We are now releasing the October 2016 issue of the IBRACON Structures and Materials Journal (Volume 9 Number 5, October 2016). This issue brings eight articles on concrete structures and materials. The first article deals with an evaluation of the interaction between strength concrete block walls under vertical loads. Experimental analysis was performed on full-scale H-shaped flanged walls. The next article presents a study on safety of reinforced concrete beams subjected to bending moment and designed with the partial safety factors proposed by ABNT NBR 6118:2014. The third article discusses the behavior of deep beams using short straight bars anchorages. Results from tests performed on 12 deep beams using three different shear span-to-depth ratios, indicated that short bar anchorages did not seem to influence significantly the shear strength of the deep beams tested. The fourth article aims to study the structural concrete dosage in construction sites. In another article, results of an experimental research on bond stress-slipping in Brazilian reinforced concrete, using five different concrete strengths (20, 40, 60, 80 and 100 MPa) and two different rebar diameters (16 and 20 mm). The sixth article reports a study on Mortar modified with sulfonated polystyrene produced from waste plastic cups. The influence of polystyrene in the mortar properties was evaluated by consistency index, water retention, water absorption, porosity, elasticity modulus, compressive strength, flexural strength, and bond tensile strength. The sevenths article discusses the influence of the cable shape on the shearing resistance of prestressed concrete beams. The issue closes with an article on an experimental study of column reinforcement using anchor bolts and self-compacting concrete.
All the articles were reviewed by specialists from many Institutions in Brazil and abroad. Their contribution, fundamental for the quality of our Journal
