Spectral Acceleration as an Efficient Seismic Damage Measure for Bare and Masonry Infilled R/C Frames

ABSTRACT

The paper investigates the potential of adopting the spectral acceleration S_a(T) as an efficient measure for the estimation of the seismic performance of bare and infilled R/C buildings within the context of Performance-Based Earthquake Engineering. A large number of planar R/C buildings with different masonry infills’ distributions are analyzed using nonlinear time-history analyses. The correlation between several damage measures and the S_a(T) for a wide range of periods is investigated. The results point out the conditions under which the S_a(T) can be used as an efficient parameter that describes adequately the damage response of bare and infilled R/C frames.
