After reading all of these posts at one time, dhengr's stands out to me as requiring the least material, least labor, and least modification to the existing structure. One add on to this is could you somehow use the existing columns (cut off near the top) in the attachment to the cross beams...

If you review Section 4.4.1.6 Item 2 you will find how the SDPWS acounts for this rotation. I would use this as a starting point for accounting for rotation of the sill plate. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

If you use hurricane ties to transfer the uplift into the bottom plate you still have to transfer that load into the foundation. You would be required to design the sill plate for this load. Instead of leaving this up to the Engineer, the SDPWS just prescribes anchor bolts at 16" o.c. Jason...

As Mike stated, I would first run the analysis with the reduced section to determine if the beam needs reinforced. Make sure you account for any overcut when determining the depth of the member. If it needs to be reinforced, check with the supplier or manufacturer as stated by 4thorns. I...

The ICC manual includes design information for wood and other materials and references the WFCM for anything other than wind loads. I would download the WFCM guide for the specific wind speed that you need. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

The American Wood Council and Southern Pine council have free downloadable guides to get you familiar with the design and details. Also, a discontinued textbook by Hoyle and Woeste has a chapter on this type of design. The Wood Handbook may have something. It is available as a free download...

spats and IceNine, The repetitive member factor is used to adjust the allowable design stress for the member you are designing. The allowable design stresses for wood are based on the 95th percentile of actual load capacity. So for every 100 joists loaded, 95 will have an actual strength...

You mentioned spacing in your post. Is this nail spacing? For a continuous fascia, I would expect limited height for nailing and specify the # of nails per rafter/truss. The method for calculation mentioned is good. I would also consider a man load centered between the supports. Jason...

Like Mike stated, the connection is critical. I agree with adding sheathing on the interior face of the wall. I would add full depth blocking between the studs at some elevation and attach the new sheathing to it. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

There is an ASTM for repetitive member wood assemblies (ASTM D6555). I have not read it, but I think it is more expansive than the NDS description. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

I would recommend that you contact someone with WoodWorks at www.WoodWorks.org They offer free consulting for stuff like this. They also have design examples fir wood frame construction on steel lower levels. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

As an aside, I would not use T&G plywood for anything but a floor. APA recommends using a 1/8" gap between panel edges for a roof, which is usually achieved through the use of ply-clips. This allows for expansion of the wood panel. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

There is and ASTM that covers visual grading of existing lumber. I think it is ASTM D245. Jason A. Partain, P.E. www.myconstructionfinds.blogspot.com

Another option is to volunteer for work with your state SEA. This is a good way to get organizational work experience, meet fellow engineers in your state, and get your feet wet working with others. Also, this limits your travel needs, which is great if you have to pay everything out of...

This is a sample of a wood stud design article I am writing. Tests have been performed to verify the bracing of wood studs by various materials. The reference article is very good and presents the practical issues related to this subject, as opposed to a typical journal article focusing on...

I have little experience in this area, but I will offer my penny. I would try to estimate the grade and species of material used and then determine an allowable capacity based on published data. IMO the grade and species is the most important part because it should be field determined. Based...

I am not sure what the parameters are for your question, but you can find the historic issues of NDS on the AWC website. This may be another source for the design stresses for the wood in question. I know they have a non-printable pdf of the 1944 NDS that I have used to compare historic design...

Have you checked for any requirements limiting the overall run/rise of stairs between landings?

I only went to the Saturday session which was mostly on wood design. I think whether it is worth it or not depends on you expectations. I enjoyed it and picked up a few things that I did not know. I also enjoy wood design. The guy that I went with complained that it was not worth his time...

Where are you located? I am in Alabama. It would not be cheap to fly me to PA for a seminar. I did go to the Winter Meeting in New Orleans in January.
