| Summary, etc. | The present study is an effort to investigate the reason of severe seismic vulnerability of structures with plan irregularity. Such structures are found very commonly all over the world. This study initially aims to model the structures in standard finite analysis based software maintaining their accurate geometrical shape find out natural mode shapes and natural lateral periods of such systems. Closeness between higher and lower lateral periods indicate the reasonable possibilities of influence of higher modes in overall seismic response. The higher modes are seen to have concentrated deformations at some critical locations. To understand the implication of this observation, further, a response spectrum based CQC (complete quadratic combination) analyses are carried out. Outcome exhibits that the similar critical locations are over stressed. The early yielding in these locations may result in load transfer to other members subsequently. Such cascading effect is predicted as the possible reason of increased vulnerabilities of such structures. Relatively, more strengthening of such members in critical zones may help to alleviate these problems. Alternatively, the building may be structurally divided into rectangular blocks so that they can undergo independent vibration eliminating the possibility of stress concentration. Further, detailed study encompassing many possible irregular plan building is the need of the hour for formation of design provisions. |
