    Yield line theory for concentrated load and modelling

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

    Yield line theory for concentrated load and modelling

    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...

    Length of Plastic Hinge in steel sections

    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.

    Regarding CDP model

    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?

    Regarding DAMAGET variable

    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.

    Regarding DAMAGET variable

    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...

    Cohesive interaction zone parameters

    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...

    Regarding Gravity load

    Do you know how to apply forced displacement on ABAQUS?

    Regarding Gravity load

    Yeah did that. Then also it is not converging

    Regarding Gravity load

    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...

    Pretensioning anchor bolts

    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 .

    Pretensioning anchor bolts

    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?

    Pretensioning anchor bolts

    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...

    Pretensioning anchor bolts

    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...

    Pretensioning anchor bolts

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