members in historical buildings with new innovative technology, which
have lost parts of their strength due to heavy loads, loading time factor,
effects of extreme humidity or insects attack. Most of the ancient buildings
throughout Iran have been constructed mainly by wooden members. Some of
the structural members in such a valuable buildings are partially defected.
Therefore, it seriously needs to be repaired or rehabilitated in order
to maintain in proper strength. Present research is focused on strengthening
the old wood beam members sampling from non-essential sections of historical
buildings with Glass Fiber Reinforced Polymer (GFRP) composite materials.
A three-point loading test was used to study the behavior of the beam
subjected to gradual static load under different configurations of reinforcement.
The load-displacement response, ultimate strength, modulus of elasticity
and the mode of failures were evaluated. The experimental results have
shown an improvement in load capacity, strength and stiffness of hybrid
if compared with un-reinforced samples. At the end, the experimental and
analytical results were compared with each other.]]>Amy, K. and D. Svecova,200431943955Bazan, I.M.M.,1989236773Borri, A., M. Corradi and A. Grazini,200536143153Buell, T.W. and H.
