Thank you very much! It is not as simple as you think. Refering to EN14015, Section 12, you can find some complicated formula for tank with circular cross section. Check the attachment please http://files.engineering.com/getfile.aspx?folder=54b34bbe-5304-42aa-9927-5c7571961418&file=B_2.pdf

Hello every body, Does anybody know how to investigate overturning stability of rectangular tank which is mounted on the ground with 4 legs? BR.

Thanks for your reply MJCronin. Unfortunately, the the client don't have enough engineering sight and knowledge. So, I have to prove for him that the joint is stiffened enough.

Hello every body, i have to prepare a calculation book for rectangular storage tank with following dimension (L * W *H) = 2500 * 2500 * 1500 Calculations for wall and bottom thickness and stiffeners size is base on this book : "Design of process equipment" ,By:Mahajan. I have to offer...

Thank you KootK. i talked to my colleague. i think he made a mistake. he is referring to standard API Bulletin 2V. he told me that one of the important parameter that affects buckling of stiffener is slenderness ratio. he concluded that since LTB (lateral-torsional buckling) and LB (Local...

OK, Thanks to BAretired and JAE for your useful information. from your explanation, i found that the probability of column buckling is zero. for column buckling, axial load is necessary. am i true? THX.

Hello friends, i have a question about column buckling. Assume a circular stiffened plate which is simply supported along its edge. a uniform lateral distributed pressure acts on the plate. The stiffeners are welded to the top of the plate.(I have attached the picture). some detail...

Hello every body, I have to present hand calculation for a rectangular storage tank. i have designed tank walls besed on Kanti.K.Mahajan reference book. I am involve designing tank legs. the tank is supported by 4 legs. loads are : wind, seismic, dead load i will be appreciated if anyone...

any specific standard? ASME,API,...

Hello every body, I have to design a support for an agitator. agitator mounting : Beam mounting Load: Static vertical force and dynamic bending and torque load any reference book (or software) which contain calculation example can help me.

I change the stiffener dimension to 50 mm * 10 mm maximum stress in Stifener : 14.68 Mpa maximum stress in plate : 3.33 Mpa the deflection of plate should not exceed 2 mm. Maximum deflection is 0.22 mm. So, the problem is solved! Thank to every body.

Thanks. Fortunately, it seems there is no probability of buckling. I will be appreciated if anyone help me for "AISC unity check".

Thanks for your reply sir, I have attached the picture for you. Ok, there is no probability for LTB. How can I check local buckling? I also need to know about "AISC code unity check". i am mechanical engineer. would you please tell me how to check unity? i know nothing about it. Best...

Thanks for your reply. a circular plate with thichness of 5mm which is loaded by uniform lateral pressure of 5935 Pa. 2 plate stiffener with rectangular cross section (100mm * 10 mm) are welded to the plate inorder to prevent large deflection. I have attached the picture. Material...

Hello every body Does anyone know how to design laterally loaded stiffened panel? Design considerations are lateral-torsional buckling and also local buckling. i am completely confused!....

API 650.

Hello every body, I have to design a support for a agitator which mounts on flat top cover of a storage drum. i have calculated dynamic force load, static load and dynamic torque load. Does anyone know any design procedure for agitator support? any book?standards?etc. Whats are design...
