ParticipantHello, I’m performing SLS checks with the concrete module and I have encountered some problems with the cracking verification. In the image attached there are two sections of the same pillar, at 1/4 (at the top) and in the middle (at the bottom), same load condition, with the two results of the cracking checks in red. The tensions are pretty low in general, but the section which is mostly compressed is the one with the worse rebarDiameterRatio. It looks like something’s not working properly.
I’m using version 2.3 and concrete module.
Thank you,

NextFEM AdminKeymasterHello,
the section which is mostly compressed is the one with the worse rebarDiameterRatio maybe due to the composite bending you have in the bottom pic (hence corner bar is more stressed).
Could you share the model by uploding it at the bottom of Support page?December 16, 2024 at 4:04 pm #5770Elisa Monti Di Sopra
ParticipantThank you for the answer, but I’m trying to upload the file but it says “upload failed! File not allowed”…

NextFEM AdminKeymasterThanks, we checked element 623 in v2.4 and we confirm there’s no issue. Compared with v.2.3, the current version has been revised for SLS verifications, both for Eurocode and Italian codes.
As a workaround, you could run the checking set “NTC_CA” included for SLS combinations.December 17, 2024 at 12:59 pm #5793Elisa Monti Di Sopra
ParticipantOk but can you check it for version 2.3? That’s the one I have. Using NTC-CA the rebarDiameterRatio is even worse, 1.722.

NextFEM AdminKeymasterVersion 2.3 was accounting a reduction factor by means of Eurocode 2 on quasi-permanent combos, which is not actually considered in NTC. Our internal rules prevent us to act on past versions (v2.3 does not receive updates since the end of June), however we understand your needs and we decided, exceptionally, to release a small update for your version. Please check for minor updates from inside the program.
