$2\mathrm{.}1$

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.

Calculations:

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.

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.

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.
