Use LRFD and select an American Standard Channel shapefor the following tensile loads. Dead load=54 kips live load= 80 kips and wind load=75 kips. The connection will be with two 9inch long longitudinal welds. Use an estimated shear lag factor of U=0.85. Once the member has been selected, compute the value of U with equation 3.1 and revise the design if necessary. The lengths is 17.5 ft. Use Fy= 50 ksi and Fu=65 ksi.
