Abstract: This project was a single-span frame structure, with a poor seismic behaviour and needed to be retrofitted. Considering its architectural appearance and using functions, frame columns were decided to be added, for changing it to be a multi-span frame structure. And according to the results of the following seismic checking and Pushover analysis, the reinforcement scheme was proved to promote the structural system and seismic performance effectively. Meanwhile, this paper may also provide some references for related designs in the future.
Keywords: single-span frame structure; retrofitting; seismic analysis; Pushover
