    SEISMICLOAD

    Product of ground motion and mass of structure

    Ground acceleration causes both horizontal forcesand vertical forces

    Seismic design coefficients provided by USGS, andformulas given by IBC and ASCE 7 allow simplecalculations that convert ground motion into loads

    Load Used
