- An analytical investigation of the performance of reinforced concrete buildings designed primarily for gravity loads is presented. In first part, the seismic performance of nonductile reinforced concrete frame buildings in regions of low to moderate seismicity is evaluated. Several significant aspects of non-ductile detailing are modeled using rational simplifications of expected member behavior at critical sections. The detailing configurations included in the analysis are: (1) discontinuous positive flexural reinforcement; (2) lack of joint shear reinforcement; and (3) inadequate transverse reinforcement for core confinement. Inelastic time history analyses are carried out under moderate to severe earthquake excitations.
