Hello,
ACI 318-19, cl. 6.6.3.1.1, provides reduced inertias for different structural elements.
It's clear to me that these values have to be considered for a lateral deflection anlysis, but should they be used as well for obtaining the design forces of those elements in a static (not seismic)...
Good afternoon,
Being an advanced user of SAP2000 I am starting right now with ETABS because of its design capabilities for concrete walls.
I have found plenty of information regarding shear walls, but not so much about basement walls.
As far as I have understood, shear walls design is based...
Hello all,
I have been using SAP2000 Steel Frame Design (SFD) for a bunch of years now but there has always been something going inside my mind about the values of unbraced length ratio (K) calculated by SAP.
Depending in the way you model the frames of a column, the results are quite different...
Hi all,
ACI 318-14, cl.11.7.2.3, says:
"For walls with h greater than 10 in., except basement walls and cantilever retaining walls, distributed reinforcement for each direction shall be placed in two layers parallel with wall faces in accordance with (a) and (b):
(a) One layer consisting of at...
Hello,
I am having some concerns regarding the shear transfer mechanism of anchor bolts.
Let's say I have a (real big) pedestal (1400x5400 mm, f'c=25MPa) supporting a base plate anchored by 27M56 (Fu=410 MPa) and resisting a factored shear Vu=3600 KN (see attached sketch).
Code is ACI-318-14...
Hello,
I am designing a RC beam with a section which, due to architectonical reasons, is much larger than required, resulting in minimum reinforcement both for bending and torsion.
Do I have to calculate both As,min for bending and longitudinal Asl,min for torsion separately and eventually...
I have the following VBA code in a Module within Excel:
Sub Prueba_1(AttachToInstance)
'AttachToInstance = True: usa una instancia de SAP ya abierta (no abre un nuevo SAP)
'AttachToInstance = False: abre una nueva instancia de SAP
Dim ret As Long

Hi everybody,
I would like to know if off-diagonal (aka off-center) bracing systems are allowed in Special Concentrically Braces Frames (SCBF) according to Seismic Provisions of AISC 341-10.
Indeed I haven't found any reference to such type of bracings in the code.
Any clarification or...
Section "6.2.8 Design of column bases with base plates" of Eurocode 3, Part 1-8, shows how to obtain the "Design moment resistance Mj,Rd of column bases" in Table 6.7, but there is something in these formulae I cannot understand:
Mj,Rd is obtained as the minimum value of two formulae (for every...

Hello,
I know how to access a SAP file through the OAPI from VBA, e.g.:
Set ObjetoSap = New SAP2000v16.SapObject
Set ModeloSap = ObjetoSap.SapModel
ObjetoSap.ApplicationStart
ret = ModeloSap.InitializeNewModel
ret = ModeloSap.File.OpenFile(txt_fichero.Text)
Here I...
