a2mfk- The structures I am used to dealing with have a double wood stud wall that serves as the unit separation, each wall is bearing. Between the structural walls there is 2 layers of 1" gyp... the system provides a 2-hour rating. The walls continue up to the underside of roof sheathing. I...
kipfoot,
The IRC commentary on this section seems to indicate that structural independence refers to the abilty of one building to be removed (fire is mentioned) while the adjacent building remains. There is no mention of design lateral loads for the remaining structure, just that it wont...
Thank you all for your responses. Some of the responses appear to be addressing wind load in the "front-to-back" direction. While I see the opportunity to share load through the roof diaphragm (sheathing can be, and often is, continuous over the party/fire walls per exception 2, 706.6), I would...
Wasn't sure where to post this (here or Codes).
For 4- and 3-story townhouses separated by firewalls, resulting in structurel isolation of each unit:
Does the IBC/IRC require (or do you personally consider) the lateral design of an individual townhouse unit to include wind pressures resulting...
Looks like BIA 31B addresses two issues:
1) Deflection is limited to L/600 or 0.3"
2) Torsional rotation is limited to 1/16" (not sure how that is measured)
Since you are anchoring back to a structure it would seem that the angle will be supported at regular intervals, making the deflection...
Agreed BRDENG. Obviously the states have their own sets of rules and could tell you their rule regarding this issue. However, the question at hand is not so much what the rules are, but how to address the rules that are in place. I do not plan on having 50 different buisness cards to adapt to...
Since posting I have done some additional research and have found a way of dealing with this issue that makes me comfortable, since there is obviously no black and white answer.
Many people say that as long as your buisness address is listed along with your name, then the use of PE is assumed...
RacingAZ,
I beleive that the use of PE, SE is appropriate. This means that the engineer has not simply passed the civil or SE1 exam, but has minimally passed both the SE1 and SE2 exams... a much greater acheivement. The use of SE is a perk of passing both exams and satisfying the licensing...
IRstuff, I agree with your statement, if you or others at your firm are not registered in state X. At that point I would make a statement such as, "My firm is not currently registered in X, but we can obtain a license should the project move forward."
On the other hand, what if I am...
I definitely agree on the misuse of the term "engineer" and "engineering." The term that bothers me the most is "value engineering." There is, in fact, no engineering that occurs... it is simply a contractor's idea to reduce cost. This typically requires re-engineering on our part.
My goal...
I am a registered professional engineer in a handful of states. Recently our office came across some articles that reference ethical issues surrounding the use of P.E. after the engineer's name. The idea is that the use of these initials can be misconstrued as registration in a state that an...
When are you considered an SE? I have passed the Structural I exam and I am liscensed in VA. Do I use SE or PE? Do I need to pass S2 in order to be an SE?
Thanks for your help.
When designing a basement wall with at-rest earth pressure, what design span is typically used?
Top of SLAB ON GRADE (or sometimes just grade) to brace point above
or
Top of FOOTING to brace point above.
I have used the top of footing for design of flexural reinforcement, but then considered...
THis method does not discribe how to adjust strength for transverse reinforcement. Surely rebar ties would help strengthen the edge faces. Does anybody have a good reference for this concept?
Is there a section of the ACI code that covers the developement of smooth hooked bars in tension? I am unable to find any information on hooked bars beside the section on standard hooks... which are deformed bars. Any information on this subject is helpful. Thanks.
