Hi All,
I looked everywhere but I couldn't find any specific information, and when I found some info they were kind of contracting each other (or maybe it would be better to say that they did not agree).
1 - do couplers always have to be at slab mid depth? (I don't think so).
2 - do couplers...
Hi all,
I have a complex model with a weird shape that gives me problems.
I managed to run the Modal analysis using Eigenvalues algorithm but the mass participation ratios comprise a big component of RX RY.
According to ETABS analysis reference manual UX UY UZ RX RY RZ are about the center of...
Hi all, I am relatively new to ETABS although with extensive experience in FEA, and I am a bit puzzled about the results that ETABS provides compared to what is described in the CSi documentation.
I am analysing an eccentric building where the first mode is torsional (activates 37% of mass) and...

I have created a spreadsheet to calculate the embedment depth of a bored pier in sandy soil.
I get same results as per Design example 1 for formulas B2 and B6, but different values for B4 and B5.
There is something not quite right in formula B5; the units are not right...
Hi everybody,
I am fairly new to RAM Concept but I already got hands on most of the Layers to check.
I am currently dealing with a flat slab with few transfers. It is ok for strength, but has few localised ductility issues that I can't solve.
I tried to reduce the number of strands (to the...
I appreciate any opinion or suggestion on the following matter:
I have to design a cantilevering retention system for a 7m excavation on a fine to medium clayey sand at founding level.
Unfortunately the geotech report specifies just the soil pressure profile to adopt for the structural design...
Hi everybody, please help me cause I'm getting frustrated with all these different explanations!
I read a lot about stiffness modifiers for shear walls (CSI website, ATKINS manual, Eng-Tips forum threads....), but I have some doubts about what they report because they say different things, and...
I hope someone had ever though about this:
clause 7.2.4 bursting forces have to be checked for SLS and ULS using two differend divergence angle, 26.5 for SLS, and 11.3 for ULS.
Say that for a strut action of C = 1 KN, the ultime action is (average) C* = 1.35 C, and applying the divergence angle...
Hi mates,
i'm new to this forum, and i'm new too to pre-stressing and post-tensioning(:I, so please be patient :-)
I'm designing PT slabs with RAPT and i can't find anywhere information about how to define the minimum reverse radius for tendons.
I mean, is there a thumb rule to decide the...
