Assignment

For this exercise consider the single$-$bay building framing plan shown below. The thickness of the oneway slab spanning between the beams has been determined to be five inches.

Interior beam design: Assume all beams are simple span and design the typical interior floor beams for moment. Design the beams as rectangular sections.

Edge girder: Assume the edge girders are simple span and design the girders for moment. Design the girders as rectangular sections.

Use a design $($unfactored$)$ live load of $80$ pounds per square foot. Include the weight of the slab, beams, and girders in the dead load plus include an additional $10$ pounds per square foot of superimposed dead load $($weight of ceiling, lights, mechanical ducts, and floor finish$).$ Assume the width of the interior beams is twelve inches. The columns are ${15}^{\text{'}\text{'}}{15}^{\text{'}\text{'}}$ and the width of the beams and girders framing to the columns will be the same width as the columns $($that is$,$ fifteen inches$).$

Use $f^{\text{'}}c=4$ksi and $f_y=60$ksi.

Include a sketch describing the final beam and girder sections. On your sketch, be sure to indicate $-$ but do not design $-$ the shear reinforcement $($that is$,$ the stirrups$).$
