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.
