The aim of this experiment is to examine how structures behave in reality and to see how the physical experiment compares with theoretical outcomes. The apparatus comprises a loading rig into which has been clamped a model portal frame made of a 6 mm&'710,2 mild steel section. The loading system is provided by a system of pulleys and strings which are designed to apply a vertical load at the centre of the beam and a horizontal load of equal magnitude at the top of one column. The static indeterminacy, plastic moment and number/location of the plastic hinges are all determined. External work is commented upon, along with deflection vs. load. Finally conclusions and evaluations are drawn.
