Conventional non-reinforced concrete is a brittle material with a low tensile strength and low strain capacity. To improve these mechanical properties of concrete, fibers have been used in the last decades in structural engineering applications in Colombi... see more

As environmental issues become increasingly important, the buildings have focused on energy efficiency and energy needed for the construction and production of material. This research shows a simplified life cycle analysis study of operational and embodie... see more

This work studies the factors that impact on the fire resistance of stud connections in steel–concrete composite structures, considering beams with solid slab. The design of the experiment, the thermal modeling of the push-out specimens, with or without f... see more

The critical length of grade on two-lane rural roads is used as criterion to assess the need of ascending lanes for heavy vehicles. To estimate it, a speed profile is needed, which depends on the road’s grade and length, and on the physical, dynamic and m... see more

In this work, the behaviour of stud shear connectors in composite structures is studied, starting from the via numeric simulation of the push out test in a steel beam – with solid concrete slab concrete section is studied. The study considers material non... see more

The wood construction industry requires data of the mechanical strength of wood with dimensions and classification suitable to be used as structural elements. This research proposes an experimental strategy for the mechanical characterization of wood beam... see more
