A channel is used as a tension member with the web of the channel welded to a 9.5 mm thick gusset plate as shown in the figure. The tension member is subjected to the following axial loads. Use LRFD
Service dead load = 200 kN
Wind load = 276 kN
Service live load = 260 kN
For channel:
Fy = 345 MPa
For gusset plate:
Fy = 248 MPa Fu = 400 MPa
Size of E 70 electrodes = 4 mm
Ultimate tensile strength of E 70 electrodes = 480;
Fw = 0.6(480)
Questions :
a) Determine the design factored tensile force.
b) Determine the length of longitudinal welds "L".
c) Determine the block shear strength of the gusset plate.
