Structural behavior of reinforced concrete one-way slabs voided by polystyrene balls

摘要

In the last two decades, the use of voided (bubbled) slabs in constructions has been Received 1 July 2019 increased because of several advantages such as light self-weight, cost-saving, and Received in revised form 13 October 2019 accelerated construction schedules. However, the structural behavior of such slabs has not Accepted 14 October 2019 been adequately inspected, especially for one-way slabs. Therefore, this paper presented an experimental investigation to assess the effect of voids’ size on the structural behavior of one-way slabs. Four slabs were fabricated using self-compacting concrete. Three of them were bubbled slabs, containing 68 polystyrene balls with different sizes (60 mm, 70 mm, and 90 mm); these balls were regularly distributed inside the slabs. The fourth slab was.
