摘要

•An efficient Bayesian updating method based on Kriging is proposed, i.e. BUS-AK2.•BUS-AK2 adopts two-step adaptive Kriging to perform the BUS analysis.•BUS-AK2 provides a solution to determining the constant c in BUS by Kriging.•The steps of BUS-AK2 for the BUS problem with a small acceptance rate are given.•The proposed method can well deal with the BUS problem with multiple observations.
