Plated Structures

Module aims

  • To understand the behaviour and design of plated steel structures.

Learning outcomes

By the end of the course, students should be able to: 

  • Understand the elastic buckling and post-buckling of plates under in-plane loading.
  • To design stiffened compression flanges and plate girders.

Teaching methods

A mixture of lectures and tutorials focusing on:

  • Large deflection plate theory; laterally loaded plates; elastic post-buckling of axially compressed perfect and imperfect plates. 
  • Collapse of plates in compression: effective width concept, effect of imperfections and residual stresses; code design. 
  • Stiffened plates in compression and bending: elastic buckling analysis, beam-column behaviour orthotropic action, local and overall buckling; design of compression flanges, slenderness limitations for stiffeners. 
  • Plate girders: critical buckling of plates in shear, tension field theory; design of plate girders under bending and shear. 
  • Box girders: plates under combined loading, web panel design, treatment of web stiffeners.
