ABSTRACT

The capacity diagram is superposed onto the demand diagram in the acceleration-displacement response spectrum format (the ADRS diagram) as shown schematically in Figure 3 to identify the performance point representing the displacement demand on the buildings (δ*eff). The construction of the ADRS diagram has been presented in Wilson and Lam (2006). The displacement demand (δ*eff) is then used to obtain the displacement demand values at each floor level of the buildings (Fig. 4).
