Seismic Fragility Estimates Through Time History Method and Re-entrant Corner Buildings with Soil Structure Interaction

Ramesh, B. M. / Manjunatha, K. / Naveenkumar, D. T.

The subject of this study is reentrant corner irregularity. Through the use of nonlinear time history analysis, this study compares a building with re-entrant corners to a structure with a regular plan configuration. Five alternative models examined in the current study are regular (R) building with a square-shaped plan, and four irregular structures, each having a C, L, T, and + shaped plan. Nonlinear dynamic (time history) analysis has been performed on the models for three earthquake data of varying magnitude and pseudo spectral acceleration is compared. Further, fragility curves were also developed to study the variation in the performance levels of all the models for different support conditions (fixed support, hard soil, medium soil, soft soil). Re-entrant corner structures experience greater displacement and more susceptible to seismic damage when compared with regular buildings.
