| Abstract: | Due to the complex topography, the design and construction of buildings in hilly regions pose unique challenges. The elevation difference between the highest and lowest column base levels can vary greatly, leading to variations in load distribution and seismic performance. This article presents a comprehensive seismic damage assessment of moment-resisting dual-frame buildings located on hilly terrain with a 30° sloping ground, focusing on the influence of shear wall (SW) configurations outlined in the draft IS 1893 for hilly regions. Also, for seismic risk assessment, fragility curves have been developed using incremental dynamic analysis and the seismic irregularity descriptor was evaluated based on the fundamental time period. Three distinct shear wall configurations are considered. Along the slope, all building frames have the same SW configuration in the tallest bay on the downhill side of the two exterior frames, extending the entire building's height. Across the slope, SW has different configurations in the tallest frame on the downhill side from the lowest to the highest column base level—SWA: SW at the centre bay only, SWB: SW at two exterior bays, and SWC: SW at all bays. The differences in column base level lie within the range from 10 to 15 m. Damage indicators obtained from nonlinear static pushover analysis are a foundation for assessing structural performance. The critical damage variables considered include base shear, maximum displacement, spectral displacement, and spectral acceleration, offering a comprehensive understanding of the building's seismic behaviour. The differences in damage values were used to correlate with performance levels of buildings, immediate occupancy (IO), life safety (LS), and collapse prevention (CP), respectively. The results indicated that configuration SWB performs approximately 5–27% better than SWA across various damage indices and approximately 3–6% better than SWC. While it is observed that SWB shows the highest probability of exceedance at OP and IO, the lowest at higher damage thresholds (LS, CP), when the fragility curve and seismic irregularities descriptor are considered. SWB shows superior resilience and structural integrity during seismic events. [ABSTRACT FROM AUTHOR] |
