5.14-2 Design a bearing plate of A36 steel to support a beam reaction consisting of 28 kips dead load and 56 kips live load. Assume that the bearing plate will rest on concrete with a surface area larger than the bearing area by an amount equal to 1 inch of concrete on all sides of the plate. The beam is a W30 X 99 with F, = 50 ksi, and the concrete streng th is f. = 3 ksi. a. Use LRFD. b. Use ASD.

Determine (approximately) the force in each member of the truss. Assume the diagonals cannot support a compressive force.

Problem 7 [RC Column Design] The short spiral column shown uses eight no. 8 bars. Assume the total loading has a low eccentricity. f.' = 3500 lbf/in², and f, = 40,000 lbf/in?. Determine the design strength. 8-No. 8 bars 22 in

From A to B it is 7.5ft, from A to G it is 24ft.
