In earthquake countries, many types of retrofitting systems for exiting buildings have been developed, but many of them are using heavy and thick members made of concrete or steel used as seismic resisting elements. This paper introduces aluminum braces used to improve the structural performance of medium-high rise RC buildings in terms of both strength and lateral stiffness. The aluminum braces are useful for seismic retrofitting of existing buildings, because it achieves good workability in erection site and reduces the seismic loading and additional loads on the foundations due to their lightweight, and aluminum alloy members owe their long-term corrosion resistance. And in this paper we discuss the connection design and the plastic deformation behaviors of aluminum welded structure, and present a structural fuse concept for aluminum braces that achieve adequate ductile performance.
