3. Finite element analysis of high modal dynamic responses of a composite floor subjected to human motion under passive live load
Light weight and long span composite floors are common place in modern construction. A critical consequence of this application is undesired vibration which may cause excessive discomfort to occupants. This work investigates the composite floor vibration behavior of an existing building based on a comprehensive study of high modal dynamic responses, the rang

4. Transverse load distribution of skew cast-in-place concrete multicell box - girder bridges subjected to traffic condition
Concrete multicell box-girder bridges are a common choice among the designers for various ranges of bridges. In order to provide safer and greater speed of traffic, the roadway is built as straight as possible. The use of skewed bridges has increased considerably in the recent years for roadway. The skewed bridges have quite different mechanical behavior fro

5. Contribuição ao estudo da estabilidade de edifícios de andares múltiplos em aço / Contribution to the study of stability of steel multi-storey buildings
This work presents a comparative analysis of different structural systems for a 20-storey building. Each model has been designed using the principles of the direct analysis method (DAM), present in the ABNT NBR 8800:2008. The first-order amplification method (FOAM) was used to obtain, in a simplified manner, the forces acting on the building elements, includ

6. Aplicação de redes inteligentes nas instalações elétricas residenciais / Application of smart grid in residential electrical installations.
Electricity as an energy resource acquired vital importance in modern society because it allows relatively easily meet the demand for their services. Thus the demand for electricity increases with the evolution of populations who benefit from. The electrical system that produces this input is limited in its ability to available resources for generation, tran

7. Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) and for four full-scale beam bending tests. The accuracy of analytical design equations is evaluated by comparing their predictions with e

8. Reliability analysis of I-section steel columns designed according to new Brazilian building codes
This paper presents an evaluation of the safety of I-section steel columns designed according to the new revision of the Brazilian code for design of steel buildings (NBR8800) and to the code for loads and safety of structures (NBR8681). The safety evaluation is based on structural reliability analysis of columns designed to comply with these codes, and on a

Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental
The generation of industrial waste has been the object of increasing attention in the field of Science and Technology because of the problems which arise when it is stored and inadequately disposed of. This can have negative consequences for the worker, the company and for the neighboring population. In addition it can generate liabilities for the environmen

11. Estudo do impacto de veículos pesados sobre a infra-estrutura rodoviária através de simulação microscópica de tráfego / Study of heavy vehicles impact on highway infra-structure through microscopic traffic simulation
The objective of this research was to develop a method for establishing the effect of heavy vehicles characteristics and operation on highway infra-structure by using the results of a microscopic traffic simulation model. Therefore, two secondary objectives were defined. The first of them involved the attainment of a detailed database containing the characte

12. Utilização do sensoriamento remoto na avaliação das características limnológicas do reservatório de Itaparica, no sub-médio rio São Francisco
The land inhabitants generally cause environmental impact on the marginal areas where they live in. For this reason, the evaluation of limnologic data of water bodies through remote sensing can bring information on environment aspects in a synoptic and periodic fashion. Taking into account this fact, the work aimed to study the limnologic characteristics of
