PIC (Polymer Impregnated Concrete) have a high duraiblity. Form works of concrete structure can be deleted by using PIC as embedded forms. This paper deals with the collapse behaviours and deformation capacity of PIC tied arch structures in order to use PIC boards as embedded forms. Three specimens, which consists of PIC having three types tie (steel, steel strand and FRP rod), are tested up to the failure under the monotonic loading condition. Test results show that load-deformation curves are linear, crack is first generated in the lowersurface of arch crown, next in the upper surface in a quarter of arch span, and then the specimensare failured. Two and three dimensional FEM analytical results were compared with the experimental results. Furthermore, application of shallow hybrid structure to RC slab in composite two plate girderbridge are discussed.
