PART 4 Seismic Definition in STAAD

[@hyunwun3098]

Sir why is GY has been removed?and what if id input a negative load on the seismic definition.will i encounter an error?

[@cereference4438]

Gy is removed when defining seismic load. Remember, we are only defining seismic load to determine base shear which is not sign dependent since STAAD will distribute that vertically and horizontally. Check my other videos verifying vertical distribution of earthquake in staad
