A relatively simple probabilistic approach for the seismic performance assessment of building structures combines the SAC-FEMA method, which permits probability assessment in closed form, with the N2 method. In this approach, the most demanding part of the PEER probabilistic framework, i.e. the Incremental Dynamic Analysis (IDA), is replaced by the much simpler Incremental N2 (IN2) analysis. The results of the analyses indicate that the probability of failure of the infilled frames with regularly distributed infill is smaller than that of the bare frame.

A relatively simple approach for the probabilistic seismic performance assessment of plan-asymmetric structures has been proposed. It is based on the PEER probabilistic framework, in which the most demanding part, i.e. the incremental dynamic analysis (IDA), is replaced by the much simpler Incremental N2 (IN2) analysis. Predetermined default values for dispersion measures are needed for the practical implementation of this approach, which can be used for the analysis of plan-asymmetric buildings requiring a 3D structural model.

A non-parametric empirical approach, the CAE method, has been applied for the prediction of the normalized lateral force–drift envelope of reinforced concrete (RC) rectangular columns, as well as their characteristic drifts (effective yield drift, capping drift and ultimate drift), and drift-related parameters (the ratio between the effective yield drift and elastic drift, and two ductility measures). The results suggest that the relations between the input and output parameters are complex, and that it is difficult to isolate the influence of a single parameter.

Simplified inelastic procedures used in seismic design and assessment combine the nonlinear static (pushover) analysis and the response spectrum approach. One of such procedures is the N2 method which has been developed at the University of Ljubljana and implemented into the Eurocode 8 standard. In this study an attempt has been made to predict the target displacement by four-linear idealization of the pushover curve using the approximate SDOF-IDA curves. The application of the proposed methodology is demonstrated using an example of a four-storey reinforced concrete structure.

The error in the prediction of the ultimate drift of the reinforced concrete columns is determined by using the CAE method. The results based on the Kolmogorov-Smirnov test indicated that the error of the predicted ultimate drift in columns is mainly normally or log-normally distributed. For the other cases the typical characteristics of the columns were indicated. Their influence will be reduced with extension of the database.
