This study also shows that it is possible to obtain high quality SCC (with no risk of segregation) with screen stability test values in the region of 30%, which are much greater than the usual 15% recommended pat the French association of civil engineering AFGC [1].
It should be noted also that French Association of Civil engineering [1] recommends, for the characterization of resistance to segregation, the “test of stability into the sieve”.

As the progress of theory and computer technology, nonlinear analysis is widely applied in civil engineering.
Appling the results of nonlinear analysis of reinforced concrete structures to engineering practice as soon as possible would provide the basis to save investment and improve economic efficiency for the construction of various projects.

Through the analysis of test data,it is concluded the relationship of the bond strength and the concrete cover thinkness.And basis on the relationship,it is determine the suggestive values on concrete cover thinkness of GFRP.Experimental data and suggestion can provide reference and theoretical basis for the GFRP engineering application and the establishment of the relevant specification.
In recent years at home and abroad, GFRP and concrete structure has been launched in the field of civil engineering applications[3].
