Transcribed Image Text:1. Two channels are joined together by eight 25 mm diameter bolts in single shear as shown.
The bolts spacing are x1=50 mm and y1=60 mm. The steel has yield strength of 250 MPa
and Fu = 400 MPa.
Channel properties:
Area = 3644 mm?
Web thickness = 12 mm
Allowable stresses of plate:
Tension on gross area = 0.60Fy
Tension on Net area = 0.50Fu
Shear on Net area
= 0.30 Fu
Bearing on Projected area = 1.20Fu
On Bolts:
Allowable shearing stress of bolt = 90 MPa
Bolt hole diameter = 27 mm
Calculate:
1.the force P based on bolt shear
2. the force P based on bearing on plate
3. the force P based on block shear
