Blast responses of one-way sea-sand seawater concrete slabs reinforced with BFRP bars

摘要

Avoiding steel corrosion in seawater sea-sand concrete (SSC) members, basalt fiber reinforced plastic (BFRP) bars behaving as reinforcement have advantages in coastal civil engineering and protective structures. One-way BFRP-bar reinforced SSC slabs (BRSSs) were designed to investigate their mechanical responses under static loads and close-in explosions. The SSC blocks have comparable quasi-static compressive strength with plain concrete blocks. The BRSSs have comparable quasi-static flexural strength and identical failure mode with the BFRP bars reinforced plain-concrete slabs (BRPSs). Under close-in explosions, the BRSSs have comparable blast resistance and similar failure modes with the BRPSs. Together with the excellent anti-corrosion ability, the BRSS is an ideal selection for costal protective structures. (C) 2019 Elsevier Ltd. All rights reserved.
