    Baseplate to nut contact

    Picture is attached, although you can't tell that the foundation has tilted.https://files.engineering.com/getfile.aspx?folder=eea8bfd4-b4f9-4c22-825e-44284ad2ff59&file=20240801_125929.jpg

    Baseplate to nut contact

    Hello, I have a situation where a steel column (exterior, W12) is leaning due to the foundation heaving about 3/4". The foundation is at least 30 years old, so is the steel. I guess the issue was recently notice by the facilities. In order to correct the issue "temporarily", the site crew...

    12" CMU fire rating

    BA, I think you are correct. That appears to be a reference to horz reinforcement.

    12" CMU fire rating

    Thank you all. @BA, just checked the drawings again. Built in 1972, in Chicago. The drawings show "Wall reinforcing every second block course". Which likely means grout @ 16" oc.

    12" CMU fire rating

    I am looking at a 12" cmu wall from 1970s. The drawings appear to show the wall grouted @ 48" oc. I am trying for find some fire rating dates for CMU from that era but not finding anything. What be a good resource for this information? Thank you.

    F1554-Gr 55 Gavlanized-Welded Studs

    Is there a load chart available for using these F1554 anchors as welded studs to a plate? Thank you.

    CMU-Cantilever height

    I am looking at aprox 13' tall exterior CMU wall. Non-load bearing. Of course it will have to resists lateral loads (likely wind, since its Michigan). Before I start designing in detail, are there any cmu max height requirements for a cantilever wall? Thanks,

    15' tall, 8" cmu wall, cure time?

    Single story masonry building with precast roof. Wall height aprox 15', 8" cmu. My question is about putting the roof (precast planks) on the wall once the wall is complete. How long should the contractor wait before placing the loading the wall with planks. Thanks.

    Digging around 12' pier

    Consider a 3'x12' deep pier foundation supporting an out door structural column. The contact tor was supposed to pour a pipe within the concrete. The contractor forgot to do that. They are recommending digging down to one side of the pile 9' deep to install the pipe and fill the void with grout...

    Exp joint-190'x232'

    JAE. Thanks. My structure is concrete so I think I should be able to go 232' w/o a joint.

    Exp joint-190'x232'

    190'x232' sports arena (single story). Roof is metal deck on steel trusses. The structure itself is concrete a frame (columns wand beams). The temp range is 90 F. But the project is an area where air-conditioning (heat and cooling) may not be functional. I can't decide if an building expansion...

    Seismic design of concrete water tanks

    I understand that I have to use ACI 350 for concrete. But for seismic forces, what standards should I be using?

    CBC & IBC-Differences (seismic)

    Are there any major difference between the latest 2013 California BC and ASCE 7-10 for seismic design? I recall that in the previous codes some of the R values were different between the two but I can't seem to find any differences. I don't reside in CA and use CBC only occasionally.

    CA-Engineering Surveying and Seismic Principles exams

    Hokie. Thanks. Just ordered both of these. Both look useful references.

    CA-Engineering Surveying and Seismic Principles exams

    Thanks Lomarandil. I just want to gauge the type of questions to expect, especially for the survey part because I don't survey for a living.

    CA-Engineering Surveying and Seismic Principles exams

    I am preparing for these exams but I can't find any example test to figure out the format of the exam. Does anyone know if there are example test references available? Thanks,

    Concrete costs

    I am working on preliminary cost opinion. Where can I find CY costs for concrete (foundations, conc on metal deck etc). Location=Chicago.

    3/4" A325 N bolt-nut penetration

    Should any structural bolt have a complete penetration of the nut or is there some leeway to allow not to? I am looking at some structural connections where the bolt doesn't penetrate the nut entirely. Can a partial capacity be assumed from partial penetration?

    PE registration in CA

    I am planning to register as PE in CA. I am currently registered with NCEES so I think that should make things easy. But I am not sure about "California Civil exams in Seismic Principles and on Engineering Surveying". It appears that I can take this computer based test from my home state (IL)...

    7.8 Quake in Nepal Saturday

    I wonder if they have a working building code there. Pakistan had a huge earthquake a few years ago (80,000 + casualties) and USAID helped them in coming up with a building code. But basically they modified UBC 97 from what I understand.
