The connection in Fig. 13.B uses side plates of A36 steel and four 1-in. diameter bolts on each side of the splice. Bolt spacing is 4D and end distance is 7D. Lumber is No. 1 DF-L. The force is seismic.

Find: Adjusted LRFD design value for the bolts if:

a.
 = 1.0.

b. Green lumber is used that later seasons in service.

c. Connection is exposed to the weather.

d. Lumber is above the FSP in service.
