Abstract

This study presents the fragility curves of regular and irregular moment-resisting frames using different heights, materials, and ground motion records. The concrete and steel frames used in this study differed in terms of height, namely, 3, 6, and 9 stories. Each type of frame was designed based on Eurocode 2 and Eurocode 3 with the aid of Eurocode 8 for earthquake loading. Incremental dynamic analysis (IDA) was conducted for the three selected ground motion records using SAP2000 software as the main tool. The IDA curves were compared to the five levels of the limit state of FEMA 356: operational phase (OP), immediate occupancy, damage control, life safety, and collapse prevention (CP). Based on the analysis of fragility curves, irregular frames exhibited a higher probability of reaching OP and CP levels compared with regular frames.
