1. Numerical analysis of reinforced concrete asymmetric cross-section beams under oblique bending
Abstract The problem of symmetric cross-section beams under oblique bending is well known to professional designers and academy. In fact, symmetric elements make up most of the cross-sections defined in design. The case of the asymmetric cross-sections is, however, little discussed in literature, but is a particular problem, especially in bridge girder desig

2. 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

3. Study of pedestrian-induced vibrations on timber footbridges / Estudo das vibrações induzidas por pedestres em passarelas de madeira
No Brasil, o estudo a respeito das vibrações induzidas por pedestres em passarelas vem sendo realizado a partir do início dos anos 1990, para passarelas de concreto e de aço. No entanto, ainda não há registro de estudos desse tipo e a norma brasileira NBR 7190 (1997) de projeto de estruturas de madeira apresenta somente critérios de dimensionamento pa

4. 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

5. Vibration analysis of orthotropic composite floors for human rhythmic activities
Competitive world market trends have long been forcing structural engineers to develop minimum weight and labour cost solutions. A direct consequence of this design philosophy is a considerable increase in problems related to unwanted floor vibrations. This phenomenon is very frequent in a wide range of structures subjected to dynamical loads. The main objec

6. RELIABILITY-BASED DESIGN OPTIMIZATION OF REINFORCED CONCRETE PLANE FRAMES / PROJETO ÓTIMO BASEADO EM CONFIABILIDADE DE PÓRTICOS PLANOS DE CONCRETO ARMADO
This work compares the Deterministic Design Optimization (DDO) with the Reliability-Based Design Optimization (RBDO) of reinforced concrete plane frames. The structure is modeled by a finite element mesh using bar elements and considering both geometric and material nonlinearities. In the formulation of the proposed optimization problem the design variables

7. Development of truck weight limits for concrete bridges using reliability theory / Aplicação da teoria da confiabilidade na obtenção de limites para o peso de veículos de carga em pontes de concreto
The increase in gross weight limits allowed by Brazilian legislation and the appearance of new truck configurations in last years require the assessment of bridges structural safety when submitted to real traffic. This thesis verifies the performance of the bridges under DER-SP jurisdiction using the reliability index beta and obtains truck weight limits in

8. Projeto e construção de lajes nervuradas de concreto armado. / Design and construction of reinforced concrete ribbed slabs.
The demand for simple and efficient solutions is increasing in civil construction, wherein the reduction of costs and the increase of speed and versatility within the applications are required. Due to its advantages, reinforced concrete ribbed slabs have been consolidated as an excellent alternative to compose buildings floors. The present research deals wit
