Axial Compression Behavior of Masonry Prisms Considering the Influence of Mortar

Abstract:

As one of most widely used structure, the behavior of masonry is influenced by its composition especially the mortar. In this paper, a series of compression tests was carried on masonry both with mortar (MP_m) and without mortar (MP_ds). Based on the results, the ultimate compression strength and elastic modulus has been compared firstly; after that, the failure mode of each prism was achieved, finally a finite element model was built for the numerical analysis on MP_ds. Results showed that compared with the MP_m, the elastic modulus of MP_ds has been reduced 30% which means the erosion of mortar should be considered when research on the historic masonry structures. The finite element model can simulate the compression strength and failure mode accurately, which showed great potential for the further parametric analysis.
