The inelastic response of reinforced concrete multistory frames was investigated by subjecting small-scale one-bay three-story reinforced concrete frames to a series of strong base motions simulating one horizontal component of representative earthquake acceleration records. The test results were evaluated from the perspective of analytical methods routinely and economically available to structural-design office: linear dynamic response analysis and static limit analysis based on elasto-plastic response. Linear dynamic analyses provided a good qualitative understanding of the observed inelastic behavior. The observed maximum base shears and overturning moments were much higher than the values predicted by the limit analysis due to strain-hardening of the steel. It is concluded that strain-hardening characteristics of the reinforcing steel must be explicitly considered in the earthquake-resistant design of reinforced concrete structures, especially in relation to design of web reinforcement, foundations, and columns.
