Re: UniformExcitation output analysis

Thanks for the reply.
Is this also the same for the acceleration?
So the output is the relative acceleration for a fixed ground bottom and if we want the actual acceleration at the ground surface we need to add the input acceleration at the ground bottom?

UniformExcitation output analysis

Hi everyone, I am performing some transient analysis on a pile foundation recently. I use the "UniformExcitation" to apply the acceleration by fixing the bottom boundary. But, I am confused about the output. The opensees said when using "UniformExcitation", the results are relative value. What does ...

Error when using "recorder mpco"

When I use "recorder mpco" function, this error came out. I think this is because I used the function "clock" in my main tcl file. Does anyone how to solve this problem? ################################################################# couldn't read file "C:/Program Files/STKO/opensees/bin/tcl/lib/t...

How to setup K0 value in gravity step for SANISAND model

Hi I am working on the seismic response of a single pile in sand. The soil model is SANISAND04 proposed by Manzari and Dafalias. There is one problem when I try to simulate the self-weight application step. I want to assign a K0 value equal to 1-sin(phi), phi is soil friction angle. Originally we ca...

Any official example avaliable

Dear developer,

I am a new user of SKTO+opensees.
I see there are some videos on the soil-structure interaction modelling example on the official website.
Wondering if there is any example available that can help me understand the working principle of the software.

Many thanks,
Huan
