A beam is built-up from the following plates: 450 x 20 mm as
flanges and 500 mm x 20 mm as web. All plates are A36 steel with Fy = 248 MPa and the flanges are continuously connected to the web by means of fillet welds. The beam is simply supported at its ends and laterally supported only at supports.
