During design of pressure vessel, I came across this issue number of time. Unfortunately, ASME VIII Div.1 doesn’t give a clear picture, whether to add the undertollerance in the min. required thickness as calculated by ASME VIII Div.1 ASME VIII Div. 2, give a clear cut understanding on this issue, can clears all ambiguity. (Clause…
Whats is Earth quake factor? and how they affect the calculation? Their are numerous papers on this, and they are equally qualified to tell you what is earthquake factor all about… but what mater to me is.. how do they do it! As far as India is concern..The earthquake of 26 January 2001 in Gujarat…
It is customary for most vessel designers to establish the minimum vessel shell and trend thickness according to the pressure temperature conditions and then calculate the thickness required at the bottom head seam due to bending moments imposed by wind or earthquake forces. Stresses in the longitudinal direction are involved nod the following notation maybe…
Earthquake loading – Brief
All designers are accustomed to evaluating moments due to eccentric and wind loads, but there are a few who may not be familiar with the method used for estimating moments due to earthquake. Therefore, the following brief outline is presented because this method is recommended as a design procedure for vessels where dynamic considerations are…
