  • To avoid the relatively cumbersome strength-testing methods for the existing masonry structures under the combined action of shear and compression, an improved test device substituting uniaxial loading for biaxial is provided to test masonry shear-compression strength under different stress ratios by means of angular rotation of specimen. Comparing the experimental phenomena and numerical analysis results, sliding failure, tensile failure and compression failure of masonry are presented and the failure criterion of shear-compression strength under different stress conditions is established by means of the three-stage shear compression correlation curve with turning points of 0.2 and 0.6, and the stress-strain relationship with turning points of 0.2 under the shear-compression state is proposed. Results show that the improved testing method is simple, efficient and small in error. The mean value of the ratio of theoretical calculation to test result is 1.07, and the coefficient of variation is 0.180. The testing results enrich the constitutive relationship of masonry material, which can provide a theoretical basis for the improvement of masonry failure criterion and the construction of numerical analysis model.
