The majority of existing buildings require seismic retrofit. The main reasons are: the original design was not optimized with respect to the required safety level, poor construction quality, modifications or enlargements of buildings during their life and increase in the requirements of seismic design. Even if steel solutions can often be more efficient and economic, their possibilities are practically unknown and their application has been limited to a few particular cases. The aim of the research proposal is to set up steel solutions for the seismic retrofit of existing buildings, providing design and construction methodologies, tools for dimensioning of elements and connections as well as for cost estimation.
