I tried to Design a Staircase using Multiple Imposed Loading method under slab design in RCDC, there is no option for Live load Input in it and In Design Calculation also I Could not see Live load Included in Calculation.

In Staircase design, why RCDC is not considering any Load combination in Design and where to add the dead load of steps over waist slab? and Which Panel type to be adopted in staircase design?

i have a doubt in STAAD RCDC Connect Edition (Advanced Concrete Design) version 11.06.00.56, please correct me if my understanding is wrong. based on the thickness we define (say 200mm in the below snap), the program computes the selfweight and adds…

STAAD version 22.08.00.175, RCDC 11.01.00.18. I have modelled a building in STAAD. I was able to design beams , columns , footings using RCDC. But when I import the STAAD file for designing slab, I am getting a error: Error in Model. Cannot detect slabs…

How can i design a this kind of slab on staad pro, i'm still a new user of the software so please put some detail to help me.

Hi All, I am designing an elevated concrete podium slab which will carry 4 floors of timber above. The perimeter of the slab is supported by 4 basement walls and the distance between columns is about 24ft top to bottom and 18ft left to right. I attached…

Hi, I have been trying to validate my RC slab design as per IS 456:2000 using RCDC software. While checking i found following issues in RCDC:- Design moment & shear are on higher side - As per IS 456:2000, effective span of slab (calculated as…

In a project I'm working on the resulting SSR designs seem a bit extreme and in odd places. The system is a Two-Way flat plate slab, with some edge beams to support precast panels. There are four columns that have had SSRs placed within the beams framing…

Concept is providing a "Performance" warning upon running analysis, stating that there are "Too many user bars to detail". The strips are 320' long and are supposed to have #5@14" perpendicular to the 320' length (about 275 bars). Does this warning just…

The definition in the manual for the Cover to CGS is "the distance from the top of the slab to the bottom of the top bar". This will be the bottom of TOP bar or TOPTOP bar? What I've found is that, this value greatly affects the result of punching shear…

Hello, I am new to STAAD and this forum, and this is my first post! I wanted to model an 8.67' X 31.5’ Slab with a 16,000 lb. load applied at the center. The slab will have fixed ends at all sides. As a “one-way slab”, the expected max moment utilizing…

Hi, I've come across this particular issue a number of times but have never had RAM specify this much shear reinforcement before - see snapshots below. This is a one-way slab and band beam system so wouldn't be expecting shear ties in the beam like…

I put load on my floor using partial plate load. Will RCDC include the load from the plate? If not, what are my other options to calculate ny slab. please help.

Hi, In designing RCC slabs conforming to BS 8110 we check the deflection only along the shorter span of the slab only. But in RCDC reinforcement area increased in along long span also considering the deflection of the slab. What is the reason for that…

Hello, I am working on a school project, so I am not experienced, just to be clear. But I have a slab openings on my floors for stairwells and elevators in the RAM modeler. However, my understanding is that RAM won't apply floor loads where there…

Hi, I am just wondering how to model soft spot on RAM Concept. I have treated them as an opening, however, when we have walls below it doesn't work because the wall won't be attached to the slab. Any ideas? Many thanks, Leticia

I have been model the plate ,base on same thickness same load, but different mesh size as show on the picture. The result of bending moment are differ (shown on picture). I want to get bending moment value to design reinforcement rebar, but i am not sure…

Hello everyone, I am working for one of the underground metro projects where I have to design various slabs. These slabs have to be designed for bending moment, torsion and shear force for large number of load combinations. The practice which I am following…

Hello STAAD.Pro experts! I am in the middle of a slab design using STAAD.Pro v8i. The model is ready and i am starting to use the STAAD.Pro RC designer. I want to design the slab according EC 2, but when I choose the standard EC 2:1991 or EC 2:2004…

Hello I'm just a beginner in staad pro. I'm trying to design a 6-storey building. After analyzing the structure i used commands option to perform concrete design. It gave me reinforcing details for column and beam. But not for slab. I added plates for…

Can you please explain how to interpret the element design of the attached files with two different result which is in accordance to the 2008 ACI code. Advice us what area of reinforcement should be use in each case for steel at the top of slab and bottom…
