Jayrod12, I was envisioning some sort of calibrated hydraulic device and hoping you might have some recommendation along that line. Are you envisioning steel cable with turnbuckle? Do you have a recommendation on how to direct a contractor to achieve a prescribed tensile force with a...

I looked at the icc site mentioned above and it seems to be there, although I didn't download it.

Love it!

Thanks Jeffhed, The CL calc, CV calc and live load determination on cantilevered situations seems to be the areas where software differs.

There are formulae I believe based upon the difference between moisture contents at time of construction and in the final equilibrium state (or perhaps it's just rules of thumb based upon years of experience, but at any rate, easily available from AWPA or similar) which I don't have at my...

Haven't used enercalc, but have had similar issues with other software. As far as I am concerned, I always verify. Of course, one of my teachers insisted we form the habit of doing a mental calculation to verify the output of the then new contraption, what's it called... o yes, the hand...

NDS provides formula to determine reduced value of nails with spacing closer than a minimum spacing for full value. Now from memory (Better double check this in NDS!), I think minimum full value spacing is same as minimum full value penetration. And reduction is linear, and drops off cliff to...

It's my understanding that these new values are the result of a process parallel to the process that underlaid the significant downward adjustment of Douglas Fir allowable stress values in 1991 (which, coincident with a recession and the revenge of the spotted owl closing down old growth...

Thank you. I'll check them out.

hi, Does anyone have a recommended software to analyze a grid line full of glued laminated girders with cantilevers, double cantilevers and drop in beams? It'd be nice if it would calculate the volume effect factors. automatic Roof live load reductions based upon tributary areas would be nice too.

"My question is what is the difference in designing reinforcing for the beams if the beam is at full stress and under no stress?" Interesting question. Supposing a beam in bending, I think of the difference having to do with the amount of strain in the existing beam. If the extreme fiber in...

What about the perpendicular direction?

I'm afraid this creates 0 diaphragms, as a diaphragm spans from horizontal supporting element to horizontal supporting element.

So, ideally you're looking for 7 different Douglas fir lumber samples, each pressure treated with one of the seven treatments listed... did i get that right?t

Nice

Balconies always get special attention from me, and especially the handrails, for precisely the reasons stated above. For awhile there, it seemed like every year or so the news carried a story of a balcony coming down with people craning there necks to see a parade, a sunset, an ambulance...

Rweave, Thank you. That is exactly what I found upon my site visit. And you helped me be fully prepared and look good to my client!

I have been asked to investigate this structure by an HVAC installation contractor presumably for a roof mounted HVAC replacement. The told me is is called a "Fullerton style pre engineered steel playplace", and, obviously, for MacDonalds. My searches have yielded no information or history on...

Watch out for for stress reversals in the flat webs under your new loading conditions.

No calcs based comments for you here, but ran this question buy a steel joist manufacturer engineer I know, many years with Vulcraft. Asked him: "in your experience, what floor spans or floor conditions become more susceptible to vibration problems?" His reply utilized a technical term I had...
