1. Numerical Study on Steel Shear Walls with Sinusoidal Corrugated Plates
Abstract Over the past decades a growing demand and interest has stimulated many researchers to investigate different aspects of steel plate shear walls (SPSWs). The structural performance of steel shear walls with sinusoidal corrugated plate infills is investigated in this study. Finite element (FE) analysis was adopted using ANSYS software, wherein flat an

2. Behavior of Damaged Exterior RC Beam-Column Joints Strengthened by CFRP Composites
Abstract This paper presents an experimental investigation on the behavior of retrofitted beam-column joints subjected to reversed cyclic loading. The experimental program comprises 8 external beam-column joint connection subassemblages tested in 2 phases; one was the damaging phase and second was the repairing phase. The Beam-column joints were designed onl

3. Displacement ductility for seismic design of RC walls for low-rise housing
The paper compares and discusses displacement ductility ratios of reinforced concrete walls typically used in one- and two-story houses. Ductility is investigated by assessing response measured on 39 walls tested under shaking table excitations and quasi-static lateral loads. Variables studied were the height-to-length ratio and walls with openings, type of

4. DYNAMIC BEHAVIOR OF BURIED PIPES: METHODOLOGY AND COMPUTATIONAL IMPLEMENTATION / COMPORTAMENTO DINÂMICO DE DUTOS ENTERRADOS: METODOLOGIA E IMPLEMENTAÇÃO COMPUTACIONAL
This work presents a numerical methodology for the analysis of buried pipes employed by the transport of oil and gas subject to dynamic loads. Emphasis is given to seismic loads. A finite element model based on a special class of beam element for the pipe representation is employed. Both geometric and material nonlinearities are considered in a total Lagrang

5. Controle de vibrações em edifícios submetidos à ação de cargas dinâmicas utilizando amortecedor de massa sintonizando na forma de pêndulo / Vibration control of structures subjected to dynamic loads using tuned pendulum-shaped mass dampers
The ongoing progress of structural analyses and dimensioning, in addition to the continuous advancements in building techniques and material, has made it possible to build taller and more slender structures every day. These structures are also more vulnerable to excessive vibrations caused by dynamic loads like earthquakes, winds, waves, intense traffic, and

6. ANÁLISE NUMÉRICA DO ALTEAMENTO DE BARRAGENS DE TERRA / NUMERICAL ANALYSIS OF RAISING EARTH DAMS
One of the activities related to dam constructions involves the raising of the existent structure, normally done with the objective of increasing the water storage capacity of the reservoirs, improving the safety factor of the embankment slopes or to ensure a better protection against possible water flooding. The raising of an earth dam can be predicted in t

7. 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

8. EXPERIMENTAL ANALYSIS OF THE DYNAMIC PROPERTIES OF THE BAMBOOS OF THE SPECIES GUADUA, DENDEDROCALAMUS E AUREA / ANÁLISE EXPERIMENTAL DAS PROPRIEDADES DINÂMICAS DOS BAMBUS DAS ESPÉCIES GUADUA, DENDROCALAMUS E AUREA
The Bamboo is classidied as Bambusoideae or as Bambusaeceae that can be fond in abundance in tropical and sub-tropical contries. Studies had shown that the relation tensile stregth and specific weight of the bamboo is 2.73 greater that of the steel with the advantage to have a low consumption of energy and low cost in its production, besides being a renewabl
