A importância da análise estrutural dinâmica / Beatriz de Carvalho Bessa

Abstract

The technological advancement in civil construction has allowed for ever larger and innovative enterprises with increasingly adaptable materials and better manufacturing control. Thus, buildings, bridges, footbridges, and stadiums are expected to be safer and more resistant. However, the recurrence of structures with vibrations and damage, leading to the collapsing of some of them, remains a concern about the effectiveness of the design calculations. So, this work underscores the importance of using more accurate mathematical analysis, with broader and more assertive considerations, for example, dynamic structural analysis, enabling efficient solutions for buildings, especially large ones. The influence of so-called dynamic loads on the behaviour of structures is highlighted in the cases presented in this text. The Rio-Niterói bridge and Maracanã stadium cases were better detailed to demonstrate how the dynamic analysis helped to understand the problems that occurred and allowed us to propose solutions, as well as to verify the competence of the proposed solutions.
