Effect of ECC layer thickness and reinforcement ratio on the load carrying capacity of steel‐reinforced composite beams

Abstract

The present study investigates the effect of Engineered Cementitious Composites (ECC) layer thickness against various reinforcement ratios on the flexural performance of reinforced ECC-concrete composite beams. In total, 20 reinforced composite beams are selected from the literature to predict their flexural response using Finite Element (FE) analysis. In addition to the FE analyses, a detailed analytical study is performed using the strain compatibility procedure to predict the flexural strength of ECC-concrete composite beams. The results from the FE analyses are compared against the experimental results and are found to show a close agreement. Using the validated FE models, detailed parametric studies are conducted to determine the effectiveness of different design parameters such as (a) ECC height replacement for a reinforcement ratio, (b) reinforcement ratio for an ECC height replacement, and (c) adequate

A Review of Delamination Damage of Composite Materials

“…Furthermore, the partial fracture toughness in composites of unidirectional layers significantly depends on the difference in the directions of stacking of adjacent layers [107,108] and on the thickness of the layer [109,110], i.e., they are constants of the composite.…”
