Hi All,

I'm using Seismosignal to get the displacement and velocity response of an acceleration time series from testing. However, the displacement and velocity responses do not seem right. Any suggestion what might be possibly wrong ? See the link for the snapshot of all the time series below ...

Hi Seismosoft team,

Yes, I did see the help section. The explanation of Bo and B1 in the help section is the same as in the manual.

By saying that it has an error, do you mean that there is an error in the formulation/coding of the takeda model (error in Bo and B1 parameters) in Seismostruct or ...

Hi Tim,

Thanks for your suggestion. I'm wondering if a model with rigid offsets can be used with the lumped plasticity approach. A model with rigid offsets would include beams and columns with center-line dimensions and connected at one node at a joint. We can then account for the joint panel ...

Hi All,

In Seismostruct, the two parameters for stiffness degradation in the Takeda model are outer and inner loop stiffness degradation (both for unloading stiffness ?). Standard literature, like the book Displacement-Based Seismic Design of Structures refers to controlling parameters of alpha and ...

Hi All,

I've modeled a lumped plasticity model of an RC frame. It is designed to capacity design principles and the joint flexibility can be ignored.
My objective is to get the floor acceleration response histories and not a detailed assessment of the structure itself.

Do you have any ...

Hi Tim,

Thanks for the detailed response and guidance.

The Rise-Hold-Decay is used to simulate the non-stationary nature of an earthquake event. The standard accepts a linear approximation of the envelope. I'll look into the differences that result from the three options in SeismoArtif. The ...

Hi everyone,

I want to generate artificial floor acceleration response histories for shake table testing of non-structural elements. My target response spectrum is from ICC- AC -156, which establishes acceptance criteria for seismic qualification testing of NSEs.

1. The ICC 156 requires a build ...

Hi Seismosoft team,

What are the current limitations of Seismosignal with an academic license?

Best regards,

Hi Seismosoft team,

Is there any plan to release some verification examples for the Pinched Asymmetric Curve to demonstrate its capabilities for various pinched and degrading behaviors ?

Best regards,
Rashid

Thank you Seismosoft team. This will be a great addition. When will the 2019 version be available ?
