Overview

Background & policy context:

The proposed work is based on the work of Bez "Modelling of traffic loads" and Bailey "Basic principles and load models for the structural safety evaluation of existing road bridges" and the report no. 515 (1995) "Load models for the safety assessment of existing structural road bridges".

The proposed project includes a continuation of the work report no. 530 (1989) "Load factors for dead load and superimposed loads to assess the structural safety of existing road bridges" and no. 556 (2001) "Load Model (40t-traffic) to assess two-lane road bridges with two-way traffic".

Objectives:

Extension of the simulation program for flexible input of traffic and bridge data.

Expansion of load models (40t and 28t vehicles) for other bridge systems and types of road.

Methodology:

Statistics, structural analysis, programming, modeling, standardization, verification of practical examples.
