Valorization of industrial low-value side-streams are of great interest, contributing to boosts in the circular economy. In this context, lignin side-streams of the pulp and paper industry were oxypropylated to produce biobased polyols and tested in

The main concern of the fire regulation with the occurrence of fire is not related to the interest of preserving the patrimony, but rather to ensure that the structure remains with its preserved carrying capacity for a period of time considered suffi

A new engineering practice in modern buildings is to use beams with web openings to allow the passage of services within the depth of the beam instead of underneath the beam. As the web post failure may occur before the section reaches the limiting t

Computational modelling of cold-formed steel screwed connections at ambient and elevated temperatures

Autor: Rui Dias, L.M.R. Mesquita, P.A.G. Piloto, Armandino Parente

The application of cold-formed steel structural members in steel construction, and in particular building construction, has a number of advantages that includes its high structural efficiency compared to the member weight. In recent years the increas
