presence Statistics for Bridge Live Load Based on Weigh-in-Motion Data

The results show that the general tendency of the occurrence of all multiple presence events is to increase as the truck volume increases and that the daily truck volume considerably affects the multiple presence statistics for all load patterns.



Stochastic Model for Multilane Traffic Effects on Bridges

This paper presents a more general theoretical stochastic traffic model, able to reproduce actual traffic, but to account for such traffic interactions as well, and can be used in all cases where sophisticated evaluation of real traffic effects is required.

Monte Carlo simulation of extreme traffic loading on short and medium span bridges

The accurate estimation of site-specific lifetime extreme traffic load effects is an important element in the cost-effective assessment of bridges. A common approach is to use statistical

Multiple Presence Statistics for Bridge Live Load Based on Weigh-in-Motion Data

A study was done to determine truck load spectra for bridges in New Jersey with emphasis on multiple truck presence statistics. Truck weight data were collected by the New Jersey Department of


The results of a study are described which aimed at the derivation of a traffic load model for the design of road bridges. Attention is given to the Ultimate Limit State, the Serviceability Limit

Live load model for highway bridges

Comparison Of Traffic Load Models Based On Simulation And Measured Data

It is shown that, although simulated truck traffic may adequately predict near-future levels, simulation does not reflect the variability associated with far-future estimates.

Headway modelling for traffic load assessment of short to medium span bridges

Site-specific assessment of the loading to which existing bridges are subject has considerable potential for saving on rehabilitation and replacement costs of the bridge stock. Monte Carlo

Importance of the Tail in Truck Weight Modeling for Bridge Assessment

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

Protocols for Collecting and Using Traffic Data in Bridge Design

This report provides a set of protocols and methodologies for using available recent truck traffic data to develop and calibrate vehicular loads for load and resistance factor design (LRFD)

Multivariate Simulation and Multimodal Dependence Modeling of Vehicle Axle Weights with Copulas

A transformation invariant approach using copula functions is proposed for the multivariate simulation of dependent axle weights of different vehicle classes and is found to be in very good agreement with the observed data.
