1. Efeitos dependentes do tempo em vigas pré-moldadas compostas com lajes alveolares e vinculações semi-rígidas / Time-dependent effect on composite precast beams with hollow core slabs and semi-rigid connections
Neste trabalho estudam-se os efeitos dependentes do tempo em vigas de concreto pré-moldado, protendidas ou não, com concretagem posterior formando um conjunto de seção composta com lajes alveolares, usual em pavimentos de edifícios, e ocasionando um estabelecimento da continuidade com ligação semi-rígida. Os esforços de restrição causados pelos ef

2. On the behaviour of single-span steel beams under uniform heating
Structures’ load resistance is reduced when subject to high temperatures in fire. Nevertheless, it is not enough to take into account strength and modulus of elasticity reduction. One must know with great accuracy the behaviour of the structures including the realistic boundary conditions at high temperatures, in order to determine for safe and of low cost

3. Análise numérica do comportamento estrutural e da resistência de terças de aço restringidas pelas telhas / Numerical analysis of cold-formed purlin-sheeting systems focused on the structural behavior and strength
The structural behavior of purlin-sheeting system is complex and the complete analysis should consider the physical and geometrical nonlinearity, as well as the influence of the purlin-sheeting contact and connection. The brazilian code NBR 14762:2001 provides a design procedure to consider the interaction between a purlin or girt connected to the sheeting (
