A 3-bay truss is simply supported on two masonry walls. The truss is subjected to dead loads, roof live loads, and snow loads. The maximum tensile force Pu in member CE from all LRFD load combinations is equal Pu =74 k. Member CE is a singleangle L6x4x3/8 connected to the gusset plate using one bolt 7/8 in in diameter. The angels are A36 steel (Fy = 36 ksi and Fu = 48 ksi). The edge distance from the center of the bolt to the end of the angle is 4 in as shown. .Determine Pn, the design tensile strength of member CE (the minimum of the design yield strength,design rupture strength, and design block shear strength). Is member CE adequate?
