Turkey has frequently suffered major damaging earthquakes in this century. Still, there are thousands of apartment buildings in earthquake-prone regions in Turkey that need the evaluation and seismic rehabilitation. So that, the seismic capacity of an existing RC school building at Turkey have been evaluated according to the 1st and 2nd screening level as it is represented at Japanese guidelines for seismic retrofitting of existing RC buildings, 2001. Once the seismic capacity of the building is evaluated and it was found that the seismic indexes are within 0.19 – 0.77, a simple seismic strengthening method of a new brace system using concrete filled tube and fiber reinforced concrete is analysed as a retrofitting scheme. Either of these braces is a single line element and easily placed in a frame.
