Hi All,
I have to design a welded tubular connection that connects 2 tubular members (like a T shape) in an off-shore platform jacket. One of the tubulars is a column (2225x80mm) and the other is a brace(1100X25mm). The brace exerts torsion on the column beside in-plane and out-of-plane bending...
Hi All,
I have to design a tubular connection that connects a tubular stub with a Jacket Leg (tubular with thickened part). The tubular stub exerts torsion on the jacket leg (in addition to the axial, and bending moments). As far as I know, according to AP-RP2A-WSD, tubular joint capacity...
is there a way in SAP2000 to make analysis for the model to report specific joint displacements only without stresses and forces being reported for the whole model members. This is required sometimes in time history analysis where the required output takes a huge amount on the memory and the...
Hi jthrncir :
I think it is better to perform DLE analysis. This is because of 2 things:
1. in API RP 2A Sect 2.3.6.b.2 states that "platform design would normally controlled by storm or other environmental loading rather than earthquake", this means it may be not adequate for special rare case...
I am preparing to take FE exam next April. I have my undergraduate engineering program out of US, So, I think I have to get my credentials evaluated from NCEES credential evaluator.
I want to know how long does it take for NCEES to evaluate my credentials? (I searched their web site for this...
Hi,
Are there any manuals or text books giving solved examples for API-RP 2A? I am engaged in an offshore design job and want to study about “fatigue analysis and design” for fixed off shore platforms.
Any book or web site links will be a great help to me.
Thanks for your help
Thanks (ATSE) and (271828) for your help, I appreciate it.
I am searching for the basic equations that control the relation between the equipment frequency and the structure frequency.
Do you know any reference discuss that issue (book, website, paper, …)
Note: I am not sure if there will be...
Hi,
I want to check floor vibration criteria for a platform (industrial structural steel platform) carrying an equipment producing vibration.
Is there any one knows how to make a floor vibration analysis for a platform mounted by equipment?. The equipment manual provides all important...
Thanks hokie66 and PSlem for your interest,
Actually I am supposed to prepare a presentation on the aluminum and alumina industry structural buildings, since my company is targeting to take new project regarding this field.
The buildings that I am interested in are the SAG Mill (grinding and...
Any one can help me to find any material regarding structural steel buildings in aluminum plants, or give any website which provides information about the structural concepts used in Aluminum plants buildings.
Thanks for your help
Would anyone help me to find the latest version of ASCE publication with the name “Guidelines For Seismic Evaluation And Design For Petrochemical Facilities”, which prepared by the petrochemical committee of the energy division of the ASCE.
Thanks in advance
I have a discussion with my coworker about footing design subjected to vertical forces due to D, L, and E loads. The soil report permits a 1/3 increase in allowable soil stress for transient load conditions.
I say the following points,
1. To get the max expected soil compression stress and the...
Item 11.7.3 in ASCE7-05 says “Any smaller portion of the structure shall be tied to the remainder of the structure with elements having design strength of not less than 5 percent of the portion's weight.”
What is the relation between the 5% portion's weight and the element design strength?. Can...
