1. Optimum design of steel columns filled with concrete via genetic algorithm: environmental impact and cost analysis
Abstract The use of concrete-filled tubular columns as part of structural systems has steadily increased throughout the years. The growing demand for structural elements of this nature is a direct result of the possibility to use various cross-section shapes that have increased strength, along with resistance to fire and other corrosive agents. The main obje

2. Parameters Determination of Yoshida Uemori Model Through Optimization Process of Cyclic Tension-Compression Test and V-Bending Springback
Abstract In recent years, the studies on the enhancement of the prediction capability of the sheet metal forming simulations have increased remarkably. Among the used models in the finite element simulations, the yield criteria and hardening models have a great importance for the prediction of the formability and springback. The required model parameters are

3. Food mechanics: a new device for testing fruits and vegetables
The new mechanical device developed is capable of performing compression tests but also bending, torsion and tensile tests. Its measurement system has the following components: a load cell (0 to 9800 N), a strain gauge signal conditioning board, a plug-in general purpose data acquisition board, and a displacement sensor (0 to 29.7 mm). These components are c

5. EXPERIMENTAL STUDY ON THE BEHAVIOR OF COMPOSITE COLUMNS SUBJECTED TO COMPRESSION AND BENDING / ESTUDO EXPERIMENTAL DO COMPORTAMENTO DE PILARES MISTOS SUJEITOS A FLEXO-COMPRESSÃO
Composite columns are a structural members subjected to compression and bending, made of concrete and structural steel. One particular type of composite column consists of rectangular steel hollow sections completely filled with concrete and reinforcing bars, which is the type of column considered in this work. One of the advantages of this column is the con

6. Avaliação dos critérios de dimensionamento para peças comprimidas e flexocomprimidas de madeira / Evaluation of design criteria for timber members in compression and in combined bending and axial compression
A recente revisão da NBR 7190/97 culminou em avanços inegáveis no projeto das estruturas de madeira. As excentricidades acidentais, amplificação das excentricidades e efeitos da fluência incidem diferentemente no cálculo das peças curtas, medianamente esbeltas ou esbeltas, estabelecendo descontinuidades nos diagramas de esforços de projeto em funç�

7. Pilares mistos preenchidos : estudo da flexo-compressão e de ligações viga-pilar / Concrete filled steel columns : a study of combined bending and compression and beam-column connections
Este trabalho aborda o estudo de pilares preenchidos flexo-comprimidos e algumas ligações viga-pilar preenchido. Para ambos, são realizadas experimentações com modelos físicos e numéricos, sendo que para os pilares preenchidos um amplo estudo paramétrico foi desenvolvido. Ao todo, foram ensaiados 13 pilares preenchidos flexo-comprimidos, cujos valore

8. Contribuição ao estudo da instabilidade lateral de vigas pré-moldadas / On the lateral stability of precast concrete beams
The lateral stability of long and slender precast concrete beams requires great attention. In particular, it is important to ensure the stability of these members during transitory phases like tilting and transport, and also when the deformability of temporary supports is taken into account. The state of the art of the problem of lateral stability in precast

9. Estudo de desempenho de papelão ondulado virgem e reciclado exposto a diferentes condições de umidade relativa
In many countries corrugated board industry have been forced to improve the quality of recycled material to make it more competitive and to reduce both the needs for virgin material and the problem of waste disposal. However, there is a lack of information about the behavior of recycled corrugated boards when subject to long-term stacking in a cyclic relativ

10. DIAGRAMAS DE INTERACCIÓN PARA EL DIMENSIONAMIENTO DE PILARES ESBELTOS Y SECCIONES DE CONCRETO DE ALTA RESISTENCIA / INTERACTION DIAGRAMS FOR THE DESIGN OF HIGH STRENGTH CONCRETE SLENDER COLUMNS AND CROSS-SECTIONS / DIAGRAMAS DE INTERAÇÃO PARA O DIMENSIONAMENTO DE PILARES ESBELTOS E SEÇÕES DE CONCRETO DE ALTA RESISTÊNCIA.
The use of high strength concrete is already a reality and many countries are adapting their design codes to take into account the properties of this material. For the design of slender columns and sections subjected to combined axial force and bending, the most important property is the stress-strain relationship. While for normal concrete the strain at ult

11. Mechanics of the Compression Wood Response: II. On the Location, Action, and Distribution of Compression Wood Formation 1
A new method for simulation of cross-sectional growth provided detailed information on the location of normal wood and compression wood increments in two tilted white pine (Pinus strobus L.) leaders. These data were combined with data on stiffness, slope, and curvature changes over a 16-week period to make the mechanical analysis. The location of compression
