Simplified Static Force Procedure

[Subject Prev][Subject Next][Thread Prev][Thread Next]
When using the Simplified Static Force Procedure and developing diaphragm
forces, the 1997 UBC states that the diaphragm forces should be within the
bounds of (0.5)*Ca*Wpx and (1.0)*Ca*Wpx.  Should these upper and lower
bounds of diaphragm force be divided by 1.4 when using ASD (Allowable Stress
Design) as you would for the base shear equations?  Thank you.
