Problem 2 to Problem 8are all based on fellowxing preblem statemel In Fig. 2, the double angle 2L4 x 3 ? x1/2 of A36 is subject to tensile load, among which dead load T120 kips and live load Ti-50 kips. The diameter of bolt hole is 1 in in standard hole. The strength of A36 steel is Fy-36 ksi and Fu-58 ksi 1 34* 1.51 25 2.5 Age3.5 in One angle) Fig.2

Solution

For caluclating net area total area of the out standing leg and effective area of the Connectd leg is to be take.To calculate the effective area we have to deduct the diameter of the bolt hole i.e,1 in
