Determine for the following gravity loaded bending member sc

Determine for the following gravity loaded bending member scenarios if the lateral stability factor, C, must be included as an adjustment in analysis of the member. a. b. C. d. e. 2 x 8 joists with end blocking 2x10 with sheathing nailed to top 20 ft long 2 x 12s with blocking at midspan and ends 6x 10 beam with 2 x joists at 2 ft o.c. stacked 6x 10 beam with 2 x joists at 16 in. o.c. in plane Must Include Yes No Yes No Yes No Yes No Yes No

Solution

CONDITIONS where C_L calculation can be avoided assuming C_L =1

1)depth of the member less then it\'s width (d b)

2) When rectangular sawn lumber is braced in accordance with Section 4.4.1 of the NDS.

3) if compression edge is supported throughout it\'s length to prevent lateral displacement, and the ends have sufficient connections to prevent rotation.

otherwise, C_L must be calculated fr the rest.

so for a ) B) and e) it should be calculated
