Use the LRFD METHOD AND PLEASE SHOW ALL THE STEPS AND HOW YOU GET THOSE NUMBERS.

Thank you so much

The following figure is showing the top floor of a five$-$storey residential building to be designed in Long Island region. The service dead load $($including self$-$weight of slab$)$ is $50$ psf$,$ service live load is $60psf,$ the snow load is $15psf.$ The length of $AB=BC=CD=20ft$ and $AE=EI=IM=10ft.$

Design the most economic and lightweight sections for the beam and column as mentioned below and submit a report with comments on the design

$3.$ Beam JK and Column K $($

Assume, the length of each column is $18$ feet, fixed at both ends.

The deflection limit of each beam is $\frac{L}{360}$ where $L$ is the Span.

Use the LRFD

for the beam design there are $3$ spans and they are not simply supported beams

for the column its is a fixed supported at both ends

Use page $421$ Figure $39$ in the Aisc steel manual

Also do at least $3$ trials

With the numbers plugged in
