13. Biomechanical analysis of the acetabular buttress-plate: are complex acetabular fractures in the quadrilateral area stable after treatment with anterior construct plate-1/3 tube buttress plate fixation?
OBJECTIVE: The acetabular buttress-plate has been widely used in treating difficult cases with satisfying clinical results. However, the biomechanical properties of a postoperative acetabular fracture fixed by the buttress-plate are not clear. The purpose of this study was to evaluate the biomechanical properties of stability after the anterior tube buttres

14. Effect of blast loading on CFRP-Retrofitted RC columns - a numerical study
This study aims to investigate the effect of blast loads generated as a result of explosive charges on the existing exterior RC circular columns of a typical building in the city of Riyadh. A procedure has been developed for evaluating the dynamic characteristics of the circular column with and without retrofitting. A wide range of parametric studies have be

15. Análise da interação solo-estrutura em edifícios sobre estacas / Analysis of soil-structure interaction in buildings on cuttings
A análise conjunta da estrutura e da fundação de uma edificação é um dos temas estudados dentro do conceito interação solo-estrutura (ISE). Neste trabalho, desenvolveu-se uma rotina de cálculo no ambiente Matlab para avaliar a interação solo-estrutura em edifícios, onde o tema é estudado há algum tempo, mas que ainda não se tornou prática cor

16. Interação solo-estrutura em edifícios com fundação profunda: método numérico e resultados observados no campo / Soil-structure interaction in buildings with deep foundation: numerical method and results observed in field
Design of concrete structures for multi-story buildings with deep foundation is considered in this work, taking in account the soil-structure interaction. This interaction is analysed with a numerical method where the superstructure (slabs, beams, and columns), and the foundation structural elements (blocks and piles) are considered a unique structure, model

18. Colunas mistas esbeltas de aço preenchidas com concreto de alta resistencia em temperatura ambiente e em situação de incendio / Mixed slender steel columns filled with high strenght concrete in room temperature and fire situation
In this work, it was investigated in laboratory the effect of fire in slender steel columns unfilled and filled with high strength concrete submitted to three different levels of axial load (30%, 50% and 70%), which is the relation between the axial load to be applied in fire situation and the ultimate load obtained in the column test to room temperature. So

19. Reliability analysis of I-section steel columns designed according to new Brazilian building codes
This paper presents an evaluation of the safety of I-section steel columns designed according to the new revision of the Brazilian code for design of steel buildings (NBR8800) and to the code for loads and safety of structures (NBR8681). The safety evaluation is based on structural reliability analysis of columns designed to comply with these codes, and on a

20. Stresses distributions of screws of the vertebral fixation systems submitted to pullout strength using plane transmission photoelasticity. / Distribuição de tensões de parafusos do sistema de fixação vertebral submetidos a arrancamento utilizando fotoelasticidade de transmissão plana
The treatment of spinal deformities, degenerative disease, injuries and tumors on the vertebral column often demand the accomplishment of the internal fixation. The pedicular screws arising enabled the accomplishment of column segmental instrumentation more stable and became a standard procedure in accomplishing surgeries of correction, deformities stabiliza

21. EXPERIMENTAL STUDY ON THE INFLUENCE OF CONCRETE COVER ON THE INTERACTION BETWEEN STEEL BARS AND CONCRETE IN ELEMENTS SUBJECTED TO COMPRESSION / ESTUDO EXPERIMENTAL DA INFLUÊNCIA DO COBRIMENTO NA INTERAÇÃO AÇO-CONCRETO EM ELEMENTOS SUJEITOS À COMPRESSÃO
The present work describes the influence of the concrete cover of the longitudinal reinforcement on the bond strength along the overlapping splice zones of compressed elements. Tests have been carried out on eighteen reinforced concrete columns, with cross section of 200 mm x 150 mm and 1100 mm of length. The longitudinal reinforcement consisted of CA-50 ste

22. Analysis of the distribution of the shear stress in the interface steel-concrete of partially encased composite columns / Analise da distribuição das tensões de cisalhamento na interface aço-concreto de pilares mistos parcialmente revestidos
The rational use of the steel and concrete in buildings, in the composition of structural sections is a economically form and structural viable, mainly in multi storey buildings. Among the vast field called "steel-concrete composite structures", we can characterize the composite columns encased like a profile of structural steel of the type "I" or "H" covere

23. Punção em lajes cogumelo : estudo da retangularidade dos pilares
Eight reinforced concrete square flat slabs of reinforced concrete were tested. Slabs were 130mm thick with an 1800 mm side and were submitted to central loading, and the objective was to investigate the influence of column rectangularity coefficient. Column cross section dimensions (cmáx/cmín) varyied between 1 and 4, with a constant perimeter equal to 10

24. VIBRATION CONTROL OF SLENDER TOWERS WITH A PENDULUM ABSORBER / ABSORSOR PENDULAR PARA CONTROLE DE VIBRAÇÕES DE TORRES ESBELTAS
In the present work the performance of a pendulum absorber in the vibration control of tall and slender towers, caused by dynamic loads, such as, environmental loads, is studied in detail. Due to the possibility of large amplitude oscillations, the non-linearity of the pendulum is considered in the modeling of the problem. The main objective of this research
