7.1 Abnormal efforts

• Unexpected clashes

  The often ill-considered choice of pre-assembled structural parts generally leads to local deformations of bars that are dangerous in terms of buckling if they are compressed when the structure is loaded.

• Misplaced props or supports

  These include, for example, the supports of triangulated beams between two nodes, which can introduce damaging local moments.

• Uncontrolled storage

  Bulk storage on the building site of frameworks waiting to be lifted is strictly forbidden, as it can lead to permanent deformation of the parts and untimely...
