Load evaluation; materials and design criteria
Pre Lab Exercise
Examine the second floor balcony of Pavilion II on the Lawn; the balcony is
supported in part by tension rods.
Provide answers to the following questions, submit your answers on a single
8.5x11 sheet, written on both sides. Hand in the answer at the beginning of
the Lab meeting.
- Do all the rods carry the same load?
- If not, which rods carry the most load?
- Based on what you can see, sketch a reasonable framing plan showing the
organization of the balcony framing. Indicate the location and orientation
of joists and beams, the supporting rods and walls, and approximate dimensions.
- Based on your framing plan, determine the tributary area of the rods carrying
the most load.
- Review the uniformly distributed live loads listed in table 3-3 of Schodek
and determine which load would be most appropriate for the balcony (this
is a judgment call, since the table does not address this situation directly).
- Assuming the balcony has a dead load of 20 psf (something we could calculate
in more detail based on assumptions about how the deck is put together),
and using the live load you selected above, calculate the maximum load on
a tension rod.
Do the following problems from the notes during the lab session:
