No displacement of the nodes that were fixed in all degree of freedom was allowed. However, the beam fixtures of the real test consisted of two bolted connections that had allowed the beam to twist. Also, the loading steel pin linking the post to the crosshead permitted swivelling of the post and deformation due to the pin
