1. Reliability and geotechnical safety applied to deep foundations in precast concrete piles - case study
Abstract The Brazilian standard pertinent to the design and execution of foundations, NBR 6122/2019, establishes that the safety inspection of foundations of a given project must be conducted based on compliance with specified safety factors. Safety factor verification is imperative to meet regulatory requirements; however, it is not enough to guarantee the

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. Avaliação do comportamento solo-estrutura de elementos de fundação tipo sapata estaqueada / Assessment of the behavior of soil-structure foundation elements like piled footing
This work aims to study the behavior and interaction between soil, shallow footing and pile, based on the implementation and monitoring of four direct load tests performed on: a single shallow footing, a shallow footing with one pile, a shallow footing with four piles and a pile alone. During the load tests, vertical displacements were monitored at different

4. Estudo do jateamento em solos argilosos e sua aplicação à engenharia de fundações offshore / Study of water jets in clay and its application to offshore foundation engineering design
Most of all petroleum produced in Brazil is encountered in marine deposits where the water depth may exceed 1000 meters. Recent discoveries of new offshore oil fields have motivated studies in this area designed to develop new techniques applied to oil exploration. For the extraction of oil deposits floating platforms are commonly used, supported by anchorag

5. 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

6. Aplicação da técnica da fotoelasticidade na análise de fundações por estacas helicoidais / Aplication of the photoelastic method to the analysis of helical screw pile foundations
A técnica da fotoelasticidade pode ser particularmente útil na análise de tensões em sistemas com geometrias complexas. Em um equipamento chamado polariscópio, um feixe de luz polarizada atravessa o modelo fotoelástico que representa o protótipo. Ao submeter este modelo a um carregamento, faixas de diferentes cores poderão ser visualizadas. Cada cor

7. Análise do comportamento de blocos sobre quatro estacas com cálice embutido / Analysis of the behavior of four-pile caps with embedded socket
A racionalização e a industrialização da construção civil têm promovido o sistema construtivo baseado em elementos de concretos pré-moldados. O comportamento das ligações entre os elementos pré-moldados constitui uma das principais preocupações dos projetistas, sendo as ligações entre a superestrutura e as fundações determinantes na estabili

8. DeterminaÃÃo do coeficiente de transferÃncia de cargas nas fundaÃÃes de silos verticais cilÃndricos de base semi-V
Engineering structures are designed according to the imposed stress. In the case of silos, there is not a Brazilian standard regulation to prescribe their projects and actions. This limitation leads designers to use the foreign standards requirements which, however, differ from one another. This paper shows the evolution of knowledge about the subject, and a
