Good Day,
ETABS shows different shear + torsion reinforcement areas between what is displayed on screen using "Display Design Info" and what is shown in the Beam Design Summary table. Any idea why that would be the case? Also, how can I get the values shown on screen using the tables or any...
Good Day,
I have modelled a square manhole with SAP2000 as a shell and opted for the one layer in the reinforcement design under the area section properties. I am now unsure how the N11 and N22 are calculated since the technical notes manual of SAP only mentions the formulas for the...
Thank you guys for making this forum so helpful!
Indeed Doug I had missed aligning the subdivision of the base with the walls. It is now behaving as expected.
Best Regards.
Thank you guys for your help. Indeed the issue was with what bones has said regarding the division of panels. I divided up the panels further and the numbers seem more reasonable now.
I do have another question now though, why is it that the stresses on the XY plane differ from those on the YZ...
Thank you for your reply.
Kostast: Indeed it is an underground chamber, surrounded by soil. I have applied (to the walls from the outside) a triangular load that peaks at 57.62 kN/m2 and a factor of 1.7, such that (combo1) should be 97.95 kN/m2.
steveh: I am not sure I understood your point...
I am trying to design a RC square manhole that is 4 m high and 1.8 m wide. I modelled the square 'tank' like manhole in SAP2000 and found the absolute maximum moment to be about 1.1 kN-m. However, when I used the formula for a fixed wall with one free edge from "Roark's formulas for stress and...
