Situation 1 | A built-up beam made from fastening two channels to a wide flange section carries loads as shown. The fasteners are 12mm bolts with allowable shear stress t= 110 MPa. For bearing, ob= 220MPa for single shear, and b= 275 MPa for double shear. E=200 GPA. Fy=420 MPa. 238 mm A 90mm 16 KN/m 9mm 4m 210mm 180mm 180mm 210mm 12mm B 1.35m 3.15m D 10 KN/m 1.5m E

a) The short steel post as shown in Figure 4 is a 152 x 152 UC37 with three compressive loads applied to the top. There is a central load of 200KN and eccentric loads of 'W kN and 100kN. The maximum allowable stress on the face AB is 185 N/mm?. (Area=D47.1cm2,Zxx=273cm) What is the value of the load 'W in kN? WkN A. 152 x 152 UC37 100mm -200KN 50mm 100KN Not to scale Figure 4

A stud wall panel has an overall height of 4m including top and bottom rails and vertical studs at 400 centres with nogging at mid- height. Assuming that the studs, rail framing and nogging pieces comprise 47 x 125mm section of C24 strength class, calculate the maximum uniformly distributed medium term load the panel is able to support.
