Abstract :
A procedure for updating the Park-Ang damage index of reinforced concrete
building under near-fault ground motion is proposed. Rather than developing a new damage
model, a correction term is added to the existing damage model within the Bayesian
framework. The correction term is described as a linear function of the variation of sti ness
of structures, which is a more consistent indicator of predicting the level of damage. The
Bayesian method is an e ective approach when new data become available. The reinforced
concrete building damage data during past near-fault pulse-like earthquakes were used
in updating the damage model. The proposed damage index is conceptually simple and
realistic.
