A Study on the Strength of Shear Connectors in Composite Beams of Steel and Lightweight Concrete Slabs with Deck Plate |
| Abstract |
The strength of shear connectors embedded in lightweight concrete slab with deck plate is influenced by various factors of deck plate, shear connector and concrete.Generally, it is reported that the strength of shear connector in lightweight concrete decreases in comparison with that in normal concrete.So this paper is to use compressive strength of lightweight concrete, width-height ratio of deck plate, and cross sectional area of shear connector as variables, to evaluate the strength of shear connectors in composite beam of steel and lightweight concrete slabs with deck plate, and then to suggest the reasonable strength equation by comparing the Push-out test results with established strength formula. As the result of 24 specimens test, in case of lightweight concrete slab with deck plate, it has showed that in the same strength, the strength of shear connector decreased about 10-20% in comparison with that in normal concrete. In spite of lightweight concrete, the test results were closely approached the established strength formula of shear connector using Fisher's reduction coefficient. |
