The dynamic in-plane shear stress-strain response of a unidirectional non- crimp fabric carbon fiber/snap-cure epoxy composite was studied by subjecting 30° and 45° off-axis specimens to compression loading at high strain rates. Tests were performed using a compression split-Hopkinson pressure bar apparatus where an approximate axial strain rate of 305 s-1 was achieved. Images of the deformed specimen surfaces were captured with high-speed cameras and digital image correlation used to obtain a strain map. Pulse shaping was performed using a copper pulse shaper to achieve dynamic equilibrium during the high-rate tests. The results demonstrated that the in-plane shear yield stress and strength increased by 53% and 68%, respectively, when the strain rate increased from quasi-static to 305 s-1.

Shear Performance

To overcome the shortcoming of unreinforced masonry (URM) structure, structural columns are added in its construction to avoid the sudden collapse. This kind of structures still suffers different degrees of damage in the earthquake. This paper assesses the in-plane shear behavior of masonry walls with structural columns retrofitted with FRP (fiber reinforced polymer). The tests of two half-scaled masonry walls under cyclic loading have been carried out. One wall was served as reference specimen without any retrofitting scheme. Another specimen was tested to the pre-defined damage level and then strengthened with FRP sheets in mixed retrofitted configuration. The shear behavior of retrofitted specimen was discussed and compared with the reference in the aspect of lateral shear strength, maximum displacement and energy dissipation.
