The three point bending test, according the Brazilian Standard ABNT NBR 7190, enables to identify the values of two wood properties: conventional modulus of elasticity and conventional strength on static bending test. With the results, this study aimed to perform a numerical simulation using the finite element software ABAQUS and the experimental results of three point bending test using Simarouba amara Aubl wood specie test proofs. Two analysis were performed, considering wood as elastoplastic material in the first and the second, considering only elastic material. From stress-strain diagrams results, it was observed the evaluation of modulus of elasticity on static bending test is not valid due to material non-linearity. A constitutive model was proposed for Simarouba amara Aubl. wood specie and for evaluation of modulus of elasticity on static bending. It was performed a comparative analysis between experimental results and the proposed constitutive model. These models showed their efficiency when evaluated the normal stress on proof test with demonstrated accuracy, allowing its use by wood structures designers.

ZusammenfassungBei der fleischhygienischen Untersuchung eines 17 Monate alten Stiers (Deutsches Fleckvieh) fiel eine ungleichmäßige Schwarzfärbung verschiedener Gewebe auf. Besonders auffällig war das perirenale Fettgewebe. Die histopathologische Untersuchung ermöglichte die Diagnose einer Melanose im Sinn einer kongenitalen melanozytären Dystopie. Nach Kenntnis der Autoren ist die Melanose von Fettgewebe beim Rind bislang nicht beschrieben worden. Ein Zusammenhang zwischen Adipositas und Pigmentanomalie wird diskutiert.

This review article presents a state-of-the-art survey on timber-concrete composite (TCC) bridges. It starts with a presentation of a sample of relevant TCC bridges, offering a global perspective on the use of this type of bridge. The number of TCC bridges has clearly increased in the past few years, and some of the reasons for this trend are explored. Next, an extensive literature review is presented regarding the most significant technological innovations and recent developments in the application of TCC structures to bridge construction. Firstly, the engineering specificities and the advantages of TCC bridge structural systems are enumerated. Afterwards, the importance of proper mechanical connection for optimal performance of TCC structures is explained, and a thorough description of the connection systems suitable for bridge construction is provided. Some research into the structural behavior of TCC bridges under service conditions is then presented and discussed. Finally, possible areas of future research regarding the development of TCC bridges are suggested.
