説明
Current punching shear capacity equation of reinforced concrete slabs with the normal concrete excessively estimates the punching shear capacities of reinforced concrete slabs with the lightweight concrete. In this study, material tests and dowel capacity tests of using the lightweight concrete were conducted to make clear the punching shear failure condition of reinforced concrete slabs with the lightweight concrete. Dowel capacities of reinforced concrete beams using the lightweight concrete decrease due to the weakness of its aggregate in comparison with those using the normal concrete. From the test results, the predicting equation of the punching shear capacities of reinforced concrete slabs with the lightweight concrete was proposed. This equation can accurately evaluate the punching shear capacities of reinforced concrete slabs with the lightweight concrete as well as the fiber reinforced lightweight concrete. And the fatigue durability of reinforced concrete slabs with the lightweight concrete was assessed based on the existing data conducted under the wheel running machine. Furthermore, slab thickness and dead load ratios of the reinforced concrete slab with the lightweight concrete were calculated to confirm its practical use.
