I am trying to design the connections of the 4x6 knee braces inside of a 5.5x5.5 column and 5.5 wide beam. I would like to use screws that do not require pre-drill. However, with the brace in compression, how do I account for the lateral resistance of the dowels that actually go through the...
Attached is my hand calcs for a wood deck joist which matches the calcs in the program Enercalc. However, both state the beam does not pass bending code check by almost 50% when the IRC TABLE R507.6 says it should be acceptable. Is this another issue similar to deck ledger bolt spacing such...

Wanted to get suggestions on what to include in a custom report from Risa to provide plan reviewer that makes the most sense while keeping the reports to a minimum of pages. Small...
Anyone know the best way to model 1/2" plywood on new single level gable roof addition to house such that it can be shown to provide adequate lateral load resistance. I have created plates between each roof rafter and meshed them (this I believe I have done correctly to transfer load from plate...
If a lag screw penetrates fully through the side member, is there still and 4D min penetration requirement for lateral load or is using the side member thickness for bearing okay (i.e. using 3/4" dia lag through 1-1/2" wood side member where 4D min would be 3" but the side member is only 1.5")...
This one is a real RISA 3D mystery. I have been trying to use Risa for wood design for nearly a year. The problem I am having which the Risa engineers have not been able to resolve is described below. Is anyone else using Risa for wood and having the same issue?
I select material to use and...
Does anyone know if the the NDS connection Mode Reduction terms Rd are to be used in place of the Hankinson Formulae. Do the two address different issues?
