Abstract
Higher performance of High Strength Concrete (HSC) slabs attracted the engineers to provide it as floor slabs in warehouses and heavy industries. These floor slabs are subjected to higher intensities of loads including drop of objects there by subjected to dynamic effect. It has been observed that the dynamic response behaviour of slabs are obtained with a reasonable accuracy by subjecting the elements to drop test. Steel ratio in slabs plays an important role in the static and dynamic response behaviour of slabs. In the present study, HSC two-way simply supported slab strengthened with entrenched CFRP strips were subjected to drop test. Accelerometer was mounted on the bottom of the slab to record the acceleration time graph. In the current study dynamic behaviour of HSC slabs were compared with the same configuration with entrenched strengthened slabs. The change in dynamic response was recorded and studied with the strengthening and found that dynamic parameters such as peak acceleration and damage index, measured as energy required to develop unit crack length caused by the impact were found to be dependent on the steel ratio. The strengthening technique was effective in reducing the peak acceleration of slabs.
