A single-record IDA cannot fully capture the behavior that a building may display in a future earthquake event. Therefore, the multi-record IDA is developed to consider the record-to-record variations in earthquake ground motions. However, neither single-record IDA nor multi-record IDA can take into account the random system properties of structures. In this paper, a stochastic IDA method is proposed, which is a coupling of point estimation method (PEM) based on Nataf transformation for approximating the statistical moments of random functions, and single-record IDA approach. The multi-variable random IDA curve is developed from single-variable random IDA ones according to the sampling strategy in PEM, and the fractile IDA curves are also advanced. The proposed methodology is applied in R.C. frame structures. A three-bay and five-storey plane R.C. frame is taken as an example in case study. It is demonstrated by this example that the approach proposed in this paper is an efficient and accurate tool for probabilistic seismic demand and capacity analysis of structures considering the inherent random system properties.
