Thanks C2it , I think it may be the anchor and treating as fully rigid , I will play wit it a little more M1 Engineering http://www.m1engineering.ca

DSB123 Was checking forces and moments(not stress) on terminal points , sometimes on small piping that is not critical I do quick checks using another program. This time I did a check and found Ceasar was off, so I checked with a third simple finite element model now I have the structural and...

I was doing some test cases with other structural programs, basically ran a pipe arrangement with 3 programs ( one of which is CII). The results of the two of the programs were very close 2-3% but the ceasar results were off by as much as 100% . Any ideas what may cause this , I have always just...

Is there anyway in Caesar, to change the Code Year to use previous Codes. M1 Engineering http://www.m1engineering.ca

Sketch attached M1 Engineering http://www.m1engineering.cahttp://files.engineering.com/getfile.aspx?folder=a0e15282-0ad9-4bc5-8c19-3bd2093cd0de&file=ladder_sketch.pdf

I am looking at a step over ladder used to get over a conveyor ( top of walkover 50" from grade). Walk up one side , 2 1/2 ft platform on top and walk down other side. My concern is whether it has to be restrained from overturning. The ladder is considered portable and get moved a little along...

I am looking for some clarification on moment vs shear base connections. I typically used to treat base connections as shear and would design the base plate as such. On a more recent project we designed the base plate as a moment connection. My question is if I design a base plate as either...

doct9960, Not sure how my customer ended up with this arrangement, we asked the same question but didn't get a good answer. Only that manufacturing on the tank has started. Apparently their competitor uses this arrangement and they followed suit. Registration in Ontario Canada requires PE...

x x x xyyyyyyyy x x x x x x x x x yyyyyyyyyyyyyyy My best shot at a sketch , the x are the head ( although it is actually eliptical) and the y are the nozzle Thanks...

If anyone can give me some advice on how I can add a sketch into the forum it would be great, a picture explains it so much better. This case the head is for an 8" pipe and the nozzle is 2" pipe. Thanks M1 Engineering http://www.m1engineering.ca

Similar to Appendix L 7.7 , except 7.7 shows a hillside connection into a shell. This connection is into an eliptical head and it is not entirely in the crown radius section of the head it runs through the knuckle radius , including a little of the straight ( that fits to the cylindrical shell)...

I am reviewing a pressure vessal calculation for a customer that has a connection into an elliptical head. Rather then the nozzle coming in perpendicular to the crown of the head it is coming in at 90 degree. Example the vessal is vertical and the connection is horizontal, perpendicular to the...

Thankyou Prex and GenB for both your replies, I think I am OK now , although I believe the code could be clearer on what is considered a flanged-in manway is ( Section VIII has a sketch but they call it a flued opening). I also agree with GenB that the calculation needs to reflect a welded ring...

I am looking for some help interpreting the required thickness of a semielipsoidal head with a manway. In the past we sized the head thickness based on a blank unstayed head and provided reinforcement for the manway opening ( Re PG-29-4) But we were recently reviewing a new customers...
