Correct evaluation of the behaviour of highway bridges under heavy traffic loading is ex-tremely important both for the enhancement of design techniques, and also for the assessment of existing infrastructure. It is widely accepted that shortfalls exist in the determination of the traffic load which the bridge may be required to support during its expected lifetime due to in-adequate consideration of amongst other factors, the dynamic interaction between the bridge structure and the heavy vehicles crossing it. Since it is the overall objective of this deliverable to combine lifetime static load effect values, with realistic dynamic amplification factors (to obtain an overall total lifetime load effect) there are two distinct parts: 1) The calculation of bridge static load effect due to site-specific traffic flow, which is dis-cussed in subtask 2.1.1 (Deliverable D08) along with the resultant assessment of bridge life-time static load effect, and the selection of those loading events that are deemed critical (stati-cally). Examples on how to determine these bridge traffic load models using Weigh-In-Motion (WIM) data and their configuration when using data from Central European countries are pro-vided in subtask 2.1.1 on bridge traffic load monitoring. This subtask has also compared re-sults between data from Western and Central European countries. 2) Deliverable D10 focuses on the assessment of the levels of dynamic interaction occurring between a bridge and its associated vehicular traffic. This analysis incorporates a review of those recommendations given in current design/assessment codes for dynamic allowance. Then, the procedure to obtain a site-specific dynamic amplification factor using theoretical simulations and available experimental data is described.
