Annotation:
There is a representation of seismic performance evaluation method with due regard to economic effect assessment, which consider different seismic retrofit strategies applying for reinforced concrete (RC) soft ground story building with masonry infilled frame in upper stories. The dependencies, which allows to estimate the influence of masonry infill panel, located between structural columns and beams inside the RC frame, on the strength and stiffness, are shown. The analytical model simulation approach, which consider the influence of masonry infill panel on seismic response of the frame, is demonstrated. The analytical dependency, which allows to select the optimal seismic retrofit scheme for this kind of building with due regard to economic consideration, is applied. Two seismic retrofit strategies are analyzed in this study among with non-retrofitted (typical) one, where the first represents the base isolation technique implementation, and the second is the ground story RC columns strengthening by increasing their cross-section and area of reinforcements.
