Steel Beams in garage, wrap with gyp?

[mark handler]

doen't CA have a residental code or is the CBC for everything?

As of 2011, the State has the CA Residential Code which is a "Modified" 2009 IRC

That's why I said the issue of "one hour" is Moot.

"moot"......of little or no practical value or meaning; purely academic.

It is moot for this discussion, but what is not "moot" (for many who may be reading this), is that a "fire rating" is not given to ONE material a "fire rating" is only given to an "assembly" (i.e. a floor/ceiling assembly with all the components, a wall assembly with all the components). The term "thermal barrier" when used with for instance gyp "1/2" gyp has a 15 minute thermal barrier) is NOT a "fire rating". And one must be clear as to what constitutes a fire rating or some other requirement such as a thermal barrier.

What the previous UBC code called for aq one hour occupancy separation.

Are you happy?,

does it change anything?

No, It is MOOT.

If you want to see people really look at you like you are an idiot......tell them they have to wrap the lally columns in that garage also......

I haven't seen a lally column in a garage in forever, all are clearspan here, one way or the other.So, do you have them wrap steel supporting structure such as beams and lally columns?

Interesting the language previously posted, if read carefully, does make my point

2001 CBC

302.4 Fire Ratings for Occupancy Separations. Occupancy

separations shall be provided between the various groups and di

visions of occupancies as set forth in Table 3-B. For required sep

aration of specific uses in Group I, Division 1 hospitals and

nursing homes, see Table 3-C. See also Section 504.6.1.

Exceptions:

3. In the one-hour occupancy separation between Group R, Divi-

sions [for SFM] 2.1, 2.2, 2.2.1 and 3 and Group U Occupancies, the

separation may be limited to the installation of materials approved for

one -hour fire-resistive construction on the garage side and a self-clos

ing, tightfitting solid-wood door 1⅜ inches (35 mm) in thickness, or

a self-closing, tight fining door having a fire-protection rating of not

less than 20 minutes when rested in accordance with Part II of UBC

Standard 7-2, which is a part of this code, is permitted in lieu of a one-

hour fire assembly. Fire dampers need not be installed in air ducts

passing th rough the wall, floor or ceiling separating a Group R, Divi

sions [sFM] 2.1, 2.2, 2.2.1 and 3 Occupancy from a Group U Occu-

pancy, provided such ducts within the Group U Occupancy are

constructed of steel having a thickness not less than 0.019 inch (0.48

mm) (No. 26 galvanized sheet gage) and have no openings into the

Group U Occupancy.



"in lieu of a fire-rated assembly" you may build "one-hour fire-resistive construction on garage side"

Now, I am happy.

All that verbiage and the thinking that goes with it gets you where? You point at a steel beam and proclaim that it shall be protected. You are asked what you expect for protection. Two layers of 5/8" type X little lady and Shirley we're off to races.

I have to......

I Actually had this happen recently, if you look at this picture you'll see where the engineer had one Valley hanging under another valley at the back of the forklift, that's in the garage wall, the W8x24 is capped with a ¼" plate but sticks by the little post over it by about 2". when the rockers covered the wall with 5/8" sheetrock they left that 2" sticking through, I told them to "Double up the 5/8 to cover it", they took that to mean "double the sheetrock" ignoring the cover part. When the inspector arrived for

the sheetrock nailing inspection I apologized, told him what happened and asked him to sign me off and he could check it on the next inspection, he told me that there was no need to cover it, just let it stick out. When the rockers came back to do other things I had them put three more layers on it to get one layer to cover it up for aesthetic reasons, the garage is getting 5/8" all over and then plastered with diamond coat.View attachment 684

Like they used to say in engineering school, RTFQ before trying to answer it ICE.
