A photograph of the earthquake damage to a house. Large cracks have formed in between the bricks in the wall of the house. There is also a large crack on the left side of the second storey where the column has shifted.
Perimeter Moment resisting steel frames (PMRSFs) are a commonly used seismic resisting system, placed around the perimeter of the building for maximum torsional stiffness. They are typically designed as “strong column weak beam” systems with fixed column bases. When subjected to severe earthquake demand, sufficient to push the beams into the inelastic range, it is expected that plastic hinging at the column bases will occur. However, the response of PMRSF systems to the severe 2010/2011 Christchurch earthquake series did not generate column base hinging in systems which exhibited beam yielding.

A photograph captioned by BeckerFraserPhotos, "The failed column near the south-east corner of the ground floor of the Hotel Grand Chancellor. This corner of the building slumped 700mm when this column and a nearby sheer wall failed. Scaffolding was erected all around it and then sprayed with concrete to stabilise the building".
