An experimental investigation on five concrete beams
prestressed with external
aramid tendons was carried out for the purpose of studying
the influence of concrete on
the flexural behaviour at service and ultimate loads. The
beams were prestressed with
Type G Parafil tendons, which are made of Kevlar 49 fibres.
The strength and elastic
modulus of the cables are 1950 MPa and 12600 MPa
respectively.
The main variable considered in the testes was the strength
of the concrete with
values of 36, 57, 73, 74 and 104 MPa. The results show that
for an increase of 189% in
the strength of the concrete, an increase of only 33% in
the ultimate moment is
observed. Experimental results were compared with results
predicted by some Codes of
Practice. This comparison shows that the theoretical models
give good results.
