“…Fiber-reinforced concrete piles (FRCPs) have already attracted the attention of researchers. Accordingly, several experimental programs have been conducted to consider steel fiber-reinforced concrete (SFRC) as a structural material (Akdag and Özden 2013;Buyle-Bodin and Madhkhan 2002;Ozden and Akdag 2009;Sterin et al 1984). The purpose of these studies was to prove the postcracking, ductility, and fatigue performances of FRCPs; these properties are required (and mandatory) in deep foundations in soil with low cohesion, in seismically active zones (Ozden and Akdag 2009).…”

Currently, foundation piles for inhabited areas are often constructed using a continuous flight auger, which is a cost-and timeefficient technology that does not require stabilization of the borehole wall; the steel bar reinforcement is embedded after the concrete has been poured. However, this reinforcement operation can lead to severe construction and structural issues. Thus, several improvements to this technology have been proposed since its first application in the 20th century, such as the use of more fluid concretes. Nevertheless, steel and polymers are emerging as a potential replacement for steel bars in concrete reinforcement for several types of structures and building components, with identified and quantified benefits from a sustainability perspective. Accordingly, this paper proposes and validates a multicriteria decision-making approach designed with multidisciplinary experts within the construction field to assess the sustainability index of concrete pile foundations. The results of a case study enable us to conclude that polymeric fiber-reinforced concrete piles are the most sustainable due to their cost-structural efficiency ratio, high durability, and minimal risks during construction. Steel fiber-reinforced concrete alternatives were also found to be more sustainable than traditional reinforced concrete. Nonetheless, these results are unrepresentative of the current practice as direct costs were found to be the main driver in the decision-making processes, while other costs and both environmental and social indicators are disregarded. This justifies the urgency to provide sustainability-driven decision-making approaches capable of objectively quantifying the satisfaction degree of economic, environmental, and social indicators involved in the analysis.

In order to solve the problem of insufficient bearing capacity of existing concrete piles, a type of concrete pile with an additional lengthened strengthening core is designed, by inserting the steel tube through guiding hole and pouring core concrete. To reveal the mechanical performance of the reinforced piles, scale model tests and finite element simulations were performed. The results showed that both the vertical and horizontal bearing capacity increase with the length of the stiffening core. The axial force of the enhanced core is also smaller than conventional concrete piles, and the extended core can share the axial force of the foundation pile to improve the stress distribution of the pile body. These findings point toward a useful and general method for increasing the load capacity of existing concrete piles.

“…Bransby and Springman (1999) presented a finite element study to determine the pile-soil-pile interaction behaviour for closely spaced pile rows and groups under passive lateral loading from soil movement. Ozden and Akdag (2009) discussed the modelling considerations, results and analyses of monotonic lateral load tests on SFRC model piles surrounded by a cohesionless soil layer in a testing pool. Etedali and Irandegani (2011) evaluated the nonlinear static analysis of structures under two lateral load patterns, including uniform and triangular lateral load patterns.…”

This paper develops a new method to directly determine the composite elastic modulus of the reinforced concrete cantilever pile rather than adopt theoretical or empirical approaches. On the basis of the theory of material mechanism, the load-deflection equation was deduced to create the relationship between the elastic modulus and the ratio of load-deflection. The numerical modelling tests based on ANSYS separation modelling technology were carried out to determine the composite elastic modulus under different reinforcement ratio, concrete strength grade and distribution pattern of driving force. The results can be used to create the quantitative relationship between the composite elastic modulus and reinforcement ratio as well as concrete strength grade. Comparison amongst various lateral load pattern were made to show that the deflection of pile head is obviously affected by the lateral load pattern, and the corresponding equations of the deflection of the pile head under different lateral load pattern were proposed, which can reflect the ranking of the great influence on the deflection of the pile head, rectangular, trapezoidal and triangular lateral load pattern in order.
