1. Numerical formulation for nonlinear analysis of concrete and steel shells with deformable connections
Abstract A two-dimensional interface finite element capable of associating flat shell elements positioned one above the other was developed. The implemented interface element can physically simulate the contact between the flat shell elements and connect the reference planes of the shell elements above and below it. The formulation presented allows considera

2. Nonlinear numerical analysis of composite slabs with steel decking
Resumo O comportamento das lajes mistas é governado pelo cisalhamento longitudinal na interface entre o aço e o concreto, que é desenvolvido em lajes sob flexão simples. O método m-k e o método da interação parcial, utilizados no cálculo da resistência ao cisalhamento na interface aço-concreto de lajes mistas, são baseados em ensaios experimentai

3. Slabs strengthened for punching shear with post-installed steel and CFRP connectors
Resumo Acidentes estruturais por punção vêm sendo relatados em edifícios com lajes lisas. As recomendações de projeto apresentadas pelas normas podem levar a estimativas de resistência à punção divergentes para situações semelhantes. Além disso, não são apresentadas orientações para o dimensionamento do reforço à punção de lajes existent

4. Aspects of Finite Element Modeling of Punching Shear Behavior of Reinforced Concrete Flat Slabs
Abstract A series of nonlinear FE analyses was conducted in this paper to model the punching shear failure of RC flat slabs. The analyses were carried out in the software DIANA using three-dimensional continuum elements. These analyses involve the test of different modeling choices in order to evaluate their influences on punching shear failure modeling. The

5. An interface element for numerical analysis of flat plate/shell elements with deformable connection
Abstract The use of numerical methods such as the finite elements method for solving structural analysis problems is becoming ever more efficient. An interface element capable of associating flat plate/shell element in three different combinations has been developed. In a structural analysis, when only the flat plate/shell’s finite elements are used in th

6. One-Way Shear Resistance of RC Members with Unconnected Stirrups
Abstract This paper presents results of eight experimental tests carried to evaluate the mechanical performance of unconnected "W" stirrups. Reinforced concrete wide beams were tested and their characteristics were idealized to represent column strips in flat slab buildings. The main variables were: the type of shear reinforcement; the shear span to effectiv

7. NUMERICAL ANALYSIS OF THE BEHAVIOR OF FLAT SLABS PRESTRESSED CONCRETE FLOORS / ANÁLISE NUMÉRICA DO COMPORTAMENTO DE PAVIMENTOS CONSTITUÍDOS DE LAJES LISAS DE CONCRETO PROTENDIDO
Concrete flat slabs prestressed with unbounded greased strands have been used in building floors over the last years. This structural solution is ideal when the columns are regularly distributed. In addition, it is known that prestressed floors have some technical advantages when compared to the traditional solution in reinforced concrete, mainly in cases of

8. Evolução estrutural da Sierra de Umango, Sierras Pampeanas Ocidentais, Noroeste da Argentina / Structural evolution of the Sierra de Umango, Western Sierras Pampeanas, Northwestern Argentina
A Sierra de Umango está localizada na porção ocidental da Província de La Rioja, no noroeste argentino. Situa-se na região do "Pampean Flat-slab" dos Andes Centrais e conforma um conjunto de blocos do embasamento, soerguidos e rotacionados no Cenozóico, denominado de Sierras Pampeanas Ocidentais. As Sierras Pampeanas Ocidentais são caracterizadas por

9. Análise de pós-puncionamento em lajes lisas de edifícios em concreto armado
The post punching behavior of a reinforced concrete flat slab building was investigated, as consequence of punching failures resulting in partial or total residual resistance of the connections. Three buildings were analyzed using the Brazilian software TQS (13th version). The connections punching resistances were checked using Brazilian Code NBR 6118: 2003,

10. Estabilidade em edifícios de concreto armado com pavimentos em lajes planas.
This present work covers possible manners of evaluating steel concrete frames designed for multiple flooring buildings as far as instability and necessity of second order efforts are concerned. Starting from single floor projects with simple flat slab frame, models with different numbers of floors are considered. The models do not use large rigidity elements

11. Experimental nervuradas smooth flagstone analysis of reinforcement concrete with shear armor / Análise experimental de lajes lisas nervuradas de concreto armado com armadura de cisalhamento
Two-way waffle flat slabs are structural elements of reinforced concrete supported directly on columns, under bending moments over the two directions, they improve the speed of the execution and save moulds and concrete and, consequently, labor. This work seeks to contribute for the study of the behavior of this kind of slab, as the shear resistance of the r

12. Análise de lajes planas protendidas pelo método dos elementos finitos / Analysis of pre-tensioned plates by the finite element method
Na construção civil atual, existe uma tendência de crescimento da automatização do projeto, visando o desenvolvimento de soluções personalizadas a fim de fugir das indesejadas repetições arquitetônicas. Dentro desta tendência, as lajes planas protendidas proporcionam grande flexibilidade de layout, maior rapidez na execução da estrutura e diminu
