Given: A W14X109 column (A992 steel) requires a base plate (A36 steel) design. Assume the base plate will be on the full area of concrete support. The dead load compression in the column is 320 kips and the live load compression in the column is 600 kips. The concrete support under the base plate has a 28-day strength of fc 5 ksi. Required: Design the base plate with the goal of minimizing the required thickness.

15.3. psi. Design a single-column footing (including dowels) to support an 11 in. square column reinforced with eight No. 9 (No. 29) bars centered 2.5 in. from the column faces (equal number of bars on each face). The unfactored axial dead load = 135 kips, and the unfactored axial live load=125 kips. For the column, f=4000 psi and f=60,000 psi. The base of the footing will be 3 ft below grade. The allowable soil bearing pressure is 3000 lb/ft2. Material...

Complefe the following: problem Parameters/notes Change the load: Dead -10 psf. Live - 30 psf hint: first trace the load W to the ends of the rods, then draw a FBD of the beam and rod and solve for reactions at C and B. Use this info to find the force in the rod. Your answer should be the diameter of a round rod rounded to 1/8" increment). Change the load to 400,000 Ibs See Appendix table A3 for Steel...

A design calls for a centrally loaded column consisting of a 12 ft section of square structural tubing. The outside dimension of the tubing is 4 in. and has a 3/8 in. wall thickness. If the design calls for a load of 30 kips, is the column in danger of buckling. What happens if the column is solid and not tubing?

Design a slip-critical bolted connection for the following conditions: • All structural steel is A36 • Length = 10 ft. • The tension member is 2L7 x 4 x 7/16 LLBB. • The connection will be to a 3/8-inch-thick gusset plate • Service dead load = 50 kips and service live load = 100 kips. Provide a complete sketch showing all information needed for the fabrication of the connection. Use LRFD.
