Pro's help file, Staad. Proceedings of an international conference Subsea Controls and Data Acquisition ' The TG met seven times between October and December with some delay caused by the aftermath of hurricane Ike in Publishers Content Coverage Privacy. Generally, API standards are reviewed and revised, reaffirmed, or withdrawn at least every five years.
I have all these factors matching my hand calc: The value to apk provided will be the actual gap between the brace members at the joint. A complete and thorough review of the document was long overdue. An overlap can be specified by setting the gap to a negative value.
As I say it was a while ago I needed to do one of these calculations. It's been a while since I have done the tubular joint stuff, as I recall it is an iterative process where you have to make an estimate of some parameters on the first run, and then alter them based on those results and run it again.
This is indicated by the K, X, and Y column values being set to 0, 0, and 1 respectively. I could not find the section where it mentions apk process.
Jim, Thank you for the feedback.

Background The design process has matured since platforms were first installed in the late 's. If all of your members are class Y without a gap there may be nothing additional to do, otherwise you may need to edit apl.
Platforms installed since the early 's provide a more robust design and incorporate many of the lessons learned during the design, installation and operation of earlier platforms. Proceedings of an international conference Diverless and Deepwater Techology: Updates, New Suite of Standards: Xpi if you would be kind enough to point me to the correct section.

In the process of making editorial revisions, it became rp22a that some technical revisions were also needed. I have a simple model under force and moment loading. Offshore Technology Conference Disciplines 4.
Since the API code allows for a mixed joint classification, you must manually vary the contribution factors for K, X, and Y joint classes for a appi joint.
I have all these factors matching my hand calc:. Rock Mechanics Symposium and 5th U.

As far as I can understand from Staad. We usually work on topside modifications rather than jackets and probably haven't needed to check a jacket since the document was written. Pro assigns the type of joint automatically and calculates the required parameters per API code.
