Seismic and Progressive Collapse Retrofit of a Steel Braced Frame Office Building
A case study is presented in this paper dealing with a steel braced frame office building located in Southern Italy and designed for gravity loads only. The building, erected in the early ‘60s, is investigated to assess its behavior with regard to both seismic and progressive collapse performance. At the same time, some possible retrofit strategies are outlined. To this aim, the results of both linear and nonlinear static and dynamic analyses are presented and discussed considering different column removal scenarios. Then, an integrated design procedure involving both robustness and seismic safety is developed using steel-braced frames and mega-truss outriggers. In this context, both seismic and progressive collapse performances after retrofit are investigated.
