    European HE Beam - HE160(B)

    patswfc, Thank you - good advice. The site MIN design temperature is -15C. We talked to the steel manufacturer and we will order impact testing: -20C / 27 joule. One other related question for you if you could offer your expertise. I just wanted to understand more about the usual protocol...

    European HE Beam - HE160(B)

    Hello, I am working on an international project and considering using the European HE Beam - HE160(B) for a skid frame. The steel was identified as: HE160(B) S275JR04. I found out the S275 refers to 275 N/mm2 Yield Strength. I had no success finding information on the "JR04". Please advise...

    20" x 12" Reducer for 720 psig design pressure

    Thank you all for the replies. Will consider stronger material and other suppliers (I took at "face value" what the purchasing agent said).

    20" x 12" Reducer for 720 psig design pressure

    Hello, We need a 20" x 12" Reducer for 720 psig design pressure @ 120 F. Piping is A106 Gr. B. Per formulas in B31.1, this requires Schedule 40 on the 20 inch and STD wall on the 12 inch. We found out that "purchased" fittings above 12 inch are only available in STD wall and for the 20 inch...

    NFPA 101-2015 Section 7.3.3.3

    NFPA 101-2015 Section 7.3.3.3 states: "Stairs and ramps that continue more than one-half story beyond the level of discharge shall be provided with an approved means to prevent or dissuade occupants from traveling past the level of discharge during emergency building evacuation." Please advise...

    Stress In Thin Rectangular Thin Plate with 3 Edges Fixed and 1 Free and with Applied Moment

    I was trying to find a formula for the stress in a thin rectangular plate with 3 edges fixed and 1 Free with Applied Moment. I have done a FEA run but would like to back it up with a "classical hand stress calculation." I tried Roark's formulas for stress and strain but did not find this case.

    EN 13480 with ASME SA 312 TP 316/316L

    XL83NL, thank you for the reply. Yes, I noticed EN 13480-2:2012, Section 4.3.3 allows using other materials if approved with PMA. Our pipe stress package CAEPIPE will run under EN 13480 analysis with either 316/316L or 1.4401/1.4404 allowable stresses - so I was considering filing both these...

    EN 13480 with ASME SA 312 TP 316/316L

    We have a project where the preferred piping design code is EN 13480 which requires the use of "harmonized" steel. However, our client has accepted the use of ASME SA 312 TP 316/316L from Particular Material Appraisals (PMA). So my question is: can we still design and inspect to EN 13480 and...

    ASCE 7-05 Chapter 12-15 Applied to Skid Based Equipment

    Thank you for the feedback wannabeSE. I was reading ASCE 7-05, Section 15.4.3 and it refers to Section 12.7.2 (as you mentioned) to figure out the effective weight W. In Section 12.7.2, Item 1, it says to use a minimum of 25% of floor live load in areas used for storage. The intention of this...

    ASCE 7-05 Chapter 12-15 Applied to Skid Based Equipment

    I am trying to learn about ASCE 7-05 Chapter 12-15 as applied to skid based equipment. Specifically, the lateral seismic base shear force depends on the non building structure operating weight. If the skid has a platform live loading requirement of 100 psf, should none, some, or all of this...

    High Temperature Steam Regulator

    Please inform me if you know of a steam pressure regulator rated for 680 F @ 200 psig. Most of the ones I have seen are only rated to 650 F.

    Parallel Beams Load Distribution

    dhengr, thanks for the points. Looking back I should have just asked for references for basic mechanics of materials theory on load distribution on parallel beams rather than advice on a specific layout. Certainly any such theory would depend on the layout. Are there any such theoretical...

    Parallel Beams Load Distribution

    Thanks BA retired. I did not notice that link at the bottom. The sketch is attached. The sketch is not a good 3D representation, but the condition is vertical lifting with the four lifting lugs...

    Parallel Beams Load Distribution

    Thank you for all the replies. In an attempt to make the question clear, I think I oversimplified it. I have a sketch but I can not figure out how to attach (I tried to search this site). I am sorry to ask in this forum, but how do you attach a pdf scan?

    Parallel Beams Load Distribution

    I am looking for a method to determine the load split between parallel beams in an enclosed frame. For example, consider a rectangular frame with W10 x 30 over the entire perimeter and W8 x 21 running lengthwise down the middle. Also, the top of the frame is covered with a thin steel plate and...
