Modelling CFRP patch on Beam-Column Joint

[zsaeed]

Hi
I am modeling a Beam-Colum joint in seismostruct which is later on tested and wrapped with CFRP (Carbon Fiber Reinforced Polymer) for again retesting under same load conditions as shown in Figure ( click the link below)

How can i model this CFRP patch configuration or calculate its confinement factor becaue the dialuge box that apears in seismostruct asks for input which assumes that the CFRP is wrapped entirely over the whole surface of the concrete and producing the confinemnt effect.

Dear zsaeed,

I cannot understand the configuration of the CFRP sheets from the uploaded 2D figure. However, I would like to mention that the confinement factor of an RC element is increased when the FRP sheets are properly anchored.
