This study analyzed the main mechanical properties of ancient masonry materials and the stress-strain relationship of ancient brick masonry under uniaxial compression. Based on the experimental data, a constitutive relationship and formulas for elastic modulus of ancient brick masonry were established. The findings provide a theoretical basis for finite element simulation and durability evaluation of ancient masonry structures.
Through uniaxial compressive strength tests on glutinous rice mortar, ancient bricks, and ancient brick masonry, the main mechanical properties of ancient masonry materials and the stress-strain relationship of ancient brick masonry were analyzed under uniaxial compression. Based on the compressive strength of the masonry, compressive strength of a single brick, and compressive strength of the mortar, the constitutive relationship of the ancient brick masonry in the Shanxi Province of China and the formulas for elastic modulus was established. The results reveal that the constitutive relationship of masonry under axial compression can satisfactorily fit the experimental data obtained for masonry under axial compression. The model provides a theoretical basis for the finite element simulation and durability evaluation of ancient masonry structures in the Shanxi Province of China.
