CE3050: Basic Structural Steel DesignJuly – Nov 2012

Faculties: B N Rao and Arul JayachandranTutorial No. 3

1. A single equal angle 100 x 100 x 8 mm is connected to a gusset plate at the ends with 20mm diameter bolts of 8.8 grade to transfer tension and the connection length is 150 mm. Determine the tensile strength of the angle and skectch the connections

Yield stress of steel (fy) = 250 MPaUltimate stress of steel (fu) = 410 MPaBolt gauge distance (w1) = 60 mm2. Repeat problem 1 to find the tensile capacity of the angle connection shown below. Assume all relevant data.

Comment on the tensile capacities between Problem 1 and Problem 2. How can you improve the efficiency of the connection?
