This study examines the inelastic seismic response of low-rise multi-story asymmetric structural system with varying general class of story eccentricities due to bi-directional ground excitation in north-east India. The present study comprehensively analyzes the deportment of stiffness and mass eccentric systems together to perceive the seismic demands in higher modes is found to be potentially high and reflects the real scenario more closely. Study also indicates the degrading attributes of load resisting elements for six-story system may cause increase in inelastic demands owing to ground excitation. This bi-directional component of ground motions is designated for observing the seismic demand of mainly such areas that characterized depends on such layered soil conditions. Inelastic seismic demand may prove convenient in the nomination of the relevant response reduction factor in practical design. This study may help to flourish more insight into the collective behavior of multi-story asymmetric systems, leading to fine tune the provisions in the seismic code.
