Does STAAD design for CONCRETE SPECIAL MOMENT FRAME as per ACI 318M-11 ??

Sanjay Kumar — Wed, 10 Jan 2018 04:50:00 GMT

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 concrete design ??

2. Incase, its not available in the batch mode !!! Is the above ductile detailing provision addressed in the RC designer module ?

Regards,

Sanjay

P delta analysis , Pdelta kg effect

Sanjay Kumar — Thu, 08 Oct 2015 06:25:54 GMT

hi,

I have two questions..

1. While running PDELTA analysis in STAAD, how to include the effects of a service level dead load e.g. DL+ 0.25LL, before starting the PDELTA analysis for my repeat load combinations..

load case 1 DL

load case 2 LL

load case 3 EQ

load case 4 DL+0.25LL (service vertical load) ( the result of this load case shall be linear)

load case 5 EQ ( P delta analysis for this particular load case alone, which includes the linear analysis results of load case 4 )

load case 6 DL+0.25LL +EQ ( using REPEAT LOADS for this combination isnt the same as the results of load cases 4 and 5, which were run sequentially )

Can someone clarify me, on how to apply service level vertical loads and using it as reference, before running Pdelta analysis for lateral load cases !!!

2. What does the PDELTA KG command do actually ? can someone share me a link, to understand the "stress stiffening effect which is said to be accounted in stiffness matrix" !!!

openstaad .. syntax problem

Am not able to get the node distance of between two nodes .. am a basic level programmer.. pls clarify if I have made a mistake here

Public Sub node()

Dim NodeDistance As Long
Dim NodeNoA As Long
Dim NodeNoB As Long

Set objOpenSTAAD = GetObject(, "StaadPro.OpenSTAAD")

NodeNoA = 498
NodeNoB = 665

objOpenSTAAD.Geometry.GetNodeDistance NodeNoA, NodeNoB

Cells(1, 8) = NodeDistance

End Sub
