摘要: The dynamic behavior of masonry walls strengthened with composite materials and subjected to out-of-plane loading is analytically investigated. analytical model derived in the paper focuses on one-way action through height wall it based equilibrium compatibility conditions between structural components (masonry units, mortar joints, FRP reinforcement, adhesive layers). cracking nonlinear dissipative material, breathing cracks, rocking phenomenon, development arching forces, interaction existing system, formation debonded zones near cracked joints are considered analysis. A numerical study that examines capabilities model, quantifies response loads such as free forced vibrations seismic base excitation, compares unstrengthened presented. summary conclusions close paper.
