1. Seismic resistance performance of a utility tunnel in saline soil foundation based on new cementitious composite materials
Abstract Because soluble salt in saline soil dissolves with water, utility tunnels built in saline soil foundation are more likely to damage due to by groundwater and earthquake. In this study, new cementitious composite materials were developed by using slag, building gypsum, quicklime, and magnesia. The unconfined compressive strengths of the saline soil s

2. Migração haitiana: o sujeito frente ao (re)encontro com o excesso
Resumo Este artigo retrata uma pesquisa qualitativa a respeito do movimento migratório de sujeitos haitianos. Aborda-se a existência e/ou a fragilidade dos recursos de enfrentamento por parte do migrante, considerando-se que as condições do país de destino acabam, por vezes, reeditando o desamparo experimentado no país de origem. Participaram deste est

3. Nonlinear static analysis of a pile-supported wharf
Resumo O objetivo deste artigo é desenvolver uma análise estática não-linear através de um estudo de caso de um cais sobre estacas situado em uma nova área portuária para petroleiras. A atividade sísmica da área é muito intensa com uma aceleração máxima do solo de 0.55 g. Por esta razão, é muito importante analisar o comportamento estrutural n

4. Effects of soil-structure interaction in seismic analysis of buildings with multiple pressurized tuned liquid column dampers
Abstract In this paper soil-structure interaction (SSI) effects are investigated while an array of Pressurized Tuned Liquid Column Dampers (PTLCD) is employed for seismic vibration control of buildings. This device represents the most general case of a passive damper, with different reduction options to other control devices obtained by simplifying the invol

5. EXPERIMENTAL INVESTIGATION ON CONCRETE FILLED STEEL TUBULAR COLUMN TO FOUNDATION CONNECTIONS SUBJECTED TO COMBINED AXIAL AND LATERAL CYCLIC LOADING
Abstract This study focuses on performance of CFT column to foundation connections subjected to combined axial and lateral cyclic loading. Experimental investigations were carried out on five specimens with exposed column base and embedded column base connections. The parameters considered were number of stiffeners and embedment depth of CFT column. The forc

6. "A DIFICULDADE NÃO É FALAR, MAS LER FREUD EM PORTUGUÊS": UM OLHAR PARA AS PRÁTICAS DE LETRAMENTO NA EDUCAÇÃO SUPERIOR DE ESTUDANTES HAITIANOS NO BRASIL
RESUMO Após o terremoto de 2010 que afetou a capital do Haiti, Porto Príncipe, o Brasil começou a receber progressivamente um número significativo de imigrantes do país caribenho. O foco da presente pesquisa é um grupo de estudantes haitianos que chegou ao Brasil, em 2011, por meio de um programa de cooperação que tinha, como um de seus objetivos, pe

7. O GRANDE TERREMOTO DE LISBOA E A IRRUPÇÃO DE UMA NOVA ORDEM SOCIOEDUCATIVA
RESUMO O presente artigo, lastreado por algumas noções teóricas legadas por Michel Foucault, devota-se a descrever e analisar a emergência de uma nova ordem socioeducativa em Portugal após o terremoto de 1775, responsável pela reconfiguração do nexo poder-saber-verdade que havia pautado os modos de existência até então. A argumentação mobiliza u

8. Numerical Study of the Circumferential Fuses Used in Steel Repairable Buildings with Seesaw Motion
Abstract Structural fuses and rocking system are used in order to reduce the building response to earthquakes and damage guidance. In the proposed seesaw motion system, which is similar to the rocking system, the building columns, in top of the foundation, have been removed and a central support and structural fuses are used around the building instead of th

10. Three-level performance-based optimization method of steel frames
Abstract This paper describes a three-level performance-based optimization model and an estimate method of residual top displacement for steel frames at three earthquake levels. The steel frames are supposed to be elastic at frequent earthquake, inelastic and hardening at occasional and rare earthquakes, respectively. The estimate formula is derived and est

11. Modelling of Rocking and Sliding Effects in the Seismic Analysis of a Free-Standing Column
Abstract A study on the seismic response of a free-standing marble column, including rocking and sliding effects, is presented in this paper. The rocking-sliding model implemented for the development of the analyses corresponds to the basic theoretical and numerical simulation of the dynamic phenomenon. The assessment procedure adopted for the application of

12. Optimization of location and forces of friction dampers
Abstract Damper optimization is a new area which has been investigated in recent years. There are various methods employed in optimization, among which are highlighted the classic and the most recent that are functioning with reliability, efficiency and speed for optimum results. This paper proposes a method for simultaneous optimization of placement and for
