When you say "take into account", do you mean dividing the roof dead load by the cosine of the roof slope? If so, that's a 3% increase for 3:12 roofs, 12% for a 6:12 roof. If so, my answer is "yes" (in either case). My biggest concern is that, without rafter ties, collar ties or ceiling joists...
Not if they are designed properly, and, to resist 200 lbs at a height > 3.5 feet, as you know, can become quite onerous. If it were an impact load instead of a live load, I would be ok with that.
According to the NDS spec, you don't have to worry about it if l/d<4 which is a 2x6. If it's deeper than that, you have to consider distance between lateral supports. The reason "99.9%" of the beach houses have not failed is that they have not been subjected to the design loads. Lack of failures...
I work with a lot of contractors who would take offense to this comment and attribute it to "just another arrogant engineer", who hates to go to the jobsite, doesn't know what he/she is looking at when they get there and provides woefully inadequate details to describe how they want it done...
Executive Summary: Happiness is more important than money.
I've worked for others for 10 years and now have been on my own for 37 years. While I worked for others, I tried to get into more conventional structural engineering firms, designing buildings, etc., but for an engineer with little...
I don't see any such restrictions after a quick perusal of Simpson's catalog C-F-2023TECHSUPP.pdf. You can also get them galvanized (TBG). If your steel flange is greater than 1/4" thick (but less than 1/2" thick), you would have to go with the TF screw, which is not available galvanized. Seems...
I found this in the Enercalc Help Manual:

This seems like what I was looking for in my "mind's eye".
1. Put in address.
2. Click "search".
3. Select version of ASCE-7. -22 is the current version (and will be for California in 3 weeks).
4. Select Risk Category. Category II is the most common.
5. Select Site Soil Class. In 7-16, select D (default). In 7-22, select "Default" unless you have...
I've wanted to reply to threads like this for a long time and, until now, I've successfully resisted. Today, my resistance is low. The following is my two cents and not intended to offer any career advice to anyone. I took the SE exam in California in August, 1983 and got the results 7 months...
Check out Simpson TBP Strong Drive Screws or TF Screws
Download C-F-2023TECHSUP.pdf from Simpson's website.
p. 212 for TBP screws.
p. 213 for TF screws.
It depends on the actual stresses. For example, if a GLB is graded as 24F-V4. The allowable tension stress on the bottom face is 2,400 psi and the allowable tension stress on the top face is 1,850 psi. So, if the net tension stress in an uplift condition does not exceed 1,850 psi (plus...
Three options come to mind:
1. File a lien. I've never done this because there are procedures which can make the lien voidable. Too much legal stuff to go through to make this worthwhile.
2. Small claims court. Fairly easy to do except for the time it takes you to go to court. Results can be...
Qualitatively, I agree with KootK. Quantitively, if you want to put numbers behind it, you can easily do so (in my feeble mind, anyway). You do not state the length of the shear wall or the total shear load. If the total shear wall length is 10 feet and the shear load is 2, 000 lbs, then the...
