Re: RC Ring Beam

Following on from 2) do you think it would be reasonable to modify the rigidity of the diaphragm/ links by changing the penalty function setting?

Re: RC Ring Beam

Thanks for getting back to me, just a few further questions,

1) Is there an example model available where a RC ring beam has been utilised? Just so I can see how they have been connected.

2) I have tried to copy the examples provided by applying rigid diaphragms and rigid link between all roof ...

RC Ring Beam

Hi,

I am trying to analyse the benefit of an RC ring beam on a single storey masonry building using a static pushover analysis. I have created both models separately but I am getting a better performance on the model without the ring beam which goes against what I was expecting. Is there a common ...

Unknown Error for a simple Infill masonry Eigenvalue Analysis

Hi,
I have tried to create a model utilising infill panels within a RC frame but when i am running an Eigenvalue analysis i am getting an "Unknown Error" with all the outputs stating either an "Imaginary or null eigen-solution".

Is this common and is there something I would have done wrong for ...

Re: Static Pushover Analysis on a one story masonry building

Hi,

Thank you for getting back to me, I have been comparing my model with the example model and I notice that the Target Displacement cannot go above 0.01 without the simulation failing to complete. This is what's happening for my model also (i.e. at Target Displacement of 0.01 my model runs fine ...

Static Pushover Analysis on a one story masonry building

Hi,
I'm having difficulty with undertaking a static pushover analysis on a one story masonry building. I'm getting the error suggesting that the structure fails for all loadings I apply, even when I wouldn't expect it to. I have changed the convergence criteria and tried to follow the guidance ...

Masonry Walls mid point appearing at node instead of base

Hi,
I am new to seismostruct and I am trying to model a simple one storey masonry building with space allowing for windows and doors. I have managed to add the required material, sections, element classes and placed my nodes by following various video tutorials and this seems to have worked but when ...
