Reinforcing a P/T Beam
Reinforcing a P/T Beam
(OP)
I posted this on the Concrete Post-tensoned Forum also.
A one-span P/T beam supporting the roof of a parking garage needs be reinforced due to the addition of a new point load at about 1/3 of its span. The capacity of the beam was checked and found being exceeded with the new load. What is the best method for reinforcing the beam? And please comment on the use of carbon fiber sheets as a reinforcing material/method.

Fire is an issue with external fibre reinforced polymer systems, which as far as I know doesn't have a satisfactory solution if fire resistance may be required at the same time as the additional load resistance.
