Also, just responding to BAretired, you said there are no loads on the sloping member, what if the two beams are technically separate? and the sloping member is welded to the left end of the beam, wouldn't that sloping member technically be under some load?

To be honest, I'm approaching this problem as fixed supports because I'm checking to see if the welds will be able to hold the structure with applied load, so I would need to know the bending moments at supports A and B and compare it to the welding strength at both locations.

The joints are both welded, thus it has to be considered as fixed supports. For doubly redundant (I assume this means second degree of indeterminant), how would you approach this problem? If I make bending Moment at A as a unit of 1, wouldn't I still have too many unknowns?

Hi everyone, I hope this is the right place to post this question, but I'm wondering if the free body diagram below can be solved? Or would it be indeterminate? See below for picture. The two beams are angle irons. Assuming I know values for forces P1 and P2, lengths L1 and L2, is there a...

Hey JStephen, So wouldn't using 5.10.4.4 be a conservative approach? Since it assumes uniform loading throughout the entire length. I'll only be looking at the area of the nozzle and its repad.

Thanks guys, What do you guys think of my approach as follows: Section 5.10.4.4 of API 650 provides calculation on rafter spacing. Is it acceptable for me to work backwards if I know the maximum roof plate span (6.5' in my case), Fy being 30,000psi, and the corroded roof thickness, and try to...

Hey everyone, Just wanted to see if anyone has ever done calculations or has experiences on allowable load for a roof nozzle on an API 650. Any help is greatly appreciated. I'm just unsure where to start. Thanks,

Thanks everyone, IFRs - I have yet to calculate the emergency venting requirement, will do it shortly. I assume an emergency vent is required to satisfy/meet the emergency venting requirement on its own? As opposed to adding all the other open vents to see if it exceeds the emergency venting...

Hi everyone, Does anyone have experience in completing API 2000 calculations? I am just a little confused on what my next step would be. I was able to calculate the normal inbreathing and outbreathing calculations for a tank I'm working on. (840.1Nm^3/hr for inbreathing and 431.2Nm^3/hr for...

Hi everyone, I have a question regarding Welding Performance Qualifications as per ASME Section IX. Let's say a company has an approved Welding Procedure Specification. Welders have their own Performance Qualification Cards with essential parameters. Do the welders have to be tested to the...
