Prepare and submit three conceptual truss elevations based on the project constraints listed below to

connect the WAEC building to the adjacent Robert C$.$ Byrd Biotechnology Science Center. These

conceptual elevations can be hand$-$drawn $($neatly$)$ or generated using any CAD software of your choosing.

For each layout, confirm that $i_t=0$ and that the truss meets both member length requirements as well as

envelope requirements.

In addition, choose one layout for final design and describe your selection strategy for choosing said

layout. This description should be no more than a paragraph long, and your selection strategy can be

based on any parameters that you deem important $($i$.$e$.,$ number of members, independent research, etc.$).$

Note that individual member selection, stress$/$deflection computations, and cost estimates are not required

for Submittal $1.$ Those will be completed during Submittal $2.$

Submit as a single PDF via Blackboard.

The truss shall be laid out according to the following parameters:

Truss Design Parameters:

$L=120$ feet

Walkway Width $=24$ feet

Load $=950$ psf

Limited to W$12$s

${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=32$ksi

${}_{\text{m}\text{a}\text{x}}=\frac{L}{400}$

Steel Price $=$$$\frac{2\mathrm{.}18}{l}b$

$E=29000$ksi for all members

Project Constraints:

$i_t=0($for all layouts$)$

Truss is simply supported at the ends.

Truss must contain a joint at midspan

along the bottom of the truss.

No individual truss member may exceed

$22$ feet in length.

Truss members must be straight $($i$.$e$.,$ no

arches or curved members$).$

The truss must not exceed an envelope

$+-16$ feet from the walkway $(=16$ feet$).$
