Resumo: | Despite the remarkable longevity of heritage constructions, they typically present several structural fragilities inherent to their own material and constructive features. This fact is particularly relevant when seismic loads are concerned, because a very significant portion of such constructions lack adequate seismic resistance and require retrofitting interventions in order to mitigate their vulnerability. However, to guarantee the success of the interventions, the interventions should be carefully selected based on a full understanding of the dynamic response of the building and, particularly, its most vulnerable structural elements. Due to many reasons, the issues associated with this kind of analysis are still difficult to address; therefore, research on this subject should be encouraged. Taking this into account, the church of Santa Maria de Belém, one of the most emblematic buildings of the monastery of Jer´onimos complex in Lisbon, is used in this work as a case study to discuss the nonlinear dynamic response of cultural heritage buildings. The nonlinear dynamic behavior of the church was numerically simulated with a three-dimensional (3D) model using artificially generated seismic acceleration time histories, in agreement with seismic hazard scenarios for return periods of 475, 975, and 5,000 years. The dynamic response of the church is discussed and a comparison against results derived from a pushover analysis is also presented. Finally, a modal analysis is presented, estimating the damage level that would be present in the church after the occurrence of such seismic scenarios. |

Despite the remarkable longevity of heritage constructions, they typically present several structural fragilities inherent to their own material and constructive features. This fact is particularly relevant when seismic loads are concerned, because a very significant portion of such constructions lack adequate seismic resistance and require retrofitting interventions in order to mitigate their vulnerability. However, to guarantee the success of the interventions, the interventions should be carefully selected based on a full understanding of the dynamic response of the building and, particularly, its most vulnerable structural elements. Due to many reasons, the issues associated with this kind of analysis are still difficult to address; therefore, research on this subject should be encouraged. Taking this into account, the church of Santa Maria de Belém, one of the most emblematic buildings of the monastery of Jer´onimos complex in Lisbon, is used in this work as a case study to discuss the nonlinear dynamic response of cultural heritage buildings. The nonlinear dynamic behavior of the church was numerically simulated with a three-dimensional (3D) model using artificially generated seismic acceleration time histories, in agreement with seismic hazard scenarios for return periods of 475, 975, and 5,000 years. The dynamic response of the church is discussed and a comparison against results derived from a pushover analysis is also presented. Finally, a modal analysis is presented, estimating the damage level that would be present in the church after the occurrence of such seismic scenarios. |
