Abstract
This paper presents on the low velocity impact loading on plain slab concrete. There are three different thicknesses of concrete slabs; namely 20 mm, 30 mm, and 40 mm, all of which have been subjected to 1 blow of impact from 1.25 kg steel ball per slab. The resulting deflections and stresses on the concrete midspan was then observed. It was found that the highest deflection occurs for the concrete slab with the 20 mm thickness with a value of 9.965 mm, while the lowest deflection was found to be at 4.157 mm for the slab thickness of 40 mm. The highest mid-span stress occured at 20 mm slab for 500 mm drop height. During impact it was observed the slab is still in elastic linear region. � The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
