Study of Materials Behavior in a Monumental Vault Strengthened by a Carbon Net in a Mineral Matrix Subjected to Seismic Influence

The application of the elasto-plastic material model known as Barcelona Model (BM) for numerical assessment a historical vault subjected to earthquake sequence is presented in this work. As case study, part masonry erected Southern Poland 12th century was chosen. For study purposes, 3D finite element (FEM) prepared using ABAQUS/Standard software program. essential details structure geometry were taken from scan vault. first variant without any strengthening, whereas second with strengthening system realized by on composite materials, i.e., carbon fiber reinforced cementitious matrix (C-FRCM). results dynamic analysis revealed that an evident nonlinear performance materials both cases detected FE models structure. proved foreshock–mainshock–aftershock caused substantial damages structural parts distribution plastic strains and allowed impact full seismic In unstrengthen level cracking stiffness loss reached 90%. strengthened FRCM tensile damage significantly lower. It did not exceed 30%. addition, zone unstrengthened elements became visible after foreshock.
