A2.2. Plane Steel Frame
Problem Description
A one-story plane frame subjected to vertical or horizontal loading is examined (Figure
A2.2.1).
Geometry, Properties and Loads
The span opening is 7.0m and height of vertical members (columns) is 5.0m. The cross
sections of columns and horizontal members are IPE-450 and IPE-330, respectively.
Modulus of elasticity of the material is 210GPa and Poisson ratio is 0.30. Footing’s
dimensions are 150cmx150cmx50cm for each column and ground stiffness is 100kPa/cm.
Two cases of loading are studied. According to the first one, self-weight is taken into
account (ε

) and horizontal member is subjected to distributed vertical load of
10kN/m (Load Case 1). In the second case, self weight is ignored and column AB is
subjected to a distributed horizontal load of 5kN/m (Load Case 2).
