1. Comparative analysis of normative provisions for seismic design and detailing of reinforced concrete structures
Resumo O objetivo principal deste trabalho é fazer uma análise comparativa entre os métodos e considerações da norma brasileira ABNT NBR 15421:2006 e as provisões do ASCE/SEI 7 e do Eurocódigo 8, quanto ao dimensionamento sísmico de estruturas. São verificadas as similaridades e as diferenças entre as instruções normativas, quanto à aplicação

2. Experimental and numerical modeling of horizontally-bent buried pipelines crossing fault slip
Abstract The behavior and response of pipelines subjected to slip fault movement is studied by numerical simulations as well as experimental setup. A finite element modeling is also developed via ABAQUS software. In this study, an artificial accelerogram is applied to the system and matched against the response spectrum according to the standard No. 2800 (Ir

3. Dynamic Response of Dam-Reservoir Systems: Review and a Semi-Analytical Proposal
Abstract This paper presents a review of current techniques employed for dynamic analysis of concrete gravity dams under seismic action. Traditional procedures applied in design bureaus, such as the Pseudo-Static method, often neglect structural dynamic properties, as well as ground amplification effects. A practical alternative arises with the Pseudo-Dynami

4. OVERVIEW ON SECONDARY SYSTEM SEISMIC RESPONSE SPECTRA / VISÃO GERAL SOBRE ESPECTROS DE RESPOSTA SÍSMICA PARA SISTEMAS SECUNDÁRIOS
A indústria de geração elétrica de fonte nuclear baseia-se em princípios de segurança e, nos critérios de projeto, considera-se a hipótese de terremoto. Os sistemas necessários à segurança são projetados para resistir e manter a operabilidade durante e após eventos sísmicos postulados. Propõe-se um roteiro para a produção de espectros de res

5. 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

6. STATISTIC EVALUATION OF THE METODOLOGY FOR DETERMINATION OF UNIFORMLY PROBABLE RESPONSE ESPECTRA / AVALIAÇÃO ESTATÍSTICA DE METODOLOGIA PARA DETERMINAÇÃO DE ESPECTROS DE RESPOSTA DE PROJETO UNIFORMEMENTE PROVÁVEIS
Apresenta-se uma avaliação numérica estatística de metodologia para obtenção de espectros de resposta uniformemente prováveis, ERUP, Diniz [2], fundamentada na determinação da distribuição de probabilidade dos valores extremos da resposta de um sistema com um grau de liberdade, submetido a movimentos de terreno oriundos de terremotos. Tais movimen

7. 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

8. AN ALTERNATIVE METHODOLOGY FOR THE SEISMIC STRUCTURAL ANALYSIS OF THERMO-NUCLEAR POWER PLANTS / ALTERNATIVA NA ANÁLISE DE ESTRUTURAS DE USINAS TERMONUCLEARES PARA CARGAS SÍSMICAS / ALTERNATIVA EN EL ANÁLISIS DE EXTRUCTURAS DE TERMONUCLEARES PARA CARGAS SÍSMICAS
The seismic analysis of nuclear power plant structures and components is considered to evaluate the convenience to update the brazilian design routine through the use of frequency domain techniques provided by codes such as SASSI. For this purpose one uses a FEM model of a reactor building which has been already analyzed by current techniques in time domain,

9. Analise dinamica modal espectral de porticos planos
This work presents the modal spectral dynamic analysis of plane framed structures. The Seismic Force is the dynamic excitation acting on structures. A response spectrum, namely, a plot of the maximum response (maximum displacement, velocity, acceleration, or any other quantity of interest) to a specified seismic load function for all possible single degree o
