1. 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

2. Non-linear FEM analysis of seismic induced pounding between neighbouring multi-storey structures
Pounding of neighbouring construction of structures due to seismic excitation increases the damage of structural components or even causes collapse of structures. Among the possible building damages, earthquake induced pounding has been commonly observed in several earthquakes. Therefore it is imperative to consider pounding effect for structures. This study

3. Concreto ultraleve® estrutural com pérolas de EPS: caracterização do material e estudo de sua aplicação em lajes / Structural ultra lightweight concrete with EPS beads: material characterization and study of its use in slabs
The use of lightweight concrete is mainly due to the benefits provided by reducing the density of the material such as smaller efforts on structures, economy of molds and scaffolding, as well as lower costs of transportation and erection of precast constructions. Currently, besides the technical and economic issues, the choice of building materials should ta

4. Análise da interação placa-viga via método dos elementos de contorno / Analysis of plate-beam interaction by the Boundary Element Method
This work presents a formulation of the boundary element method for the analysis of plate-beam interaction in buildings floors. In order to properly match the beams and plate is used an alternative formulation of the boundary element method for thin plates, in which the beam is modeled by ordinary differential equations and the compatibility between plate an

5. 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

6. Lajes alveolares protendidas: cisalhamento em região fissurada por flexão / Prestressed hollow core slabs: shear in region fissured due to bending
Esta pesquisa teve como principal objetivo analisar o comportamento de lajes alveolares protendidas de uso corrente no Brasil (pequenas espessuras e alta protensão) quanto ao cisalhamento em região fissurada por ação do momento fletor, para diferentes situações: sem e com capa e com preenchimento parcial de alvéolos. Foi desenvolvido um estudo teóric

7. Análise numérico-experimental de lajes nervuradas sujeitas a cargas estáticas de serviço
Waffle slabs are, nowadays, a demand for structural designers, as a consequence of architectural design evolution and new building management concepts, in spite of its laborious numerical modeling. Therefore, it becomes necessary to know more about their structural behavior and to improve the theoretical models used for simulating these slabs. The objective

8. Análise tipológica de elementos e sistemas construtivos pré-moldados de concreto do ponto de vista de sensibilidade a vibrações em serviço / Typological analysis of precast concrete elements and building systems in terms of sensitivity to vibration in service
In the context of construction modernization, the application of precast concrete elements offers a good and reliable alternative in the construction strategy, among them large spans, fast assembly, lightweightness and excellent structural members quality. Dealing about dynamic behavior of concrete structures, precast elements are subjected to several loadin

10. 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

11. Avaliação da rigidez de pórticos tridimensionais de concreto armado / Evaluation of stiffness in three-dimensional frames of reinforced concrete
An evaluation of stiffness in three-dimensional frames is important to ensure safety in structural projects, especially in tall buildings, where both ultimate limit state and serviceability limit state have to be considered. In reinforced concrete buildings, this evaluation is calculated through an analysis of global stability, either through approximate met

12. Avaliação in loco das perdas de protensão de cordoalhas engraxadas em lajes planas
This dissertation presents the results of in situ measurements of stress losses in unbonded tendons of post tensioned flat slabs. These flats slabs have approximately 350 m2 in area and are 17 centimeter thick. They are part of a 17 story high hotel building in Belo Horizonte. Load cells were employed to measure the forces in the tendons; they were placed in
