1. On the use of parameter γ z in fire situation
Resumo A seguir será apresentado um estudo sobre o uso do parâmetro γz em pórticos de concreto armado em situação de incêndio. Atualmente, não se têm resultados de investigação similar em estruturas de concreto, já que o tema não tem recebido atenção adequada. Em situação de incêndio muitas das ações horizontais deixam de ser consideradas

2. Efeito da adição de resíduo de vidro em massa de cerâmica de alvenaria
RESUMO Este trabalho investigou o efeito da adição de resíduo de vidro para fabricação de cerâmica de alvenaria. Foram conformados corpos-de-prova cilíndricos de 27 mm de diâmetro por 45 mm de altura, a partir da massa padrão de uma indústria de cerâmica vermelha e outras 3 formulações (5, 10 e 20%) com incorporação de vidro, baseado em estudo

3. Temperature field of concrete-filled steel tubular columns in fire
Abstract The composite structures formed by the association of steel profiles with concrete have shown to be an advantageous alternative, improving the behavior of the steel structures concerning their load capacity, stiffness, and durability, under fire conditions. The concrete-filled tubular columns have become an attractive alternative for the civil const

4. Fire response of a 3D multi-storey building with buckling restrained braces
Abstract This paper investigates the performance of a three-dimensional multi-storey structure with Buckling Restrained Brace system (BRBs) under fire condition, using a sequentially coupled nonlinear thermal stress analysis. Efficiency of using BRBs in enhancing the strength and stiffness of a structural frame is compared with that of Ordinary Concentricall

5. Fire Resistant Aircraft Unit Load Devices and Fire Containment Covers: A New Development in the Global Air Cargo Industry
ABSTRACT: Unit load devices (ULDs) are pallets and containers which are used to carry air cargo, mail and passenger baggage on wide-body aircraft. This paper analyses two important recent developments in the suppression of fires on freighter aircraft - fire resistant containers and fire containment covers for palletised cargo. In July 2013, United Parcel Ser

6. Estoque de combustível fino e decomposição de folhas em florestas de igapó do rio Negro / Fine fuel load and leaf decomposition in Rio Negro floodplain forests
In years of low rainfall, fires have occurred in Amazonian black-water floodplain forests, including the Middle Rio Negro. The fires are documented from satellite images. Forest fires require ignition sources, fuel and dry weather. To understand the susceptibility of these forests to fire we investigated the stock of fine fuel on the ground at 29 sites in bl

7. Pilares de concreto armado em situação de incêndio submetidos à flexão normal composta. / Reinforced concrete columns in fire under uniaxial bending.
According to Brazilian Codes, reinforced concrete structures must be verified under high temperatures, in order to assure the load bearing capacity to allow the safe evacuation of the users and the fire fighting and to reduce the fire spread to other compartments. For reinforced concrete structures, the columns must be analyzed carefully. The significant red

8. An investigation on graphene and nanoclay effects on hybrid nanocomposites post fire dynamic behavior
This paper deals with the post fire behavior of hybrid nanocomposites under dynamic loadings. A series of tests were performed to investigate how nanoparticles (i.e. nanoclay and graphene nanosheets) affect the post-fire overall composite behavior. Carbon fiber/epoxy-nanoclay and carbon fiber/epoxy-graphene nanosheets were manufactured. The nanoparticles emp

9. Colunas mistas esbeltas de aço preenchidas com concreto de alta resistencia em temperatura ambiente e em situação de incendio / Mixed slender steel columns filled with high strenght concrete in room temperature and fire situation
In this work, it was investigated in laboratory the effect of fire in slender steel columns unfilled and filled with high strength concrete submitted to three different levels of axial load (30%, 50% and 70%), which is the relation between the axial load to be applied in fire situation and the ultimate load obtained in the column test to room temperature. So

10. Coupled thermal and structural analysis of steel columns under fire condition / Análise termoestrutural de pilares de aço em situação de incêndio
The most part of materials whose constitute fire protection elements or structural elements, such as steel columns, when exposed to high temperature have their strength and elasticity modulus reduced caused by thermal action. Therefore the structure can collapse earlier than in an ambient temperature situation. Based in this aspect, the objective of the pres

11. ESTUDO TEÓRICO EXPERIMENTAL DAS PROPRIEDADES DINÂMICAS DO BAMBU / THEORETICAL AND EXPERIMENTAL ANALYSIS OF DYNAMIC PROPERTIES OF BAMBOO
The studies carried on during the last three decades with respect to bamboo have been directed to the physical, mechanic and microstructural characterization of different species, under static load. The experience has shown that the houses and buildings constructed using bamboo as structural element have had good resistance to earthquakes. This work is one o

12. Desenvolvimento de um software para levantamento de características de reação ao fogo dos materiais de uso comum: carga de incêndio
The density of fire load is one of the essential parameters for modeling of fire in a building. In Brazil, the loads of fire by occupation are defined in the regulations public based on measurements made in foreign countries, customs and different climates. Measurements of local load of fire were made pioneer in Belo Horizonte and in Ouro Preto from initiati
