1. Inelastic second-order analysis of steel columns under minor-axis bending
Abstract The inelastic second-order behavior of steel structural columns under minor-axis bending is presented in this article. To study this behavior, a nonlinear frame element formulation is adopted in which the steel's plasticity process is accompanied at the nodal points of each finite element through the refined plastic-hinge method (RPHM). A tangent mo

2. An accelerated incremental algorithm to trace the nonlinear equilibrium path of structures
This paper deals with the convergence acceleration of iterative nonlinear methods. An effective iterative algorithm, named the three-point method, is applied to nonlinear analysis of structures. In terms of computational cost, each iteration of the three-point method requires three evaluations of the function. In this study the effective functions have been

4. As ligações semirrígidas na análise avançada com zona plástica de portais planos de aço
In this work, the development of the Plastic-Zones Advanced Analysis of plane steel portals is studied, now including the connections effect. Firstly, this analysis is defined as inelastic second-order which capture the plasticity spread by slice technique and includes the Main Aspects as geometric (out-of-straight and out-of-plumb) and physical imperfection

6. Phenomenological analysis of proton-proton and antiproton-proton elastic scattering at high energies / Analise fenomenologica dos espalhamentos elasticos proton-proton e antiproton-proton em altas energias
We present a study on proton-proton (pp) and antiproton-proton (¯pp) elastic scattering at high energies, with focus on the behavior of the total cross section, differential cross section and the parameter p (ratio between the real and the imaginary parts of the forward amplitude). These quantities are described by means of a model independent parametrizati

7. Fiberglass-reinforced glulam beams: mechanical properties and theoretical model
The glued-laminated lumber (glulam) technique is an efficient process for making rational use of wood. Fiber-Reinforced Polymers (FRPs) associated with glulam beams provide significant gains in terms of strength and stiffness, and also alter the mode of rupture of these structural elements. In this context, this paper presents a theoretical model for designi

8. EFFECTS OF THE INTERNAL PRESSURE AND TEMPERATURE VARIATIONS ON SEISMIC RESPONSE SPECTRA OF TUBULAR SYSTEMS / A PRESSÃO INTERNA E A VARIAÇÃO DE TEMPERATURA NOS SISTEMAS DE TUBULAÇÃO E OS ESPECTROS DE RESPOSTA DE PROJETO PARA CARGAS SÍSMICAS
The analysis of secondary structure systems to seismic loads is a special and open subject in the design of industrial installations. Two particular points attract specialist attention and effort on the way of a more realist, comprehensive and economical design: the dynamical properties interaction between the secondary and principal systems and the amount o

9. UNIFORMLY PROBABLE DESIGN RESPONSE SPECTRUM FOR INELASTIC SECONDARY SYSTEMS / ESPECTRO DE RESPOSTA DE PROJETO UNIFORMEMENTE PROVÁVEL PARA SISTEMAS SECUNDÁRIOS INELÁSTICOS
The authors concern includes two main points in the subject of design response spectra generation for secondary systems in nuclear power plant structures: the consideration of inelastic behavior in the secondary systems materials and the production of uniformly probable design response spectra. One works with a previously developed secondary system model att

10. Efeitos de temperatura e de interação finita em sistemas desordenados correlacionados
The main goal of this work is to study the role of disorder in strongly correlated systems, where the electron-electron interaction is comparable to or dominates over the electron kinetic energy. Keeping this in mind, we solve the Hubbard model and the Anderson lattice model in the presence of disorder. The main theory in which our work is based is the Dynam

11. Modeling of the Fluid-Structure Interaction in Inelastic Piping Systems
In many engineering applications, compliant piping systems conveying liquids are subjected to inelastic deformations due to severe pressure surges such as plastic tubes in modern water supply transmission lines and metallic pipings in nuclear power plants. In these cases the design of such systems may require an adequate modeling of the interactions between

12. ELASTIC-PLASTIC HYSTERESIS LOOPS INDUCED BY COMPLEX LOADING / LAÇOS DE HISTERESE ELASTOPLÁSTICOS GERADOS SOB CARREGAMENTO COMPLEXOS
The main objective of this work was to experimentally study the cyclic elastoplastic behavior under complex leading of two structural steels, named API S-135 and AISI 4340. In order to minimize experimental errors, some problems were studied with unusual care. The influence of the residual bending moment on the EN tests was measured, using a special specimen
