Experimental characterization of masonry and masonry components at high strain rates
The strain rate effect influences the mechanical properties on most construction materials and its investigation is critical for structural engineering. Current materials such as steel or concrete have been intensively investigated. However, similar studies on the dynamic properties of masonry or masonry components such as clay brick or mortar are scares. This work intends to study the behavior of masonry and its usual components (clay brick and mortar) when subjected to high strain rates. A Drop Weight Impact Machine is used at different heights and weights introducing different levels of strain rate. Empirical relations of Dynamic Increase Factors (DIF) are derived from the experimental results and the strain rate effect on compressive strength, compressive fracture energy, strain at peak strength and Young’s modulus are determined and presented. ; This work was performed under Project CH-SECURE funded by the Portuguese Foundation of Science and Technology – FCT. The authors acknowledge the support. The first author also acknowledges the support from his PhD FCT grant with the reference SFRH/BD/45436/2008.
