I agree with Jayrod12 regarding his recommendation for relocating the vertical reinforcement. If I could offer another suggestion...I would avoid welding the #6 verts to the steel cap plate. I see you have the correct grade, etc. called out, but if you do some research on weldability of rebar...
TehMP.... once you pass the SE exam, you will not have any problems becoming a PE in other states. I passed the SE I and SE II back in the day when the test was two separate parts and the SE II was optional to be a PE practicing structural in most states. Only a hand full of states required...
It ALL comes down to the individual state or states you are licensed. Many states do not license by disciplines, so in those states we are all PEs who are authorized to practice engineering. Bound by a code of engineering ethics, we (PEs) agree that we will only practice in the areas where we...
Perhaps pressure washing or steam cleaning would resolve the issue without scratching the glass. Otherwise if the glass is already or does become damaged after attempts to clean it, could it not be claimed on the insurance loss along with the other damages caused by the pipe burst?
In the Southeast...

I have attached a sketch of the existing conditions. Understood, I realize I'm going to loose the bracing point in one direction (no bracing exist in the other direction out of the page). The connections are bolted (4 bolts each flange of web per column). In it's existing state per the...
I've thought about the KL/R factor...I'm not sure that would be an issue, as I'm not changing the L value of either column section, but rather trying to create a stiffened point that would act as a braced location where the continuous beam exists now. In my mind, essentially the columns will...
I am working on demo plans for an existing structure. There is an interior mezzanine that the building owner would like to remove. The demo is simple for the most part, but I do have a few areas of concern. There are several locations where a continuous steel beam spans across columns running...
How overstressed are the current rafters? IBC Chapter 34, Section 3403.2 allows up to a 5% overstress when adding to existing structures. Also if using ASD to analyze, try using LRFD, you'll probably see a little more capacity.
Have you tried contacting anyone with AISC? I would think they could point you in the right direction.
Shooting from the hip...I would think that A36 steel performs poorly to other grades due to the high amount of carbon content, which causes this grade of steel to be one of the most brittle of...
a2 - Gotcha! Makes sense after reading jt's recent post explaining the layout.
jt- I agree with a2. Some load-distribution may be present but due to the lack of rigidity of the plywood, I would think it would be very minimal, not to mention quite time consuming to calculate even if you have...
Sounds like you're on the right track.
Again, I would suggest talking with a glass/window supplier to understand the limits of the different systems available. From my experience, these appear to be very large panels of glass AND in a high-wind zone. With having a 14' clear span of glass, I...
Stellion makes an excellent call. I would make sure the owner is made aware of the repercussions of not using impact resistant glass. I might also suggest something in writing as well. Atleast for your protection your professional opinion will be in writing, on the record should anything...
For designing wood members, the repetitive member factor is only applied to the bending stress (Fb), as Mike mentioned, and not to the modulus of Elasticity (E). Check Table 4.3.1 of the NDSWC for applicable adjustment factors. When calculating deflections for solid wood sawn members, see...
To all: Thanks so much for your quick responses and sharing information.
One last question...assuming the electrical/computer designer supplies me with all necessary loadings superimposed on the structure, are the cable tray designs themselves typically done by the Structural EOR or is this...
