1. Seismic Design and Performance of Dual Moment and Eccentrically Braced Frame System Using PBPD Method
Abstract Most structural design codes use elastic analysis to calculate and distribute seismic base shear over the height. This may lead to unsuitable design and may cause undesirable damages to the structure. To solve this problem, in recent years the Performance-based Plastic Design (PBPD) method which considers the plastic behavior of the structure, has b

2. Severe Loading Assessment of Modern and New Proposed Beam to Column Connections
AbstractThe performance of two different steel beam to column connections known as SidePlateTM and a new proposed connection by seismic loading and progressive collapse were investigated in this research. Seismic performance evaluated included consideration of interstory drift angles and flexural strengths based on 2010 AISC Seismic Provisions while investig

3. Study of alveolar beams with emphasis on collapse modes by yielding / Avaliação do comportamento de vigas alveolares de aço com ênfase nos modos de colapso por plastificação
Vigas alveolares são normalmente obtidas a partir de perfis laminados cortados ao meio em zigue-zague, deslocadas e soldadas novamente de forma a obter perfis com maior altura e mesmo peso. Neste trabalho são apresentados os resultados de uma análise numérica não-linear realizada com vigas alveolares de aço utilizando o programa ABAQUS. O enfoque princ

4. Análise de criticidade de descontinuidade em um bocal de um vaso de pressão
Pressure vessels and pipes are essential equipment in the chemical, petrochemical, petroleum refining, among others. The safety operation of this equipment is an important aspect, since failures can vary from large financial losses to catastrophic consequences. Evaluation discontinuity found in inspections can be perfomed by fitness for service methodology w

5. Degradation of the compressive strength of unstiffened/stiffened steel plates due to both-sides randomly distributed corrosion wastage
The paper addresses the problem of the influence of randomly distributed corrosion wastage on the collapse strength and behaviour of unstiffened/stiffened steel plates in longitudinal compression. A series of elastic-plastic large deflection finite element analyses is performed on both-sides randomly corroded steel plates and stiffened plates. The effects of

6. Avaliação da rigidez de pórticos tridimensionais de concreto armado / Evaluation of stiffness in three-dimensional frames of reinforced concrete
An evaluation of stiffness in three-dimensional frames is important to ensure safety in structural projects, especially in tall buildings, where both ultimate limit state and serviceability limit state have to be considered. In reinforced concrete buildings, this evaluation is calculated through an analysis of global stability, either through approximate met

7. ANÁLISE ELASTOPLÁSTICA VIA MEF DE PROBLEMAS EM SOLOS REFORÇADOS
Reinforced earth structure is a composite system that involves basically three components: the soil, the reinforcement and the soil-reinforcement interface. The performance of the reinforced structure will depend on the interaction among these components. This interaction can be studied by monitoring a sufficiently large number of full scale field tests, lab

8. Desempenho dos modelos da nbr-6118 para anÃlise de vigas contÃnuas em concreto armado
Continuous beams are essential to structural solutions to buildings, bridges and walkways. Collapse in flexure does not necessarily occur when critical section reaches its strength capacity. Due moment redistribution collapse may occur when a sufficient number of plastic hinges transforms the structure into a mechanism. On the other hand, in order to develop
