RAM Concept - Large moment at the edge of mat slab
I am designing a mat slab foundation beneath a series of concrete shearwalls using ram concept. At the corner of the mat slab, an excessive amount of program reinforcement is being specified, and in looking at the section analysis, is due to a very large…

Excessive Excess porepressure in foundation after embakment reinforcement
I am currently modeling the reinforcement of a tailings dam. I'm using the Hardening Soil Model for the foundation materials and we are running a fully coupled flow-deformation analysis. We are observing that during the reiforcement phases the model is…
Foundation-Plate Mat Support versus Plate Pin Supports
I have been designing an RHS with a base plate and gusset stiffeners. I've used master-slave command for the location of my loads and used Plate Mat Support as supports. The error was always "ERROR IN SUPPORT INPUT OR THERE IS NO SUPPORT INPUT. ANALYSIS…
Soil model
Hello,
I have come across a problem where the raft foundation is resting on clayey silt. Ground water table is not encountered and soil at the site has a free swell index of 140-210 at 2.5 to 5m depth from EGL and foundation is at 3m below EGL. what…
RAM Connection Base Plate Anchor Bolt Force Distribution
Why is it that in RAM Connection, Base Plate module, fixed biaxial, that tensile loads in anchor bolts aren't distributed based on their location to the load application point? For example, if I have a column with a 2x2 anchor bolt layout, with one of…
Interpreting Foundation Settlement Foundation Module
I am running an isolated footing design in the RAM Elements Foundation module, and for the controlling load combination I am getting a negative settlement and am looking for assistance with interpretation. The loading is eccentric and 70% of the footing…
Hoek-Brown - pore pressure and Safety Factor
Hello everyone,
My first question here in the forum!
I'm modeling a set of foundations on weathered granite and I'm using the Hoek-Brown (HB) model. Everything in the material model works perfectly fine, however, three questions regarding the material…
Tunnel _ volume strain input
Hi all, I was modelling the volume expansion (due to temperature change) by inputting the volume strain of material directly. But when I consider the tunnel, I cannot input the volume strain value to the lining ( plate material), so it shows the wrong…

vba for creating and assining elastic mat
Is there any code to create and assign elastic mat footing in STAAD by OPEN STAAD commands?
Staad Foundation
I know that Staad Foundation assume the soil with an elastic performance to do the analysis and design for a superficial foundation. But, we have the possibility to change this and work with an inelastic performance for the soil?
SHEAR Failure of RAFT in STAAD PRO - need asap help
Hi, I am modelling a substructure in STAAD Pro and after application of loads when i ran analysis i got my raft failed in shear. my allowable shear is 0.675 KPa and the actual shear stress is 1.5 KPa, i have ignored the plates under the columns and even…
why Fy = 0 when i give a point load on foundation
I give -20 kN/m (point load) on my shallow foundation but when i calculate it. there is no any Fy apllied to my project
ps. I activate oint load already
Thank you
Mat analyzed in STAAD.Pro and designed in STAAD.Foundation Advanced
Dear Colleagues,
The method as per the link ( Mat analyzed in STAAD.Pro and designed in STAAD.Foundation Advanced ) would have been useful for structures such as Buildings with Basements, Underground Tanks / Pits... etc wherein such a structure as a…

Stimulation of allowable bearing pressure of square footing from the Plaxis 2D analysis
Hi all,
In order to find the allowable bearing capacity of the footing, we can use prescribed displacement (25mm) and fins as shown below.
But here it represents the strip footing as length inside the model is infinite. Based on the pressure…

Is there a way to define a space which water passes through it? which command and material model is available for that purpose?
I defined a space which represents air in foundation by using polycurve. But PLAXIS-3D is a finite element model which water freely does not pass thorugh it. As a considering Plaxis asks me to define an material model and properties, how can i perform…

I have a question regarding pad foundations in RAM, I am new to RAM, have used it for suspended slabs but not for slabs on ground
The reason for the model (and not simplified software) is because the footing shape is irregular with 5 columns from the…
