631 Given The rafter connection in Fig 6F The load is a comb

6.31 Given: The rafter connection in Fig. 6.F. The load is a combinationf and F\'s = 560 lb. Consider the D + SASD) or 1.2D + 1.6S bination. Lumber is No. I spruce-Pine-Fir (South). C-1.0 and C Find: a. The actual bearing stress f.i in the rafter and in the top plate of the wall ASD) b. The adjusted ASD bearing value Fei in the top plate. c. The adjusted ASD bearing value Fee in the rafter Beam Design 363 /2 6 2XIO RAFTER 2x4 STUD WALL Figure 6.F d. Factored bearing load P, in the rafter and in the top plate of the wall (LRFD) e. The adjusted LRFD bearing resistance Ph in the top plate. f The adjusted LRFD bearing resistance Pne in the rafter.

Solution

The flange plate thickness appears to be 20mm thick and 150mm wide and the web appears to be 16mm thick and 600mm depth.

The end connection can be assumed to be moment resisting frame connection.

To be supported on a concrete pad with no less than 8\'\' thick reinforced top and bottom with T8 bar @ 4\'\' c/c.
