Hi,
Can anyone help me on how to come up with a factor that is used when calculating seismic load?
Is the factor 0.75 is related to selfweight and second-order analysis?
Example is:
LOAD 1 ( SEISMIC LOAD IN X DIRECTION )
UBC LOAD X 0.75
LOAD 2 ( SEISMIC LOAD IN Z DIRECTION )
UBC LOAD Z 0.75
This is example from STAAD 5.31.2.1
Thank you for the help?
