For the past decades, engineers all over the world are having a rapid progress
for enhancing and reinforcing the existing structure all over the world and the
technique is called retrofitting. In Indonesia, many structures are designed with
the old code and even without the earthquake detailing design. This might cause
a huge damage impact and loss for a crowded structure in low occupancies
building such as restaurant. Seismic assessment is conducted to prevent the
seismic hazard in the future.
This research is conducted to study about the applied retrofitting to an
existing building and analyzed using the non-linear analysis method provided by
a software. In this paper, the role of column damage and collapse in the seismic
response assessment of existing reinforced concrete buildings are monitored and
retrofitted using the methods of RC Jacketing with CFRP Wrapping. By analyzing
the increased capacity of the member with the retrofitting by using a detailed non-
linear analysis software to prevent the failure and loss in the future.
The result of this mixed retrofitting method is proven to significantly
increase the capacity and performances of the column while effectively using the
minimum space for the retrofitting process. By doing non-linear analysis the
structure is proven to have a detailed assessment that cannot be spotted by the other modeling program.
