13. Failure behavior modeling of slender reinforced concrete columns subjected to eccentric load
AbstractThis work presents a numerical model to simulate the failure behavior of slender reinforced concrete columns subjected to eccentric compression loads. Due to the significant influence of the lateral displacements on the loading state provided by an eccentric load, geometric nonlinearity is considered. The responses of the concrete in tension and comp

14. A numerical study on seismic response of self-centring precast segmental columns at different post-tensioning forces
Precast bridge columns have shown increasing demand over the past few years due to the advantages of such columns when compared against conventional bridge columns, particularly due to the fact that precast bridge columns can be constructed off site and erected in a short period of time. The present study analytically investigates the behaviour of self-centr

15. Two and three-dimensional morphometric analysis of trabecular bone using X-ray microtomography (µCT)
INTRODUCTION: Trabecular bones have a porous microstructure and can be modeled as linear elastic solids, heterogeneous and anisotropic. In the literature, few investigations have compared the two- dimensional (2D) and three-dimensional (3D) morphometric analyses of cancellous bone. METHODS: In this investigation eighteen cylindrical samples of cancellous bon

16. Dynamic responses and damages of water-filled cylindrical shell subjected to explosion impact laterally
An account is given of some principal observations made from a series of experiments in which metal cylindrical shells were subjected to lateral explosion impact by different TNT charge mass and stand-off distance. These cylindrical shells were filled with water in order to identify the main effects produced by the fluid-structure interaction. In comparison,

17. Análise mecânica e fotoelástica de sistemas de fixação interna estável utilizados para o tratamento de fraturas subcondilares da mandíbula / Mechanical and photoelastic analysis of internal fixation systems used for treatment of subcondylar mandibular fractures
Fractures of the mandibular condyle are presented as the most common injuries to the maxillo-mandibular complex, however there is still great controversy regarding treatment. The aim of this study was to assess comparatively, in vitro, by mechanical and photoelastic testing, fixation for condylar fractures with different systems. For the mechanical tests 60

18. In-situ quasi-static and dynamic behavioural response of steel tubular frames subjected to lateral impact loads
Steel tubular members are widely used as primary and secondary structural framing members in offshore oil and gas platforms. A platform is inherently liable to collisions from ships which can create severe structural damages in the rig. The effect of this damage has been studied by a number of researchers through investigating the impact behaviour isolated t

19. Provas de cargas estáticas instrumentadas em profundidade em estacas escavadas de grande diâmetro (Estações). / Static loading tests instrumented in large diameter drilled piles.
Objetivou-se estudar o comportamento de estacas escavadas de grande diâmetro em uma obra de um Shopping Center na cidade de São Paulo. As estacas foram submetidas a carregamentos axiais de compressão, sendo que as estacas foram instrumentadas em profundidade. Utilizou-se de teorias amplamente conhecidas no meio técnico com o propósito de interpretar as

20. Comportamento de estacas escavadas de pequeno diâmetro em solo laterítico e colapsível da região de Campinas/SP / Behavior of bored piles of small diameter in collapsible and lateritic soil in the region of Campinas/SP
This paper aims to study the behavior of bored piles of small diameters, subjected to axial compression loads by static load tests carried out at the Field of Experimental Soil Mechanics and Foundation 2 at Unicamp. The CEMSF2 has a geological profile whose first layer is composed of silty clay, with coluvionar, lateritic, and collapsible features.This study

22. 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

23. A boundary element analysis on the influence of Krc and e/d on the performance of cyclically loaded single pile in clay
The environment prevalent in oceans necessitates the piles supporting offshore structures to be designed against lateral cyclic loading initiated by wave action. Such quasi-static load reversal induces deterioration in the strength and stiffness of the soil-pile system, introducing progressive reduction in the bearing capacity associated with increased settl

24. Response of vertical pile group subjected to horizontal cyclic load in soft clay
The environment prevalent in ocean necessitates the piles supporting offshore structures to be designed against lateral cyclic loading initiated by wave action. Such quasi-static load reversal induces deterioration in the strength and stiffness of the soil-pile system introducing progressive reduction in the bearing capacity as well as the pile head displace
