O objectivo do presente trabalho é o da divulgação da actividade de normalização e do seu enquadramento no seio do Sistema Português da Qualidade. São abordadas três vertentes de normalização, portuguesa, europeia e ...

A aderência constitui uma das características mecânicas fundamentais dos varões de aço nervurados para o bom desempenho dos elementos de betão armado onde estes varões são utilizados, assegurando a transmissão de ...

The use of adhesives to produce assembled structural joints in the building industry is increasing, particularly in the context of on-site rehabilitation of timber structures. On their own or together with steel or fibre ...

Traditional buildings basically include natural and autochthonous construction materials and are built with sustainable construction techniques. The knowledge of these materials’s state and construction techniques is ...

This study investigates the possibility of using agro-industrial wastes for building products, mainly focusing on their insulation properties. A classification of bio-wastes is provided, namely of the lignocellulosic ones ...

Bridge falsework systems are used to support the formwork during the construction of concrete bridges. Relevant stakeholders often do not consider them as important as permanent structures, and in recent years a high number ...

In the recent codes for the design of steel structures, the elastic–plastic methods of analysis are recognised to provide an efficient estimation of the ultimate resistance of some of these structures. These methods are ...

The development of “full plastic hinges” in the most stressed cross-sections is a common hypothesis considered in the elastic–plastic design of steel structures. The equations for the internal forces at the plastic limit ...

This paper presents the analytical relationships of a non-linear model for the in-plane elastic–plastic analysis of bi-symmetrical steel shapes bent about one of their main axes. The basic variables are the cross-section ...

An analytical model allowing the mechanical behaviour of simply supported beams under concentrated transversal loads to be evaluated, is presented in this paper. The beams are made of I-sections. The constitutive material ...
