1. THE TOPPLING OF AN IRRIGATION CENTER PIVOT SUBMITTED TO WIND ACTION EFFECTS
ABSTRACT This research aims to improve the study about the stability of truss structures used in pivot irrigation, widely used due to the growing demand for food production, when submitted to wind effects. Specifically, it aims to verify the maximum wind speed supported by an irrigation center pivot structure when submitted to the load effects caused by wind

2. Comparative study of tall building response to synoptic and non-synoptic wind action
Abstract Until the beginning of the 21st Century, the characteristics of wind for purposes of structural analysis and design, as reflected in wind codes worldwide, were based on the behavior of wind currents in the vicinity of the ground surface observed in so-called synoptic events. It was only recently recognized that the latter are not the only cause of w

3. Simulação experimental da interação vento-chuva / Experimental simulation of the wind-rain interaction
Simultaneous occurrences of the combined action of rain and wind in different types of structures have been observed around of the world in the last 20 years. This mechanism has been causing curiosity to engineers and researchers due to their jeopardizing consequences to constructions. In these last twenty years people has been seeking for a way to simulate,

4. A new approach in the use of computational tools in teaching content of the discipline "Concrete Structures" in the Civil Engineering courses / Uma nova abordagem na utilização de ferramentas computacionais no ensino de conteúdos da disciplina estruturas de concreto em cursos de Engenharia Civil
This presentation analyzes the two computational tools, GPLAN (Plan Grills) and FTOOL (Two-Dimensional Frame Analysis Tool), and how they can be used in the content of "Concrete Structures" discipline, in Civil Engineering Graduation. The considered study is divided in two topics, being the first, the plan grills consideration (interaction plate/ beam) in th

5. Avaliação das propriedades de transporte de massa contendo adições minerais / Evaluation of the mass transport containing mineral admixtures
The durability of reinforced concrete structures is damaged by the degrading action of the penetration of substances in the form of gases, vapors and liquids through the pores and cracks. It is known that water both in its pure form or containing dissolved ions such as chloride, sulphate, carbon dioxide or oxygen ions, can compromise the durability of concre

6. Uma avaliação experimental e numérica do efeito da rigidez geométrica na resposta dinâmica de estruturas esbeltas sujeitas à excitação de vento. / An experimental and numerical evaluation of the geometric stiffness effect on the dynamic response of slender structures under wind excitation.
Due to a politically and economically pragmatic decision, Brazil has chosen to intensely develop its cellular phone system, in order to bypass a stage of development. Once the decision has been taken, implementation was set in an explosive pace in the 1990s decade by installing tens of thousands of stations. As the electronic systems are usually more expensi

7. Structural behavior of tower stell to support a wind turbine / Comportamento estrutural de torres de aço para suporte de turbinas eólicas
The increasing demand for electricity required by individual and industrial consumers brings back the issues related to the exhaustion of the exiting fossil energy sources and leads to the evident needs for investments in research topics that focus on improving, developing available renew able energy sources or even creating some novel energy renewable alter

8. Análise teórico-experimental da conexão estampada de treliça espacial de aço sob carregamentos estático e cíclico
Three-dimensional structures made of steel bars, widely known as space trusses, are very frequently used at the construction of roofs. These structures consist of steel bars, generally, connected by bolts at nodes. There are several types of connection for these 3D trusses, many are patented but others are not. In Brazil, the connection usually employed in t

9. Uma metodologia para anÃlise das conseqÃÃncias de um blowout durante a perfuraÃÃo de poÃos offshore / A methodology for analysis of the consequences of one blowout during the perforation of wells offshore
The main safety concern during the drilling of oil wells is the possibility of blowout. A blowout is the release of hydrocarbons under pressure. In case that the immediate ignition of these hydrocarbons occurs, the expected fire is a jet fire. Jet fire are turbulent diffusion flames. Normally, the thermal energy released for the jet fire is very high and suf

10. Analise de estruturas metalicas de torres treliçadas autoportantes para telecomunicações
This work presents a comparative analysis of static and dynamics actions that affect predominantly the latticed self supporting metallic towers for telecommunications. Theoretical foundations concerning to linear dynamic analysis are presented, which are used in the development of formulations presented in the Brazilian standard code NBR 6123/87 to obtain th
