Abstract:
The behaviour of concrete elements, in this case the beams under the different loadings
result with the capacity of section. In analyzing process results are followed with the
deflections of beams and the cracks. In this paper we analyse the type, form and dimensions
of cracks under the third point load method of applied loads in simple concrete beam. To
improve the capacity we use the different types of FRP, including the GFRP and CFRP,
comparing the deflections and cracks. The focused parameters are in using the different
methods for transversal force , including the primary forms with steel stirrups and the new
proposal for using the outside stirrups from FRP. The all analyses presented in this paper are
based on the analytical model and experimental results.
The behaviour of beams under the mixed form with ordinary steel stirrups and proposal
stirrups from FRP, successfully increase the energetic capacity of sections.
