15. 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

18. Numerical-experimental analysis of concrete structures using the fracture energy / Análise numérico-experimental de estruturas de concreto com utilização da energia de fraturamento
The evolution of the concrete mixes used during the last decades gave birth to the High Performance Concrete (HPC), which, among its main characteristics, presents high strength and low permeability. With the development of chemical products used in civil engineering constructions, mainly the superplasticizers, the use of this kind of concrete has become mor

19. UMA FORMULAÇÃO DE ELEMENTOS FINITOS AXISSIMÉTRICOS PARA ANÁLISE DE TUBOS LAMINADOS EM MATERIAIS COMPÓSITOS / AN AXISYMMETRIC FINITE ELEMENT FORMULATION FOR THE ANALYSIS OF LAMINATED COMPOSITE TUBES
The use of composite materials in structures has grown in the engineering practice due to its characteristics, of high strength, low density and a good stability to thermal effects. A class of composites, the fibrous laminates, is generally used in tubes subjected to many types of loadings as internal and/or external pressure, traction, torsion, temperatures

22. Aspectos sinóticos associados à ocorrência do jato em baixos níveis na América do Sul - reanálise NCEP/NCAR e simulação com o MCGA CPTEC/COLA / Synoptics aspects associated to the occurrence of the low levels jet in the south America - reanalyses of the NCEP/NCAR and simulation with the MCGA CPTEC/COLA
Cases of LLJ occurrence to the east of Andes were identified in NCEP/NCAR reanalyses data and in daily results of a climate simulation with the CPTEC/COLA AGCM, to identify the associated atmospheric patterns. weather forecasting of a case when there was occurrence of LLJ was also evaluated. Analysis performed in different seasons indicated similar synoptic
