Important
It is very important to check accuracy of asva analysis on your own for production use since asva is under development. Please report bugs to Github Issues.
asva¶
asva is a package to simulate vibration response of multi degree of freedom system subjected to earthquakes. Response time history and amplitude can be calculated.
Quick Start¶
Requirements¶
Python 3.8+
Installation¶
pip install asva
