摘要：
The behaviour of engineered cementitious composites (ECC) specimens using polyvinyl alcohol (PVA) fibres and hybrid engineered cementitious composites (HECC) using PVA fibres and steel fibres (two different types) was experimentally investigated. The experiments included compression and flexural tests at different temperatures ranging from 20 degrees C to 600 degrees C. Under uniaxial compression load the HECCs specimens produced less debris (from 200 degrees C to 600 degrees C) compared to ECC counterparts. The flexural tests results revealed that the load bearing capacity and deflection of HECCs specimens were less vulnerable up to 100 degrees C compared to ECC specimens. Under higher temperatures the ECC specimens' behaviour was brittle, while HECCs specimens exhibited a deflection-softening behaviour. Then a finite element model was employed to investigate the flexural tests results obtained from experiments. (C) 2017 Elsevier Ltd. All rights reserved.
