Supplemental Homework

Week #$2$

$2\mathrm{.}1$

Given:

The framing diagram shown below.

Assume a $100$ psf gravity load $($includes both dead and live load$)$

Assume that the self$-$weight of the framing members is not significant $($i$.$e$.$ you can neglect self$-$weight$)$

Assume there is decking $($not shown for clarity$)$ spanning between the beams.

Calcurations:

Load Tracing

Using the load tracing method, develop complete free body diagrams for members B$1,$ B$2,$ G$1,$ G$2,$ C$1$ and C$2.$ Be sure to include both the applied forces and the reaction forces on the free body diagrams.

$2.$ Tributary Area

Using the tributary area method, develop complete free body diagrams for the same members as part $1.$ Be sure to include the applied forces and the reaction forces on the free body diagrams. As part of your solution, sketch a small framing plan for each member showing the tributary area.

$3.$ Comparison

Create a simple table comparing the reaction forces for each of the members for both the Load Tracing and Tributary Area methods. If there is a difference in the results, explain why.
