Analytical and Numerical Investigation of the Behavior of Engineered Cementitious Composite Members under Shear Loads

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

“…Finite element analysis has gradually developed into an extremely crucial research tool that has been used to supplement and expand experiments by many scholars in engineering, biology, medicine, and aeronautic fields specimen in the group. Additional details on the experimental program are available in the literature [44,45]. It can solve several difficulties of experiments, such as long experimental periods, discrete results, and limited research parameters.…”

Bond behavior is a key factor in the engineering application of composite material. This study focuses on the constitutive model of the bond behavior between high-strength stainless steel strand mesh and Engineered Cementitious Composites (ECC). In this paper, the effects of strand diameter, bond length and transverse steel strand spacing on bond behavior were studied based on 51 direct pullout tests. Experimental results showed that the high-strength stainless steel strand mesh provided specimens an excellent ductility. Based on the experimental data, the existing bond–slip model was revised using the theory of damage mechanics, which fully considered the influence of the steel strand diameter on the initial tangent stiffness of the bond–slip curve. The results of the model verification analysis show that errors are within 10% for most parameters of the bond–slip model proposed, especially in the ascending section, the errors are within 5%, indicating that the calculated results using the revised model are in good agreement with the test results. In addition, the revised model was applied to the finite element analysis by using the software ABAQUS to simulate the pullout test, in which the spring-2 nonlinear spring element was used to stimulate the bond behavior between steel strand meshes and ECC. The simulation results show that the numerical analysis fits the experimental result well, which further verifies the accuracy of the model and the feasibility and applicability of the numerical analysis method.

“…Oil-coated polyvinyl alcohol (PVA) fibers have been most commonly used in the manufacture of ECC; however, recent studies show that highly ductile ECCs could also be developed using the non-oil-coated, low tensile strength PVA fiber by re-tailoring the matrix [27]. In a more recent study by Arulanandam et al [28], an approach using a thorough analytical and finite element analysis (FE) has been used to study the performance of engineered cementitious composite (ECC) beams with and without transverse reinforcements. In a follow-up study by Maheswaran et al [29], the shear behavior of engineered cementitious composite beams with a hybrid mix of polyvinyl alcohol (PVA) and polypropylene (PP) fibers was investigated experimentally and numerically.…”

“…In this context, zeolite and silica fume were selected and added to ECCs since they can improve the microstructure of the evaluated concrete; thereby enhancing its performance and permeability properties. In addition, to determine the difference between the performance of the (polyvinyl alcohol) PVA-ECC specimens subjected to the sulfate medium and lab conditions and those of the (polypropylene) PP-ECC specimens, compressive strength, flexural strength, and midspan deflection were measured at four (28,150,180, and 210 days) concrete ages.…”

Over the past two decades the effects of different admixtures have been investigated on mechanical properties and durability of engineered cementitious composites (ECC). Despite this, materials such as silica fume and zeolite have not been thoroughly investigated. The present study was designed and implemented to evaluate the effects of silica fume, zeolite, and blast furnace slag (BFS) on engineered cementitious composites and to compare the mechanical properties and durability of the polyvinyl alcohol-ECC (PVA-ECC) and polypropylene-ECC (PP-ECC) specimens. For this purpose, specimens were subjected to adverse conditions in a 5% magnesium sulfate solution and lab conditions as the reference treatment to measure the post-treatment variations in their compressive strength, flexural strength, and mid-span deflection (MSD). Results demonstrated that PP-ECC was not only easier to manufacture but outperformed PVA-ECC in some respects as well. It was also observed that MSD increased in the PVA-ECC specimens but declined in the PP-ECC ones under identical increments in their BFS contents. Finally, all the specimens maintained under the lab conditions displayed the best performance in terms of strength and durability when 3% silica fume was added to their mixtures while the same addition led to the worst performance in the sulfate medium.
