1. Study of the interaction of concrete walls with the foundation structure
Abstract This article presents a study of the factors that influence the mechanism of soil-structure interaction with a pilot building having concrete walls and their impact on their performance. To illustrate the studies carried out, a numerical modeling of a four-floor concrete wall pilot building was performed, subjected to vertical actions, supported by

2. Optimized dimensioning of steel-concrete composite beams
Resumo As seções mistas de aço e concreto estão cada vez mais sendo utilizadas na construção civil, tanto no cenário mundial quanto no Brasil. O trabalho conjunto do perfil de aço e da laje de concreto aumenta consideravelmente o desempenho do elemento estrutural misto devido ao aproveitamento das vantagens de cada material. Neste trabalho, é utiliz

3. About the use of semi-continuity in simply supported composite steel and concrete beams, to remove fireproof coatings for standard-fire resistance requirement of less than 30 minutes
Resumo Estudos anteriores do comportamento sob ação do incêndio de vigas mistas de aço e concreto, sem instabilidades locais (ditas compactas), considerando a rigidez à flexão nos apoios fornecida pela armadura negativa longitudinal à viga (semicontinuidade), mostraram que não é possível justificar a ausência de revestimento contra fogo para tempo

4. Evaluation of the resistance of trussed slabs with steel formwork in cold formed U profile
Abstract In the last decades, the modernization in structural engineering has increased the use of steel-concrete composite and hybrid systems for slabs, when the adherence in the interface of the materials is present or not, respectively. In addition to the traditional steel deck, a similar solution for precast trussed slabs has been used for small construc

5. 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

6. Shear strength analysis of slabs without transverse reinforcement under concentrated loads according to ABNT NBR 6118:2014
Resumo A solicitação por cargas parcialmente distribuídas em lajes sem armadura transversal, frequente em tabuleiros de pontes, resulta na propagação horizontal da força cortante em direção aos apoios, situação na qual nem toda a largura da laje é mobilizada. Por esta razão, os modelos de resistência à força cortante de vigas e de resistência

7. Behavior of expanded polystyrene as lightweight filler in retaining walls with intermediate slabs
Abstract The present study explores a retaining wall with an intermediate slab. To reduce the lateral earth pressure on the wall, the substitution of part of the soil by blocks of expanded polystyrene (EPS) with high density is proposed, which could result in significant economic savings. Also, the possibility of building the wall elevation with smaller thic

8. 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

9. Fracture Failure of Reinforced Concrete Slabs Subjected to Blast Loading Using the Combined Finite-Discrete Element Method
Abstract Numerical modeling of fracture failure is challenging due to various issues in the constitutive law and the transition of continuum to discrete bodies. Therefore, this study presents the application of the combined finite-discrete element method to investigate the fracture failure of reinforced concrete slabs subjected to blast loading. In numerical

10. Computational Modelling of RC Slabs Cracking with an Embedded Discontinuity Formulation
Abstract This paper investigates the cracking process of reinforced concrete slabs subjected to vertical load, involving their crack pattern and the load-displacement capacity curve. Concrete was discretized with hexahedral finite elements with embedded discontinuities; whereas steel reinforcement was represented by 3D bar elements, placed along the edges of

11. 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,

12. 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
