Story Shear-Total unfactored(strength-level)shear force induced at level x,=Fx in ASCE 7 equation 12.8-11. Diaphragm Force-Minimum ASD-factored force for diaphragm design,used by Shearwalls only for drag strut forces,as per Exception to 12.10.2.1.Fpx is from Eqns. 12.10-1,-2,and-3.Design=The greater of the story shear and Fpx+transfer forces from discontinuous shearlines,factored by overstrength (omega)as per 12.10.1.1.Omega=3.0 as per 12.2-1. On at least one level and force direction,a torsional irregularity was detected and torsional amplification factor Ax applied according to 12.8.4.3.Refer to the Torsional Analysis section of the Log File output for the values of Ax. Redundancy Factor p(rho): E-W 1.30, N-S 1.30 Input by user(overriding calculated value). Applies to shearwall design,hold-down forces and the drag strut force component based on shearline forces;does not apply to story drift,out-of-plane force, or the diaphragm force Fpx and the drag strut force component based on it. Vertical Earthquake Load Ev Ev=0.2 Sds D;Sds=1.08;Ev=0.216 D unfactored;0.151 D factored;total dead load factor:0.6-0.151 =0.449 tension,1.0+0.151=1.151 compression. • 31 Page 56 of 63
