“…The fragility curves for unreinforced masonry wall, RC beams/RC columns, and RC beam‐column joint are adopted from the work by Cardone and Perrone, 88 FEMA P58, 68 and Brown and Lowes, 89 respectively. The expected repair cost (

) for considered building components under different damage states is estimated using the repair cost functions proposed in the author's previous work 85 . The general form of the repair cost functions for one unit of building component (in Indian rupees) is expressed as:

R_{E} goodbreak= \sum_{i = 0}^{m} \sum_{j = 0}^{n} \sum_{q = 0}^{p} \sum_{l = 0}^{k} a_{i, j, q, l} x^{i} y^{j} z^{q} w^{l}

“…Structural response of hilly buildings is studied by many researchers under single shock only considering different intensity measures such as PGA, 81 spectral acceleration at fundamental time period [ S a ( T , 5%)], 42,45,82–85 average spectral acceleration between 0.2 and 3 times the fundamental time period [ S a,avg (0.2 T –3 T , 5%)], 46 and spectral displacement [ S di ( T avg , 5%)] 44 . The choice of intensity measure depends on many factors, such as sufficiency, efficiency, seismic hazard, and building design level.…”

“…[42][43][44][45][46] Owing to such irregularity, the vulnerability of hilly buildings is quite high even under single ground motion. In the Indian Himalayan region, where both seismicity and presence of hilly buildings are high, 47,48 it becomes indispensable to study the behavior of infilled hilly buildings under sequence of ground motions.…”

SummaryThe present study investigates the effect of earthquake sequences on the response of reinforced concrete hilly buildings having typical configurations, that is, stepback and split‐foundation, with three different story ratios. A set of 30 as‐recorded mainshock‐aftershock sequence of earthquake ground motions is considered for this study. Mainshock acceleration time histories are scaled at two distinct intensity levels to obtain the mainshock‐damaged building. These mainshock‐damaged hilly buildings are then subjected to aftershocks. A comparative study is performed for various response quantities, such as peak interstory drift ratio, peak floor acceleration, and peak roof displacement of undamaged and mainshock‐damaged buildings under aftershocks. Further, fragility analysis is carried out to study the effect of aftershocks on undamaged and mainshock‐damaged hilly buildings. Subsequently, component‐wise seismic loss estimation due to damage in the non‐structural and structural components is performed. It is concluded from the study that the building components that contribute maximum to the expected repair cost ratio vary with respect to the intensity of the aftershocks. Also, the estimated seismic loss is higher in mainshock‐damaged split‐foundation buildings in comparison to stepback buildings.
