Static tests on two-span continuous GFRP-concrete composite hollow slabs supported on steel girders were conducted to investigate their structural performance. The connections between the steel girders and the GFRP-concrete composite slabs were realized by adhesive connection and mechanical connection,respectively. The observed failure modes for the two specimens were both concrete crushing followed by the bottom flange rupture or side wall buckling of GFRP profiles at the mid-span section. Two external supports for the specimen connected with adhesive connection can be considered as the simply support constraints. However,the fixed support constraints can be approximated for the specimen mechanically connected with shear studs. During the tests,the internal force redistributions were observed after concrete cracking and tensile steel reinforcement yielding at the negative moment regions. Based on the sectional analysis method and sectional equivalent stiffness,a full-process calculation method for the two-span continuous GFRPconcrete composite hollow slabs was proposed. The analytical results show that there is a good agreement between the tested and calculated values of the support reaction and the sectional bending moment,respectively. The proposed method can predict the full-process mechanics of the continuous composite slabs effectively.

The bond strength between fiber rein forced plastic /polymer composites(FRP)sheet and concrete was studied by experiment on a simple shear test s et-up with emphasis on the effects of the bond length,support height,loading offset and FRP-to-concrete width ra tio.The test results were compared w ith those obtained from the Chen and T eng's bond strength formulas.Following c onclusions are drawn from this study:(1)there are two kinds of failure modes,namely FRP debonding failure and con crete tension-shear failure;(2)the bond length,loading offset and FRP-to-concrete width ratio have significant effects on bond strength while the support height also has certain effect;(3)the results obtaind from Chen-Teng' s bond strength formula agree well wi th the test results,provided the total bond length is no less than the effective bond len gth.
