A Review on Seismic Performance of L-Shaped Building Through Plan Irregularities

The patterns of sporadic structure development have quickly expanded because of tasteful and restricted accessibility of land. Past examinations have indicated that the structures with design abnormality are harmed under solid ground movement. Auxiliary inconsistencies are significant elements which decline the seismic exhibition of the structures. Structures having basic anomalies bring about the lopsided circulation of the story float, exorbitant twist, etc. The irregularity discussed here are about plan irregularity which is available in re-participant corners and torsional anomaly which is caused by abrupt changes in firmness and twist enhancement factor in building. This study is to propose a feasible solution to build this kind of structure in seismically active areas using analytical methods with the assistance of ETABS software. The analysis shall be done through a comparable static horizontal power technique and reaction range examination (dynamic investigation). The basic reactions will estimated regarding story displacement, inter-story drift ratio, torsional irregularity ratio, torsional diaphragm rotation, normalized base shear force, and overturning moment, which are also called seismic response demands. The structure will be analyzed and compare with different types of other shape plan.
