Hi, 1) I need to distribute a concentrated load to the beams as Uniformly Distributed Load(UDL) using Yield line theory, which is acting at the centre of slab. Slabs (two way) are not modelled, but the the slab weight is transferred to beam as UDL. 2) If the slabs are not modelled, how to...

Hi, Can anyone tell or give reference to find length of plastic hinge in steel sections for beams and columns? For example in RC sections, it is approximately 0.5 times of depth of the section.

I have modelled concrete with a yield strength of 20 Mpa for a sub-assemblage model. But, from dynamic analysis, the Von mises stress distribution shows a maximum stress of around 60 MPa. What is the reason?

Hello all, I have used concrete damaged plasticity model in concrete. I can see the damage distribution pattern in DAMAGET variable. I want to relate the DAMAGET variable with the tensile stress of concrete? Which stress parameter should I choose only to see the tensile stress of concrete? I...

Hi all, I am assigning Cohesive zone surface interaction parameters as mentioned below in interaction module between bolt and concrete surface. Knn, Kss, Ktt, Normal only, Shear-1 only, Shear-2 only, damage evolution parameter. As far as I searched in the literature, in each paper different...

Hi, In the following figure, I have used spring elements in between the base plates to connect. When I apply gravity load, the results are not converging. But without spring elements, the gravity analysis is converging. I need to include spring elements in the gravity analysis. Can anyone tell...

Hi, To model anchor bolts in ABAQUS, pretensioning force should be specified? The anchor bolts are embedded in the concrete

Hello, I am modelling a single anchor bolt, with base late and rested on concrete. Can anyone guide me how to specify the interaction between i) bolt and concrete ii) base plate and concrete

Hi all, I want to model a single degree of freedom systems with lumped mass (as concentrated force) at the top. I wanted to include the effects of concentrated force in modal analysis (I use Linear perturbation , frequency step)? I could not include the concentrated force in the modal step. Can...

I am doing pushover analysis of a RC frame in ABAQUS. i) Modelling of confined and unconfined concrete in the same cross section (eg. RC column, concrete cover area is considered as unconfined and remaining area is confined) is possible in ABAQUS like in PERFORM 3D or SAP? ii) Also the...

How to apply the scale factor (like PGA scaling, amplitude scaling) for ground motions in Dynamic Implicit Analysis in ABAQUS?

Is it possible to model a stirrup in 2D wire model of an RC frame? I could not able to rotate the stirrup in the required position. Can anyone tell me the solution?. Also how to model centre to centre modelling of beam column of RC frame in ABAQUS?

I have created a 2D wire RC frame in ABAQUS of 3 bays in X direction. No of storey is 5. Column and beam are of rectangular sections. If the number of elements are increased while meshing, the fundamental period is increased. Can anyone tell the reason? Since the stiffness is increased by...

I am doing a dynamic implicit time history analysis of a building in ABAQUS. I have fixed the bottom supports. I am getting this error when running the analysis "ErrNodeBCRedundantDof. How it can be rectified?. Whether the support should be released in the particular direction? Pleas suggest the...

Can anyone suggest a suitable open source finite element software for seismic analysis of concrete and steel structures?

Can we model base plate connection in sap?

Spectral matching or PGA scaling is needed for linear time history analysis also like nonlinear time history analysis?

Anyone has modelled spring element is SAP to get a vertical mode shape in Up and down direction? If yes, How to model those elements?

Can anyone share Peru ground motion (2007)time history, station name :Ica? I am unable to download online

Hello all, I want to model a stick model of a NSE on a slab in SAP 2000. I placed a node on the slab centre and included it to the constraints list at that level. And modelled a column on that node (like in the attached pic). The analysis results shows it is a poorly modelled structure and the...
