Abstract in Portuguese
Esta pesquisa apresenta o comportamento estrutural da Catedral da Sé de São Paulo em termos de deslocamentos e de tensões a partir do desenvolvimento de um modelo numérico tridimensional simplificado e da consideração do comportamento elástico-linear dos materiais. Construção gótica do século XX, a igreja matriz é um símbolo religioso, arquitetônico e social e sua praça, palco de manifestações e de expressão popular. Seu estilo gótico e o céu abobadado são interrompidos por um espaço octogonal sobre o qual se ergue uma cúpula renascentista. Inicialmente, são abordados aspectos da arquitetura da igreja e seus principais espaços são descritos; também são apresentadas as características geométricas dos elementos estruturais e as características mecânicas dos materiais, bases para a construção do modelo matemático. Em seguida, a estrutura da igreja é analisada quanto aos deslocamentos e às tensões, tendo-se feito, além do estudo da Catedral tal qual ela é, simulações em que são retirados os arcobotantes e as torres frontais, o que permite um estudo qualitativo e quantitativo da importância destes elementos estruturais para o equilíbrio do conjunto. Verifica-se que as regiões da igreja que apresentam os maiores deslocamentos também são aquelas mais críticas em termos de tensão, e algumas fissuras encontradas na igreja podem ser relacionadas aos carregamentos considerados nesta pesquisa. Constata-se que a Catedral da Sé é bem concebida e que seus elementos principais comportam-se estruturalmente como os das catedrais góticas originais.

Abstract in English
In this research, the structural behavior of the Cathedral of Sé in terms of displacements and stresses is presented, based on a simplified three-dimensional numerical model and the consideration of linear-elastic behavior of materials. Gothic building of the twentieth century, the Cathedral of Sé is a religious, architectural and social symbol and its square, scene of demonstrations and popular expression. Its Gothic style and vaulted sky are interrupted by an octagonal space on which stands a Renaissance dome. Initially, different aspects of the architecture of the church are discussed and its main areas are described, as well as are presented the geometric characteristics of its elements and the mechanical properties of its materials, bases for the construction of the mathematical model. In the sequence, the structure of the church is analyzed in terms of displacements and stresses, and in addition to the analysis of the Cathedral as it really is, simulations in which the flying buttresses and the front towers are removed are done, since they allow for the determination of the qualitative and quantitative importance of these structural elements to the equilibrium of the church. This research shows that the regions of the church in which the largest displacements occur are also those most critical in terms of stresses, and some of the cracks found in the building may be related to the loads considered in this study. The analysis done shows that the Cathedral of Sé is well designed and that its main elements behave structurally as those of the original Gothic cathedrals.
