Abstract：The glass fiber reinforced(GFRP) plastic material has many characteristics such as high intensity，large ductility，resisting erosion，simple construct technology，etc.. In order to improve bearing capacity of structure and extend the expiration date，the GFRP is used to rebuild and reinforce common civil building structures. In the same time，the domestic and overseas scholars pay more attention to the characteristics about the complex structure of GFRP and reinforced concrete under static loading gradually，and have obtained many achievements. The application of complex structure characteristics of GFRP and concrete under dynamic loading is initiated. In order to study the strengthening effect and mechanism of GFRP on RC (reinforced concrete)structures under explosion load，the explosion resisting performance of RC slabs reinforced with GFRP ribbon and that the common RC slabs are simultaneously studied. The deforming processes of GFRP reinforced concrete slabs and those of the common concrete slabs under explosion loading are also studied. The test results indicate that GFRP can control the development of concrete flaw effectively and enhance the explosion resisting performance of RC slab，which can provide reference to reinforcement mechanism study of GFRP and explosion resisting design of RC slabs reinforced with GFRP.
