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

Wind Loads Earthquake / Seismic Loads

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

- 36 kip (horizontal)

Ev - 18 kip (vertical)
