For the sake of testing, I tried using the building wizard to quickly create steel and concrete structures with 7 bays, 5 storeys (3m each), and 4 frames. The reinforced concrete structure had a first mode period of 0.522 secs, while the equivalent steel structure had a period of 1.722 secs. What ...

Greetings!

I recently noticed that the building period of steel structures in Seismostruct is unusually large. In our manual computations, we expected a period of around 0.6 secs for a 5-story building. However, the software gave us a value of more than 2 secs. Is there a fix for this?

Thank you.

Dear z.gronti,

How do I get the peak ground acceleration (PGA) value corresponding to the drift value? Is this done by using the scaling factors (ex: 0.5 scaling factor = 0.5 PGA)? Does this mean that I need to get the drift values every scaling iteration?

Thank you!

Greetings!

I am performing incremental dynamic analysis (IDA) in order to obtain the fragility curve of my structure. I intend to plot the peak ground acceleration (Y-axis) vs Drift (X-axis). Is there any way to do this in the software?

Thank you!

We are trying to use the "Code-Based Checks" function of Seismostruct for our 5-story residential building made with steel beams and columns. In the "Frame Elements" tab, no elements are showing. Is there any way to make the "Code-based Checks" function work on steel structures?

Thank ...

Dear Z.gronti,

I have a few follow-up questions:

1. Is there a way to set the self-weight of slabs outside the building modeller facility? From what I know so far, slabs are modelled as rigid diaphragms in this software. However, I can't seem to find where I can change the self-weight properties ...

Thank you for the response!

Hello, new user here!

I am trying to perform a static pushover analysis on a 5-story building with steel columns (W-sections). Does the building modeller have this functionality?

Follow-up question, does Seismostruc automatically calculate the self-weight of the elements present in the building ...
