Existing reinforced concrete buildings in the Mediterranean area are vulnerable to seismic actions due to the lack of proper seismic detailing. Different retrofit solutions are available on the market and effective in improving the seismic performances. However only few of them can be easily applied in-field with a reduced impact for the occupants. In this context, fiber-reinforced polymers gained popularity because of their demonstrated effectiveness, ease of installation, reduced total cost and durability. This had a significant impact on the current market of retrofitting worldwide with increasing number of applications of FRP strengthening. In this context this research work proposes a novel software tool to drive practitioners through the computer aided design of FRP strengthening for existing beam-column joints. It relies on the design approach suggested in the fib bulletin 90 including recent development in terms of novel techniques to minimize the impact to the occupants. Local strengthening or global seismic retrofitting can be used and the increasing seismic performance can be easily quantified.

Abstract
Existing reinforced concrete buildings in the Mediterranean area are vulnerable to seismic actions due to the lack of proper seismic detailing. Different retrofit solutions are available on the market and effective in improving the seismic performances. However only few of them can be easily applied in-field with a reduced impact for the occupants. In this context, fiber-reinforced polymers gained popularity because of their demonstrated effectiveness, ease of installation, reduced total cost and durability. This had a significant impact on the current market of retrofitting worldwide with increasing number of applications of FRP strengthening. In this context this research work proposes a novel software tool to drive practitioners through the computer aided design of FRP strengthening for existing beam-column joints. It relies on the design approach suggested in the fib bulletin 90 including recent development in terms of novel techniques to minimize the impact to the occupants. Local strengthening or global seismic retrofitting can be used and the increasing seismic performance can be easily quantified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
