Abstract Buildings located on hill slopes are subjected to additional effects under seismic action compared with those flat ground. This article presents Incremental Dynamic Analyses of coupled building‐slope systems incorporating topographic amplification, nonlinear slope movement and irregular structural configuration hill‐side buildings. Two different stable slopes, supporting single multipl...

This study proposes a practical fragility-oriented approach for the seismic retrofit design of case-study structures. relies on mapping increase global displacement-based ratio capacity to life-safety demand ( CDR LS ) building-level fragility reduction. Specifically, due retrofitting is correlated with corresponding shift in median values multiple structure-specific damage states, observing th...

Recent experimental research has shown that ordinary unbounded steel reinforced elastomeric bearings (SREBs) can be considered as an attractive cost-effective option for the seismic isolation of highway bridges. To further investigate its benefits, the current study is focused on the seismic risk assessment of an optimally designed highway bridge isolated by SREB system. A typical three-span hi...

In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures under near fault pulse-like and far fault ordinary ground motions is evaluated through fragility analysis. For this purpose, five sample frames with 3 to 15 stories are designed and imposed to the ground motion excitations with different characteristics. Fragility curves are derived for th...
