Abstract:

Seismic fragility was assessed for RC frame-shear wall structures designed according to current Chinese seismic design code for buildings, taking into account the uncertainty of earthquake ground motions. The site soil type and the seismic protection intensity were considered to be the main design variables of the reference structures. Fragility curves for four performance levels, i.e., fully operational, operational, repairable, and collapse prevention, were developed in this study. The plastic rotation at the ends of structural components (or the total chord rotation) and the inter-story drift ratio, which reflect the damage state of the structure from the viewpoint of the structural component level and the story level respectively, were employed as performance indexes. The results indicate that the seismic performance objectives of RC frame-shear wall structures designed according to current Chinese seismic design code can be achieved with good reliability.
