Hello everyone,

Has anybody used the iso2spring in Opensees ? I want to calculate the periods of my structure and i read that i have to do firstly a static analysis. I have done it and the vertical period is correct but i apply only a vertical load. How is the first period (horizontal) is calcultated ? ( I have a simple model of two nodes )

Thanks in advance
