Ram Concept Implementation of ACI 24.2.3.8 Ig for PT Slabs
How does Concept implement section 24.2.3.8 of ACI318-14 which permits the deflections of Class U slabs to be based on Ig? I am working on a model where the plots for Ieff/Ig for the load history deflections indicates significant reductions in stiffness…
Ram Connection_Outdated Concrete Design Code [US]
For a column base plate, the Steel Design Code uses the up-to-date AISC 360-16. However the Concrete Design Code is still the outdated ACI 318-08. I understand not much has changed for the anchorage provisions in the ACI other than it being reorganized…
RAM Concept: Excess temperature and shrinkage reinforcement (DET/7.12)
I am seeing excess temperature and shrinkage reinforcement. The criteria that's being displayed is Det/7.12. In the circled area the middle strip width is 10'. Per 7.12, for a 10" slab, I would need 10*12*10*0.0018= 2.16 in^2. The user input reinforcement…

Outdated References in RAM Connection
Does anyone else think that when a company says they have incorporated a new design code into their software, they should probably update their code references at that time? Seem reasonable to anyone else? Instead, Bentley still references the 2005 seismic…

Ram Concept - Implementation of ACI 318 18.9.3.3
ACI 318 18.9.3.3 includes an equation to calculate minimum reinforcement by the maximum gross cross-sectional area in two orthogonal directions. Is this implemented in RAM Concept? I could not verify that it is and could not find a code reference indicating…
Column design using moment magnification
Good day,
I performed a concrete design in STAAD Pro using the moment magnification method, however, there seems to be an error as the Slenderness ratio (Klu/r) reported by STAAD is much smaller than expected. For example, Klu/r reported for Column…
Does STAAD design for CONCRETE SPECIAL MOMENT FRAME as per ACI 318M-11 ??
Hi,
1. Does STAAD take into account the ductile detailing provisions of CHAPTER 21 of ACI 318M-11, while arriving at the reinforcement area and stirrup area ??
3. If those provisions are available, how does STAAD identify a SMRF or IMRF or OMRF in…
