“…However, structures designed by force-based design methods, such as the method of EC8 (2004), do not have a specific target IDR. For such a case, one can estimate the ID R max according to the hybrid force/displacement (HFD) seismic design method (Pian et al, 2020a, 2020b), which is a PBSD method providing comprehensive empirical expressions to predict the performance metrics for various types of RC structures. For reasons of completeness, Table 6 summarizes all these expressions related to the HFD method for RC structures.…”

“…However, it has been shown that the equal displacement rule may overestimate or underestimate deformations (Pian et al, 2020a, 2020b). Thus, a better alternative to estimate the IDR is the HFD method proposed by Pian et al (2020a, 2020b) for the PBSD of RC structures. The HFD method is summarized in Table 6 where a series of equations are given for each of the three types of RC structures considered here.…”

This study introduces a simple and efficient method to determine the peak floor acceleration (PFA) at different performance levels for three types of plane reinforced concrete (RC) structures: moment-resisting frames (MRFs), infilled–moment-resisting frames (I-MRFs), and wall-frame dual systems (WFDSs). By associating the structural maximum PFA response with the deformation response, the acceleration-sensitive nonstructural components, and the building contents, can be designed to adhere to the performance-based seismic design of the supporting structure. Thus, the proposed method can accompany displacement-based seismic design methods to design acceleration-sensitive nonstructural elements to comply with the deformation target of the supporting structure. The PFA response shape is represented by line segments defined by key points corresponding to certain floor levels. These key points are defined by explicit empirical expressions developed herein. The maximum PFA response is correlated with the maximum interstory drift ratio (IDR) and other vital characteristics of the supporting structure such as the fundamental period. The proposed expressions are established based on extensive nonlinear dynamic analyses of 19 MRFs, 19 WFDSs, and 19 I-MRFs under 100 far-fault ground motions scaled to capture different deformation targets. Realistic examples demonstrate the efficiency of the proposed method to assess the PFA response at a given IDR, making the method suitable in the framework of performance-based design.
