In ACI 318 Table 25.4.2.3, does the upper part of the table "Spacing and cover", refer to non-contact lap splices and the lower part " other cases" refer to contact lap splices? Is that the intent of the table?

Below is an excerpt from the Code Opinion that I received from ICC. Section 102.6, as referenced in your e-mail, deals with the legal occupancy of a structure. Buildings that exist legally at the time the code is adopted are allowed to have their existing use and occupancy continued if the...

But if the equipment had been installed in 1995, we would not be having this discussion. And it would be fine. I have submitted a formal request for interpretation to ICC. I will post the response when I receive it. Thanks again for your participation.

Thank you all for your responses. I agree with all of the comments regarding additions. In this case, the building was designed for 2 reactors. Only one was installed. Now we want to install the second one. So, it is not an addition. We are not increasing the seismic demand beyond that as...

I have a building that was designed 30+ years ago for two reactors. Only one was installed. The owner wants to install the second reactor. Does the building need to be seismically evaluated for the current building code? IBC Section 102.6.1 A building or portion of a building that has not been...

I do not know how to respond to individual responses directly in the posts, so I will do it here. EngDM, I read in an earlier post that ACI does NOT allow for the area reduction with regard to shear friction. I still need to verify that and read the appropriate code section. SlideRuleEra, I...

I think i am asking a more fundamental question. It seems to me that the anchor break out analogy is valid. It is extremely conservative because all of the load goes through the anchor. In shear friction, a large portion of the shear goes through the concrete. If you roughen the concrete and use...

I have an 8" thick slab with a 5'-0" span over a utility chase. The contractor was replacing some concrete and they saw-cut completely through the slab about 4" short of the side wall. Slab is drive way for truck traffic. The proposed repair is to dowel in some #6 bars @6" OC and re-pour the...

RattlinBog, Thank you for your response.

Does MSHA have platform and stair design requirements similar to OSHA? If they do, where can I find the design specs? Or do they reference IBC?

How are Engineers in the southern US handling snow drift in a 5 psf ground snow load region? The commentary states that a 3 or 4 foot drift could occur in regions of low ground snow load. My roof length is causing a 6 foot snow drift. That seems completely reasonsable here in the Midwest. But I...
