Steel Structures

3. Awelded I-shape column is shown, which is supported by pins at two ends
and its height is 6m. There is a lateral support in x direction at the center.
Steel is Q235. f,=235N/mm?, f-215N/mm. The flange edge is flame-cut, and
no punching or holes in the section. The classifications about axis x and axis y
can be decided as the Class
section. Determine the design value of axial
load capacity.

II. Calculation Questions
1. The fillet welds are used in the joint. The design
value of the weld strength is f" = 160N / mm² .The leg size
of the welds is h=12mm (tabs are used). The design
values of the static loads are N=550kN and
P=500kN, respectively. Check whether the welded
connection satisfactory?
(unit in Fig: mm)
