The inclusion of ductility requirements is necessary to guarantee a safety design of concrete structures subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may develop in columns ...

Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ...

This study focuses on analysing the effects of nonlinear torsional stiffness on the dynam-ics of a slender elastic beam under torsional oscillations, which can be subject to helical buckling.The helical buckling of an ...

Previous earthquakes, such as the 2010 Maule earthquake in Chile, have demonstrated the need to establish suitable predictors of compressive or tensile strains in concrete or steel in reinforced concrete shear walls, which ...

The resistance to compression is the property that determines the use of masonry as a structural system since the great majority of structural elements in such systems are generally subjected to compressive stresses. One ...

We report the first data on nesting ecology of the Slender-billed Parakeet (Enicognathus leptorhynchus) from two wild nests in native temperate rainforests of southern Chile. Nests were located in natural cavities 19 m up ...
