Seismic retrofit of existing building with soft ground storey: a case study with different strengthening solutions
The current example employs a typical building built in the late 1980s. The building has 5 floors of approximately 180 m2 each, and a soft storey at the ground level. The infills of the upper levels are relatively strong with good quality ceramic bricks and mortar of relatively high strength. The combination of the soft ground storey and strong infill panels in upper floors is the most important characteristic of the building and constitutes a serious structural problem related to its seismic behaviour.
