I need Clarification about the difference of the results observed in these two models ,i have attached my two models
1.The first model i created Steel columns ,and below steel column i created a concrete column as observed on attached model ,the design results of these concrete columns are as shown on the attachment
3716.Structure1.STD
Structure1-Column-1.zip
2.The second model i created Steel columns ,and below steel column i didn't put concrete column,i designed my pedestal in RCDC ,the design results of these pedestals are as shown on the attachment
Hello Abhisek M may you help me about this scenario
Hi,
Request you to also share both the RCDC files.
check on the post ,i attached the Staad file together with RCDC file, for both cases.
It seems that both the files that are attached are same. request you to re-check and upload the staad file and RCDC file with Concrete pedestals modelled.
1.Model with concrete column
Structure1 with column.STD
Structure1-Column-1 with column.zip
2.Model without concrete column
Structure1 without column.STD
Structure1-Column-1.R6without column.zip
Case 1 – Concrete Pedestal modelled below Steel column in STAAD vs
Case 2 - Concrete Pedestal is designed in RCDC.
In case 1, the forces transferred from Steel column to concrete pedestal is higher than that compared to Case 2 where RCDC reads the Beam end force of steel column and transfers it to RCC Pedestal that is created in RCDC.
How RCDC works for case 1 –
As the concrete pedestal is already modeled in the STAAD model and imported, RCDC reads the Top and Bottom force of each RCC Column or Pedestal and designs it as a Column as per the forces fetched from STAAD model.
How RCDC works for case 2 –
So, in both the cases that you are trying to compare above,
If Column Forces at Top location will be same in both the cases and also if the Pedestal size is same, then you will be able to get appx. same results for both cases in RCDC.
Then what i was asking is that,they all have same loading with same member sizes why do they give different results
