Core testing method to assess nonlinear behavior of brick masonry under compression: A comparative experimental study

This study investigates the applicability of the core testing method to assess the complete nonlinear behavior of masonry in compression. A comparative experimental approach was adopted performing compressive tests on cores and companion wallets. Via a correlation study on seven objects, including literature data, a one-to-one correlation for both compressive strength and Young's modulus is obtained, while further studies are necessary to evaluate peak strain and compressive fracture energy. Thanks to its limited invasiveness and the capability of capturing the post-peak response with standard equipment, the core testing method can be regarded as a practical alternative to conventional slightly-destructive techniques.
