A new genetic algorithm-based framework for optimized design of steel-jacketing retrofitting in shear-critical and ductility-critical RC frame structures

Abstract

A new specific optimization framework addressing the minimization of seismic retrofitting-related costs is developed and presented. A new genetic algorithm routine is defined by developing modified genetic operators capable of addressing retrofitting optimization both for RC structures with ductility-critical and shear-critical RC columns.

Highlights

  • A new genetic-algorithm based framework to optimize retrofitting interventions in RC structures is presented.
  • The method minimizes retrofitting-related costs for steel-jacketing of reinforced concrete columns.
  • The framework efficaciously provides retrofitting optimization for RC structures with shear and ductility lacks.
