The GIB system consists of a pinned brace and a gap element that is installed almost vertically at both sides of first story columns in existing buildings prone to a soft-story response. This intervention promotes the isolating benefits of the soft-story at the ground level to protect the upper floors of the structure from damage while greatly increasing the lateral deformation capacity of the first story and eliminating its propensity for collapse. An overview of the system and its potential benefits to soft-story buildings is presented and a summary of the main steps of a design procedure for retrofitting soft-story buildings with this system is provided. The potential impact of the GIB system is then examined through a cost benefit study. The seismic response, the retrofit cost and the seismic repair cost of a six-story reinforced concrete (RC) frame retrofitted building using conventional approaches such as strengthening and stiffening of the soft-story is established and compared to the un-retrofitted existing building and the building retrofitted using the proposed GIB system. Subsequently, selected results from an ongoing full-scale testing program carried out at the University of Toronto to confirm the behavior of the GIB system are summarized.
