The purpose of SDOF system is to simulate a machine. And to study its behaviour under dynamic analysis. I am doing in SAP 2000

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?

Thank you

Thank you, Hello, one more doubt.. for cyclic loading we should check PEEQ or PEMAG? what is the difference? I can see PEEQ has higher strain than PEMAG.

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...

These papers discuss about the steel concrete interface

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...

The error got resolved. Thank you

Do you know how to apply forced displacement on ABAQUS?

Yeah did that. Then also it is not converging

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 dold, 0.8Fy as suggested from literatures. I am simulating a shake table testing experiment in ABAQUS model and validating it. So it is necessary .

Thank you, I am validating ABAQUS model with experimental results. So the dimensions are already fixed. for i) , iii) and iv) Can you suggest any standard reference books?

Hi, This is a cooling tower model which will be located on roof top of a building. Sub assemblage modelling of connections I am doing in ABAQUS. Spring elements are attached between two base plates to reduce the vibration effects to buildings. Post installed expansion anchor bolts (HSL 3G, M16...

No, intent is simulating a anchor bolts in ABAQUS. The anchor bolts are attached to the foundation of a machine. The nut is present on one side only. The other side is inside the foundation. In that case, is it necessary to consider the pretension? . Pretension will be generally considered for a...

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

Hi, Yes I have used as suggested by you. But, the error is repetitive always "WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE BOLT_24SW-1.262 D.O.F. 2 RATIO = 32.1574E+12 . ***WARNING: DISPLACEMENT INCREMENT FOR CONTACT IS TOO BIG. ***WARNING...

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
