The present section of Deliverable D.4.3 is dedicated to the static and fatigue assess-ment of old metal bridges. It forms the basis of the Chapter 7 guideline developed in work package 4 (WP4) “Guideline for Load and Resistance Assessment of Existing European Railway Bridges”. This section is divided into four parts related to the four research activities of the WP4 metal subgroup:

– Analysis of material properties of existing metal railway bridges, – Fatigue of riveted structure,

– Updated assessment methods for riveted structures,

– Enhanced non destructive techniques for inspecting riveted structures.
