Seismic Assessment of Vertical Geometric Irregular Building: A Revisit
https://orcid.org/http://orcid.org/0000-0002-4979-0715
Vertical irregular buildings, which are popular, especially in a closely spaced urban locality, are believed to have higher seismic risk. Accordingly, the design codes recommend special design criteria for such building categories. Although a large amount of research effort has been invested in the past, there is no consensus on the seismic performance of vertical geometric irregular (VGI) buildings in comparison with regular buildings. The present study evaluates the seismic safety of benchmark VGI buildings subjected to horizontal and vertical components of earthquake ground motion considering alternate engineering demand parameters. The concrete compressive strain of the column elements is used as an additional demand parameter to capture the building response. The building response is evaluated in terms of seismic fragility curves and response hazard curves using an accepted reliability-based seismic risk assessment methodology. The results of the present study indicate that the inclusion of vertical ground motion components and the choice of demand parameter significantly influence the outcome of the seismic risk assessment.
