Northam railway bridge, an unusual bridge in southampton
Northam Bridge in Southampton dates from 1908. It has an unusual layout, with one main girder on one side and two on the other. Its structure is also unusual, consisting of twin lattice girder webs with members of varying size. The history of the bridge in the context of the London and South Western Railway is presented together with a detailed breakdown of its structure. A finite element analysis of the structure was carried out to examine the load path through the highly redundant web. The structural response was compared with the behaviour of a simple truss and a plate girder. It was shown that the bridge is generally sound even for 40 t vehicle loading, although the deck supports give some cause for concern.

Abstract
Northam Bridge in Southampton dates from 1908. It has an unusual layout, with one main girder on one side and two on the other. Its structure is also unusual, consisting of twin lattice girder webs with members of varying size. The history of the bridge in the context of the London and South Western Railway is presented together with a detailed breakdown of its structure. A finite element analysis of the structure was carried out to examine the load path through the highly redundant web. The structural response was compared with the behaviour of a simple truss and a plate girder. It was shown that the bridge is generally sound even for 40 t vehicle loading, although the deck supports give some cause for concern.
