1. Phosphorus dynamics in a highly polluted urban drainage channel-shallow reservoir system in the Brazilian semiarid
Abstract: This paper investigates phosphorus dynamics in a highly polluted system composed of a drainage channel followed by a shallow reservoir in the city of Fortaleza, Brazilian semiarid. During the dry season, significant non-point source loads of total phosphorus originated from residences unconnected to sewers were identified along the channel, resulti

2. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

3. Dynamic analysis of a concrete chimney considering the aerodynamic damping
Resumo Tradicionalmente, estruturas submetidas ao vento são avaliadas através de análises estáticas com carregamentos equivalentes, onde a influência da resposta flutuante é levada em conta por meio do fator de rajada. Essa metodologia é aplicável a estruturas suficientemente rígidas para não apresentarem resposta dinâmica ponderável [ ]. Estrutu

4. Experimental study of the neighborhood effects on the mean wind loading over two equivalent high-rise buildings
Abstract This paper presents a series of results with respect to the mean values of shear, base moment and torsion acting in a building obtained through an experimental wind tunnel study using the standard building proposed by the Commonwealth Advisory Aeronautical Research Council (CAARC) as building reference. In the loading determination, the interferenc

5. Contribuição ao estudo da estabilidade de edifícios de andares múltiplos em aço / Contribution to the study of stability of steel multi-storey buildings
This work presents a comparative analysis of different structural systems for a 20-storey building. Each model has been designed using the principles of the direct analysis method (DAM), present in the ABNT NBR 8800:2008. The first-order amplification method (FOAM) was used to obtain, in a simplified manner, the forces acting on the building elements, includ

6. Characterization of Surface Level Wind in the Centro de Lançamento de Alcântara for Use in Rocket Structure Loading and Dispersion Studies
Abstract: We present wind data collected for ten days during the dry season in 2008 during the Murici II Campaign, which was carried out in the area of the Centro de Lançamento de Alcântara (CLA). The main goals are to better understand processes governing the wind regime in the CLA and the development of tools for analyzing the impact of wind on rocket st

7. Aeroelastic modeling and experimental analysis of a flexible wing for wind tunnel flutter test.
The objective of this work is to investigate the flutter phenomena experimentally, which will unify high aspect ratio wings design for wind tunnel flutter tests (Dowell and Tang, 2002), cheaper aeroelastic models construction and a procedure used by Sheta, Harrand, Thompson and Strganac (2002) to identify the flutter onset power spectral density versus the f

9. Análise numérica do comportamento estrutural e da resistência de terças de aço restringidas pelas telhas / Numerical analysis of cold-formed purlin-sheeting systems focused on the structural behavior and strength
The structural behavior of purlin-sheeting system is complex and the complete analysis should consider the physical and geometrical nonlinearity, as well as the influence of the purlin-sheeting contact and connection. The brazilian code NBR 14762:2001 provides a design procedure to consider the interaction between a purlin or girt connected to the sheeting (

10. Adaptive techniques applied to offshore dynamic positioning systems
Dynamic positioning systems (DPS) comprise the deployment of active propulsion to maintain the position and heading of a vessel. Several sensors are used to measure the actual position of the floating body, while a control algorithm is responsible for the calculation of forces to be delivered by each propeller, in order to counteract all environmental forces

12. Structural Analysis of Transmission Line Steel Towers Subjected to Wind Induced Dynamic Effects / Análise estrutural de torres de transmissão de energia submetidas aos efeitos dinâmicos induzidos pelo vento
Na prática corrente do projeto de torres de aço treliçadas utilizadas para suportar linhas de transmissão de energia elétrica, a avaliação do comportamento dinâmico das estruturas, de maneira geral, não é considerada. Contudo, o principal carregamento a ser considerado na análise estrutural das torres de transmissão de energia elétrica é produz
