Resistance Performance

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.

Rapid Deformation

For a floor of a building with no less than four stories and no more than twelve stories, the two-hour fire resistance performance should be satisfied. In the case of slabs with steel studs, no two-hour fire resistance performance has been proposed in Korea. In this study, the two-hour fire resistance performance of slabs with steel studs performing as structural elements of modular buildings was evaluated. These specimens were redesigned based on the typical slab used in Europe and North America by modifying the 45 mm fire-resistant board to achieve two-hour fire resistance. The experimental results showed that the FR-001 specimens with 140 mm mineral wool applied to the lower slab and the FR-002 specimens containing 100 mm lower-slab glass wool and 150 mm upper-slab mineral wool did not satisfy the two-hour fire resistance performance, owing to the rapid deformation of the specimens after 75 and 110 min, respectively. However, the FR-003 specimens containing 100 mm glass wool, 150 mm mineral wool in the upper slab, and concrete in the slab satisfied the two-hour fire resistance performance requirement.
