I am trying to design a ground supported slab using RCDC and i keep getting this error. what is the work around. Thanks in advance

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…

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 However the Concrete Design Code is still the outdated ACI 318-08.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…

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…

I am building an Elements model to analyze and existing structure, specifically a concrete dome. Based on the existing drawings (which are from 1940), there is some intricate reinforcing detailed within the structure. There are reinforcing hoops which…

Are there plans to include ACI 318-19 provisions in any upcoming releases for the RAM programs? If so, is there an ETA on this? Our AHJ will be adopting IBC 2021 in a few months, but we need to have the ability to start designing concrete structures in…

Hello, I´m currently reviewing a Reinforced Building Design in STAAD.Pro CONNECT Edition and The Client asked for some information; more specifically, the Design Moments and Axial Forces for the RC Columns, so I went to look up the info in the Analysis…

Googevening, performing concrete slab verification with staad pro (ACI Code), I noticed some discrepancies between input data definition, as reported below: and output results obtanained from calculations are listed below: in particular the…

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…

Can Ram concept be used to design a monolithic Slab-on-Grade (BRAB) Foundation? These foundations are widely used in Texas, and the WRI (Wire Reinforcement Institute) has a design aid which I am following, but would like to use Ram Concept and would like…

Good Day, I have been experiencing some difficulty as it relates to the design of some shear walls I wish to use for a staircase I am currently modelling in staad. I have attached the staircase model, in which I have utilized plates (to represent the…

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…

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…

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…

I have a two way flat plate. When import from Ram SS, I imported lateral analysis loads too. It created lateral layers i.e. wind, seismic. However, when calculate, there is this "large Stabilizing Reaction Floating Loading" on every lateral layer. Should…

Good Day Everyone, I have completed a staad model of a staircase, however I have been recieving the following error from the shear wall design results "FAILED:NO REBAR IS AVAILABLE FOR VERTICAL REINFORCEMENT". Does any one know why this would occur…

Good day. This is my first time trying RC design on STAAD and I am experiencing some trouble with the beam designs. I am only trying to find out the sufficient reinforcements for my particular load cases but STAAD keeps mentioning that my beams do…

The Concept Manual states under section 53.1.3 that for PT Beams, One-Way Slabs, and Two-Way Slabs ACI 318 18.9.4.2 and 18.9.4.1 is implemented. It is not clear if ACI 318 chapter 12 code provisions are also implemented per 18.9.4.3 since it is not explicitly…

hello. the staad asing the reinforcemen steel with the charge combination most automatic critic? or how can i do to asing the charge combination most critic? since you are giving me the reinforcemen steel in some columns with load 1 and load 1 is…

Good Afternoon I need to know: Which of Bentley's Product do the design of Anchor Bolts according to ACI 318? Best regards, Pablo Mata

Good Day fellow colleagues, I have tested two models to complete a shear wall design using staad pro. In one model I included only the shear walls, beams and columns and in the other model I included all of the above mentions elements plus the slab…

I have RAM Elements 13.4.0.177, which I believe is the latest version. The concrete wall modules, both the concrete wall design and the tilt-up wall design, are still referencing ACI 318-05. Is there or when will there be an update to have ACI 318-11…

I am trying to design my wall with the fixity at ground level pinned, the fixity at foundation level pinned, and the level restraints pinned. These options seem to only be available to me when I choose the simplified analysis method. I get this error…
