Optimal seismic retrofitting of reinforced concrete buildings by steel-jacketing using a genetic algorithm-based framework

Abstract

This paper presents an optimization framework aimed at the minimization of seismic retrofitting-related costs by an optimal placement and amount of steel-jacketing reinforcement. In the proposed framework a 3D RC frame fiber-section model implemented in OpenSees is handled by a genetic algorithm routine.

Highlights

  • A new framework for the optimization of steel jacketing retrofitting interventions on RC columns is presented.
  • The method can provide topological optimization (location) and amount of steel-jacketing reinforcement.
  • The framework can be used by practitioners as a tool for sustainable retrofitting interventions.
