EXTRA NOTES ON TBEAM ANALYSIS
The analysis of a Tbeam section in positive bending must consider whether the
compression is limited to the flange or whether it extends into the web two
analysis cases are possible.

FRP REINFORCED TBEAM ANALYSIS
When doing a flexural analysis of a
FRP reinforced section, we would
like to know the failure mode
(Tension or Compression) before we
begin the analysis since the analysis
