From that standpoint you're in good shape then. We have issues with it because we have a large backlog of previous work in our current software so to switch would mean some "tricks and techniques", macros, etc. that we've established with the current software would be lost or have to be...

I've seen this happen with other analysis software I've used in the past. I've purchased and invested considerable time in working with a software package only to find that on a new and "improved" edition they've removed either functionality and/or codes. I worked with a certain piping...

Thanks! I'm going to take advantage of your offer and get in touch with you later this week as I have a couple of questions.

Hello, I'm looking for some help on theoretical background on a subject. I'm performing an elastic FE analysis to Part 5 of Section VIII, Div. 2. I have a government reviewer (Canadian CRN stuff, another long story) who is insisting that analyzing for hydrotest conditions is required under...

Hello, We're starting to use SAP2000 for design of framed pipe supports to building code requirements (NBCC). I've got horizontal bracing in my design but the program keeps assessing it as if it is a beam. I can't get it to consider it a brace. I'm not having this problem with the lateral...

Hello, I'm relatively new to using STAAD but I seem to be having some trouble generating the loads under for NBCC 2005 (Canadian Building Code) for seismic loading. I am trying to enter them in using the setup explained in the technical file para. 5.31.2.11 but am not having much luck. The...

Hi, I have a question about what a certain clause means in N285.0-08. The clause has to do with the information required in the overpressure protection report. The clause is 7.7.7(c)(iv)(3) and asks for "efect of variation in operating time". I'm not sure what this one means. I think I've...

Thanks. That's a good idea, it's pretty much the only option right now.

That's funny, I've got it here right under F62. I'm using the 2007 Edition if that helps.

Thanks metengr. This is where my confusion is coming from. I was looking at the forging for B649 in B16.5. Also, I realize in Part D there is no F904L listed, but it is listed under SA-182 in Part A. The people I am working with seem to be using the allowables and pressure ratings from B649...

Hi, I'm having a problem and I'm hoping someone on the board can give me a hand. I've got a client with a design which has a flanged item constructed of A182 904L for a B31.3 component. I've looked through the allowables from App A and not found it and also Section II Part D with no luck...

Hi, I'm currently modeling a piping system with several expansion joints in it. The expansion joints are covered by metal braided hose to prevent excessive longitudinal expansion. I'm having trouble coming up with a way to model the hose. I've modeled expansion joints with tie rods a number...

Thanks, that's what I think too. Someone raised the question and nobody was sure of the answer. The fact that an absolute vacuum would result in a zero value using psia for pressure also makes no sense to me. Just wanted to get a second opinion from someone who has used this clause more often.

I was wondering if anyone has used the external pressure calculation for unreinforced bellows in Section VIII, Appendix 26, 26-6.5? There is a disagreement about whether when the Code asks to use the absolute value of the pressure in the internal pressure equations whether it means psia or the...

Thanks for the suggestions prost and torpen. They'll really come in handy. Prost, I played around with AFGROW over the weekend and I really think it will help a lot. Thanks!

I'm going to be working on a problem involving the propagation of a postulated crack in an unpressurized cylinder due to cyclic loading. I'm going to need to calculate the growth rate and the point at which the crack becomes unstable. I've never performed an analysis such as this in ANSYS and...

Hi, I'm having a little trouble. I got a set of transmitters that are to be use in a B31.3 system. I don't have much experience with these types of connections and I've gone through B31.3 looking for some sort of reference to them, but had no luck. Does anyone know if there is a reference to...

Actually, that's exactly what I am (except the Frech part) and the service I am providing. The TSSA has pulled this Code Case out, which they haven't before, and are refusing to register the design. I've never had this problem before. I'm just trying to get some ammunition to go back to them...

U-1(a)(3) says that you can't use engineering judgement to supercede mandatory requirements or specific prohibitions of the Code. Is a Code Case considered a mandatory requirement, or is it advice from the Committee on recommended practice, but not necessarily madatory? Just curious. For the...

Thanks! I think that may be it. I've been looking for over an hour for that. 1000 yard stare I guess.
