This model is of a 60 m span steel truss footbridge, curved in elevation, constructed with square hollow sections for the bottom boom members and circular hollow sections for the top boom and bracing. The deck spans between the two bottom boom members and is braced diagonally with angles.
The material used throughout is structural steel with an elastic modulus of
210kN/mm2, a shear modulus of 81kN/mm2 and a weight density of 77kN/m3. (Note that the 75x75x12 angle is to have a density of 78kN/m3
