6-A4 Building Capacity
Building-specific capacity properties of interest include the yield capacity control point (Dy, Ay) and the ultimate capacity control point (Du, Au), as calculated by Equations (A6-2 through A6-5, respectively):
Cs = seismic design coefficient — values of Cs are given in Tables A6-2a and A6-2b, respectively,
α1 = modal weight factor, Alpha 1 — values of α1 are given in Table A6-4,
Te = elastic period, in seconds — values of Te are given in Table A6-3,
γ = yield strength factor, Gamma — values of γ are given in Table A6-5,
λ = "overstrength" factor, Lambda — values of λ are given in Table A6-5, and
μ = "ductility" factor, Mu — values of μ are given in Table A6-6.
