Original Abstract

Methods of external strengthenin of concrete use elements of very high tensional strength glued on tensioned surface of it. These elements may be of metal, carbon fibers (CFRP), glass fibers or others, being ordinarily of very good mechanical properties. But these high strength elements are attached to concrete mostfrequently by epoxy resins. However, epoxy resins are of low Young´s modulus and therefore a higher rate of creep might have influence on long-term behaviour of such external strengthening. In order to verify this idea experimentally, special space saving arrangement of tests is described. Panels act like loaded beams and simultaneously like a load for the others of them in a stand. Different load magnitude acting on different layr of panels should make possible to study the long-term influence od degree of shear force on the glue creep. The glue creep may be dependent on type of epoxy resin; therefore more types of it are included in tests.
