    SASSI software: where to find it?

    Hello, I'm a structural engineer which is interested in SSI: I've seen SASSI software, but at the moment I can find only commercial versions (e.g., ACS SASSI or the Ghiocel one), which are derived from a certain SASSI2000/SASSI2010 academic versions. However, I'm pretty sure that should exist...

    Ansys Beginner - Not FEA Beginner

    You can go there: https://sites.ualberta.ca/~wmoussa/AnsysTutorial/AU/AU.html There's plenty of examples, where you can learn apdl syntax. They're usually at the end of each page. Example: https://sites.ualberta.ca/~wmoussa/AnsysTutorial/CL/CBT/Truss/print.html Then I suggest you to use Ansys...

    WELDING - Bolt 8.8 and S355

    Hello, @r6155: it's an horizontal pressure vessel. There is a baseplate casted in concrete and then the equipment is bolted on this baseplate. The anchor bolt which I'm talking about in this thread is the headed stud that will be inside concrete and CANNOT pass through the baseplae, so it's...

    WELDING - Bolt 8.8 and S355

    Hello to all and many thanks for your active participation, it is really great! @desertfox: the article you linked is very interesting. I'm not expert of US steel grades, but it seems that exists some steel bolts with an high enough elastic limit that in case of necessity can be welded. If I'm...

    WELDING - Bolt 8.8 and S355

    Then why if you know very well stud welding you say "never weld a fastener"? Really, I don't understand.

    WELDING - Bolt 8.8 and S355

    Hello, @r6155: yes, that's why I asked. If I already knew the answer, I wouldn't ask... As I said in my first post, I've always heard that: NOT WELD high grades bolts. But it is not enough to me, and since I was exploring alternative ways, I wanted to know more and reasons. Desertfox has been...

    WELDING - Bolt 8.8 and S355

    Hi desertfox, Yes, the S420 steel will be the new steel class for round bars. If some expert gives me an advice, I follow that advice, I just like to comprehend the physics behind and its real meaning, besides prescriptions and norms :) Thanks another one time!

    WELDING - Bolt 8.8 and S355

    Hi desertfox, I don't understand: in the last message, I said that I've abandoned the 8.8 class and that I've chosen another solution, which is rolled bars in S420ML steel, welded to a S355J2 plate. The S355 is described in EN 10025-2 as a weldable steel, and S420ML (from EN 10025-4) is known...

    WELDING - Bolt 8.8 and S355

    UPDATE: the EN 1090-2 §8.2.1. forbid to weld threaded bolts.

    WELDING - Bolt 8.8 and S355

    Hi desertfox, Another thank you for your answer. Unfortunately, the issue is that design is already fixed and cannot change. If not, I would simply increase diameter and/or change anchor arrangement in a more convenient way: I'm not a fan either of 8.8 grade solution, but one should explore all...

    WELDING - Bolt 8.8 and S355

    Hi desertfox, Thanks for your answer, and I agree with you that weld can alter locally bolt mechanics characteristics. But these bolts will be some tie rods in concrete, and not a steel-steel connection, so they will be loaded only in tension and their maximum expected stress is about 380 MPa...

    WELDING - Bolt 8.8 and S355

    thread725-449248 Hello, Since I've found a thread which treated this issue but it is closed now, I'd like to readress this question and add some reflections. In fact, I've digged the EN ISO 898-1, EN 683-2 and EN 10025-2. I've found for example that the S355, by the IIS formula, that the...

    SASSI 2000 - Berkeley Version

    Hello, Do you have any idea of where it is possible to download SASSI 2000? Not a commercial version as ACSASSI and similar, but a freeware version. I think that as for other codes like SHAKE91, FLUSH etc. there is the possibility to obtain the original version. Or not?

    Self weight in Ansys

    I want to specify that gravity might not be the design load for mechanical purposes, but in CW it can be more than relevant. But yes, the gravity is not added by default because it is a general purpose FE software, so if you want for example to consider a different gravity value, or a more...

    Thick shell intersection - How to evaluate the stiffness increase?

    @FEA Way: yes, absolutely, but this is equivalent to model an infinite local stiffness on the overlap region, right? I'm doing this simplified example to extend it on more complex geometries, where the simple offset is a bit more complicate to manage.

    Thick shell intersection - How to evaluate the stiffness increase?

    Hello, I've got a general question about FEA and shell intersection: considering the case of two large concrete walls (say about 2 m thick each) that create a T intersection, a finite element model that uses only thick shells elements should consider the stiffness increment due to superposition...
