Having read your comments, I'd like to add a few lines:
- Earthquake loading is cyclic, so degradation is expected, but
- Earthquake loading is dynamic, so a more rigid and viscous response is expected. These two issues are mentioned in NCHRP 461, and I understand that in the "Simplified...
I am used to calculating the modulus of horizontal subgrade reaction for piles which is asked to me by my structural engineering mates. I use different formulae and correlations already discussed in other threads about this subject. However, I cannot find design rules to establish that modulus...

Hi everybody.
I'm involved with a project containing MSE mixed abutments on piles going through the MSE wall, and once read this thread and some documents by FHWA, I understand there are two construction options: either drive piles prior to face construction or use hollow sleeves...
I've added some coordinate/grid systems to a model I'm working on. I need them to define a complex geometry (holes in shells). However, the GLOBAL system is always displayed. How can I choose the coordinate/grid system I want to use?
Thanks
Sorry, there is an old thread about this:

The solution given there is complex to apply.
Any other ideas?
Does anybody know how to apply a radial joint pattern in SAP2000?
I'm modelling a circular slab on grade supporting a stockpile (cone shaped load). I've defined the structure but cannot assign a cone shaped joint pattern to the joints to get a cone shaped load since, even though I'm working on...
"Column strip is a design strip with a width on
each side of a column centerline equal to 0.25xl2 or
0.25xl1, whichever is less."
¿What happens when L1 is shorter than L2 but L1 is not equal in successive spans? ¿Should I use variable column strip width? In this case, ¿what would be the width...
Does anybody know if there is an available model for Plaxis 8.6 according to Hoek-Brown model for rock masses?
In one of the latest bulletins they said this model would be available by the end of this year. I've checked that it is already available for the laboratory tests module (VIPlaxis...
