Abstract :
This paper illustrates an optimization procedure of concrete beam-column joints subjected to
shear that are strengthened with fiber reinforced polymer (FRP). For this aim, five different
values have been considered for length, width and thickness of the FRP sheets which created
125 different models to strengthen of concrete beam-column joints. However, by using
response surface methodology (RSM) in design expert software the number of these models
is reduced to 20. Then, each of 20 models is simulated in ABAQUS finite element software
and shear capacity is also determined. The relationship between different dimensions of the
FRP sheets and shear capacity are specified by using RSM. Furthermore the optimum
dimensions are determined by particle swarm optimization (PSO) algorithm.
