Fragility curves for steel-concrete composite shear wall RCC infill moment resisting frame system

Abstract

This paper aims to illustrate the influence of Brick Masonry Infill (BMI) in reinforced concrete (RCC) buildingcomposite shear walls dual system using the capacity spectrum method. The capacity spectrum method captures the unpredictability and ambiguity related to capacity spectrum properties, damage states, and characteristics of ground motion. Spectral displacement-based fragility curves and damage probability matrices subjected to different damage states are generated for the bare frame, frame with only BMI and frame-steel concrete composite shear walls (SCCMSWs) system with BMI. From the comparative study of the damage probability matrices, it is concluded that frames with BMI and SCCMSWs have shown better performance during the action of the lateral load.
