wo-chamber tank and problem with wall between chambers

Anonymous — Tue, 15 Nov 2016 23:39:57 GMT

I have a problem with the program of your company Robot Structural 2015 - Student version.
I am at the stage of project execution study (two-chamber tank) and I want to ask 4 cases:
1. the two empty containers - no problem
2. both tanks full - no problem to choose the load, but now begins the stairs:
3. The first tank is empty even I can manage to do, to decide the appropriate local coordinate systems, so that the hydrostatic pressure displacing me from INSIDE the wall.
4. move on to the second chamber, but the problem is with the middle inside wall (separating the two chambers), because it has set the local coordinate system and I can not move it, and the shift in the case of the third change my direction of hydrostatic pressure. I tried it on the wall put under pressure in the Z direction, but then pressure acts "upside down," which misses the point.

Please let us know how to do that in the last two combinations my walls were pushed out from the inside by the pressure.

You can change (reverse) the direction of hydrostatic load by defining the weight of the liquid as positive or negative value.

Panie Arturze, widzę, że jest Pan Polakiem, więc pozwolę pisać w języku polskim.

Mam teraz problem z wymiarowaniem żelbetu, a mianowicie gdy przechodzę do > wymiarowanie żelbetu>płyty-zbrojenie rzeczywiste, a następnie chcę otworzyć okno "parametry zbrojenia", to wyskakuje okno, które załączam w załączniku. Tak jakby programowi brakowało czegoś i chcę to zainstalować, ale totalnie się zawiesza i nic nie da się zrobić.

Dobra udało mi się Panie Arturze, wystarczyło, że zaktualizowałem wersję i teraz jest w porządku.

Panie Arturze,

Czy wiem dlaczego w zbiorniku zadałem podłoże na płyte denną (obliczyło mi współczynnik Kz), ale jak włączam obliczenia, to wyskakuje mi brak podpór i dopóki nie zadam gdziekolwiek podpory nieprzesuwnej, to nie zrobi mi obliczeń... No a o to wlaśnie mi chodzi, żeby nie było nigdzie żadnych podpór.

Pzdr

To ostrzezenie nie blokuje obliczen (mozna je zignorowac). ale wazne jest zeby byly jakies podpory lub podloze elestyczne blokujace przemieszczenia w poziomie (nie moze byc samo podparcie w kierunku Z).

Czyli na ściany też powinienem zadać współczynnik Kz?

Panie Arturze,

A co z takim problemem? Przesyłam zdjęcie w załączniku.

As it seems to become a longer conversation I'd propose switch back to English so that others could get the valuable information as well. As the RC Wall module in Robot supports only NF EN (French EC2) code you have to either use this code or design the wall in the RC Slab Reinforcement module instead which is the recommend approach for walls with out of their planes loads (pressure). This has been explained during the 5th RSA webinar which recording is available from:
