Editorial

We are now releasing the second issue of the third volume of our IBRACON Structures and Materials Journal (Vol. 3 Num. 2). In this issue an investigation on the ductility of reinforced concrete beams is reported in the first article. Material nonlinearity of concrete structures is the subject of the second article, in which design procedures based on lumped dissipation models are compared with simplified procedures recommended by the Brazilian code NBR 6118. In a third article, monitoring techniques are employed to compare design assumptions to actual behavior of reinforced concrete columns of tall buildings The fourth article presents mechanical properties of lightweight concrete, with a comparison to the corresponding properties of normal concretes. A teaching tool for studying skew bending for general concrete cross-sections is described in the fifth article. The following article presents an attempt to classify environmental aggressiveness in the city of Salvador, BA. The issue closes with an article addressing the aerodynamic behavior of cable stayed bridges under simultaneous action of rain and wind.

The articles have been carefully reviewed by the Editorial Board and highly qualified reviewers from Brazil and from abroad. We deeply acknowledge their contribution, fundamental for the ever improving quality and regularity of our Journal. We would also like to thank all the authors that submitted articles for publication in our Journal, and renew the invitation to the whole concrete community, in Brazil and abroad, to actively participate in the life of the IBRACON Structures and Materials Journal, as frequent readers or as contributors.
