Analytical and experimental dynamic analyses of the wooden floor are performed and the results are presented. Test results showed that the natural frequency values coming from the experiments differ considerably from those coming from the analytical studies due to the material characteristic values taken into consideration. An automatic comparison of vibration mode shapes obtained by finite element analysis and experimentally is made in order to calibrate de FEM model. By calibrating the FEM model using results from the vibration modal identification, an assessment of the structural system parameters can be obtained. The automatic model updating procedure highlighted the real elasticity modulus of the wood used, identified by testing wood specimens.

However, since the tensile strength of masonry is low, under certain loading conditions the masonry vaults are vulnerable to cracking and dangerous failure mechanisms. The strengthening systems based on textile glass fibre reinforced polymer (GFRP) composite materials have favourable effects upon the structural response and load bearing capacity of framing systems made of masonry. In this paper the results of an extensive study including testing and numerical programs on structural behaviour and failure mechanism of unstrengthened and strengthened vaults are presented. A comprehensive study program, including numerical modelling and extensive tests, has been conceived and performed to fully characterize the dynamic/seismic behaviour of the masonry unstrengthened and GFRP composites strengthened vaults. The overall behaviour and the failure mechanism have been favourable modified by GFRP strips network improving the structural characteristics, the global seismic behaviour and the failure mechanisms.

Masonry as a structural material has high compressive strength and versatility, in achieving different architectural shapes. Since the tensile strength of masonry is very low, under certain loading conditions, the masonry arches are vulnerable to cracking and to various failure mechanisms. Previous theoretical and experimental studies have proven that the use of textile glass fibre reinforced polymer (GFRP) composite materials has favorable effects upon the structural behaviour and the load bearing capacity of the structural elements. In this paper the results of an extensive experimental program on the structural behaviour and failure mechanisms of unstrengthened and strengthened masonry arches are presented. The experimental results describe the mechanical behaviour of circular masonry arches under vertical and horizontal loadings. The strengthening scheme has been conceived in two phases, on one side only and on both sides of the arch, with the connecting strips made of textile GFRP composites. The overall behaviour and the failure mechanisms have been favorably modified improving the load bearing capacity of the masonry arch type elements.
