Group Assignment:

The objective of this assignment is to work collaboratively with your peers as you would in a professional setting. You will locate specific structural elements in each of the parking structures on campus. Using your knowledge of structures, you will estimate the forces on these members and develop Shear and Moment diagrams for them. You will need to estimate the tributary width as well as the applied loading. You will need to sketch the structural elements from various angles, plan view, elevation, cross section, etc. to show you understand the load paths in the structure.

Roof level loads contain snow and there are two types of snow load on flat roofs.

Roof snow load as if the roof were flat.

Roof snow load with the consideration of drifting.

Instructions:

Create a team of $2$ or $3$ students.

Locate the structures on campus.

Walk both the Precast Structure and the Cast in Place Structure. Identify a flexural member at the roof level in both structures to investigate.

Measure the sections and make sketches as you will need to estimate their dead load and span. Include:

Self$-$weight of the Structural Beams

Floor Member Dead Load

Topping $-$ Assume $3"$ normal weight concrete over the DT in the PC structure and assume $8^{\text{'}\text{'}}$ CIP slab in the CIP structure.

Curbs $-$ Use actual size over and above topping

Assume normal weight concrete.

Measure the bay sizes to establish the area subjected to dead loads, live loads, mechanical, and snow.

Look for mechanical loading. Make an assumption of $5$psf$,10$psf$,$ or $15$ psf

Determine design Live loads from ASCE $7$ Table $4-1$

Draw a free body diagram of the loaded beam and determine the end reactions for the following conditions:

Service Level Loading $($Dead $+$ Live$)($Exclude snow$)$

Ultimate Strength Level loading considering Snow.

Draw Shear and Moment Diagrams for the same loading conditions.
