DESIGNLOADS
Composed of:
Dead Loads:
loads that are relatively constant overtime
for example: floor tiles, carpet, walls
Live Loads:
short, temporary, or moving loads
for example: people, desks, chairs

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
