 After we completed a detailed seismic assessment of this 10 storey plus penthouse, 1929, riveted steel building we were engage to design strengthening schemes to target 50, 80 and 100%NBS.  The schemes involved a new couple concrete shear wall core across the building and new sprayed concrete shear walls at the side walls along the building.  The strengthening scheme gained new floor area for the building by incorporating converting existing light wells into floor area as part of the strengthening schemes.  Significant foundation works were required in the basement area and the floor structures required strengthening to achieve the required diaphragm capacity.
