Correlation of Inelastic Analysis and Destructive Tests on a Reinforced Concrete Building

M. R. Button / R. Donikian / E. Crespo

Results are presented of a study of the dynamic response of a non-seismically designed, eleven-story reinforced concrete building. The analytical response was determined with the use of a linear elastic computer analysis program, and was correlated with its measured response from small amplitude, non-destructive, mechanically induced shaking. The influence of the stairwell, infill panels and foundation flexibility on the dynamic characteristics of the structure was included in the analysis. The predicted analytical inelastic response of the structure was correlated with the inelastic response measured from mechanically induced, large amplitude shaking tests which induced maximum roof displacements and caused severe structural damage. In addition, the best fit nonlinear model of the structure was used to predict the response of the structure when subjected to earthquake-induced ground motions. It was concluded that in areas of high seismic risk, the structure would represent a significant safety problem. In areas of low seismic risk, the structure would retain its structural integrity and remain functional after an earthquake.
