Finite Element Modeling of FRP-Strengthened RC Beam under Sustained Load

Table 4

Immediate response at midspan of the test beam.

Results	Deflection (mm)	Strain of tension steel bar ()	Strain of compression steel bar ()	Strain of CFRP plate ()	Strain of top concrete ()
Test	3.57	878	−129	937	−277
FE model	3.68	785	−137	845	−248
Theor./exp.	1.03	0.89	1.06	0.90	0.89

Note. Theor./exp. in the above table refers to the ratio of result predicted by FE model and test result, which reflects the predicting error.
