Study Notes

There are 17,000 RC buildings built before 1980 in high seismicity regions in California.
Efficient screening methods are needed to identify the most vulnerable structures.
This study focused on low- to mid-rise RC frames without shear walls.
Six seismic vulnerability indicators (SVI) and nonlinear dynamic analysis (NDA) were studied.
The SVIs include column index, ratio of moment capacities, ratio of column shear capacity, axial load ratio, ratio of building initial fundamental period, and ratio of building base-shear demand.
The methods were evaluated using numerical analysis and observations from 18 cases in Turkey and Nepal.
Column index produced the best correlation between observed frequency of damage and estimated vulnerability.
Buildings with lower column index have higher frequency of severe damage.
Retrofit work should start in the buildings with lowest column index.
Column index requires the least amount of information and computational effort.
