Composite beam using asymmetric H-shaped steel is one of the constructional structures developed in the advanced countries in Europe since early 1990s. The purpose of this study on composite beams where H-shaped steel is partially laid in concrete slabs was to find how to design fire protection and improve fire-resistance to make deep deck plates provide the beams with advantages upon a fire and to improve stiffness in structural aspect. Only lower flange which is directly exposed to a fire was included in fire-resistance design in order to decide optimal fire- protection design condition and test was conducted for spray-coating and paint-coating. In the fire resistance test, web thickness and lower flange thickness were varied to derive the optimum condition for improving fire-resistance performance. It was observed from the test that 90-minute-protection employed to lower flange provided fire resistance for 3 hours. It was also observed that the basic shape resisted fire for 89 minutes, while web reinforcement and lower flange reinforcement provided fire-resistance for 112 and 157 minutes, respectively. The result showed that lower flange reinforcement is the most effective way to improve fire-resistance.

Resistance Performance

Structural steel has been used since the early 1970’s in Korea as primary structural members such as columns, beams, and trusses. The materials have much higher strength such as fast construction, high load bearing capacity, high construction quality but those have a fatal weakness as well. Load-bearing capacity is going down when the structural members are contained in fire condition. Therefore, to protect the structural members made of steels from the heat energy the fire resistance performance required. Generally, the fire resistance performance have evaluated from the exact fire tests in fire furnaces. But the evaluation method takes much more time and higher expenses so, the engineering method requires. The engineering method not only adopts a science but also an engineering experience. In this paper, to make various data-bases for evaluation of structural members such as columns(H-section, RHS), beams, loaded fire tests were conducted and derived not only each limiting temperature but also fire resistance respectively.

Finite element analysis (FEA) is employed to simulate the thermo-resistance of a marine fire-proof door in the fire-resistance test defined by the International Code for the Application of Fire Test Procedures (2010 FTP Code) and required by the International Maritime Organization (IMO) for marine applications. The appropriate type of simulation adopted (i.e., steady or unsteady) is discriminated on the basis of a comparison between the numerical results and the experimental data. This appropriate model is used to evaluate the critical parameters affecting fire-proof door performance. A remarkable role of the thermal bridge at the door edges in fire resistance is assessed, along with the parameters that allow its reduction. These findings provide insight into how to design a thinner and lighter fire door.

This paper reports the investigation on the fire resistance performance of reinforced concrete column with embedded permanent formwork from woodwool board (WWCB). A series of slender column embedded with and without WWCB with cross-sections 200 mm x 200 mm for column without WWCB and 300 mm x 300 mm with embedded 50 mm thick WWCB. The height of the slender column was 2000 mm. The fire resistance test was performed in accordance with BS 476-22:1987 for two (2) hours fire exposure. The fire resistance test for the embedded column with WWCB was classified as “good” in resisting fire and heat transfer.

The structure of high-speed roller door with water film has improved in this study. The flameproof water film system is equipped with a water circulating device to reduce the water consumption of water film system. The water film is generated at the roller box of the high-speed roller door in this study. The heating test is done with the full-scale heating furnace. Both cases of the water film on unexposed surface and water film on exposed surface passed the fire resistance test based on ISO 834, proving that the high-speed roller door with water film system has 120A fire resistance period. The main findings indicate that the water film on exposed surface shows that as the amount of water film evaporated by high temperature inside the furnace must be greater than the evaporation capacity of water film on unexposed surface, the required water supply is 660 L more than the water film on unexposed surface.

Construction industries products have to satisfy fire safety regulation, including technical approvals in fire resistance, by tests in accredited laboratories. Fire resistance tests lay down on a complex protocol, in which full size samples are settled in large furnaces able to reproduce severe time-dependent fire curves. The full-scale mounting and the cost of such tests could be a constraint for their development. In that context, the concept of virtual facility has been developed by Efectis during the VIRGILE project. The use and development of numerical simulation tools are an interesting complement to the fire tests. The developed tool aims to model a fire resistance test including interaction between sample and fire test facility. The virtual facility allows to better analyze and evaluate a large number of technical alternatives in order to find the most efficient technical and economical solutions. Moreover, numerical simulations may improve the testing conditions including thermal stress control and metrology. This paper presents an overview of the main results and applications achieved during the VIRGILE project in ten years.
