“…To date extensive experimental research has been conducted on RC pile caps to investigate the suitability of the different design methods (Magade and Ingle 2020). In addition, laboratory tests have been carried out to understand the flexure and shear behavior of RC pile caps (Park et al 2008).…”

Reinforced concrete (RC) Pile cap, a thick reinforced concrete block, is constructed to provide a connection between a structure and multiple single piles. In the existing design methods, the behavior of RC pile cap is usually considered as a rigid body and resulting forces or reactions on piles are assumed equal. However, in actual conditions, there is a possibility of bending of pile cap and unequal reactions or forces on piles. This study represents a detailed finite element analysis of RC eight-pile cap by using a computer program ATENA. ATENA serve as rational tools to explain the behavior of RC structures. Research parameters included different types of loading conditions, analysis types such as linear and non-linear, support conditions, length of pile, strength of concrete and thickness of pile cap. The finite element analysis results indicate that the behavior of RC pile cap is not a rigid body and resulting forces or reactions are unequal. Also, it was observed that, support conditions, analysis type and thickness of RC pile cap had a significant effect on the global behavior of RC pile caps.

“…Several codes, such as the American Concrete Institute (ACI-318) (2005), British Standards Institution (1990), British Standards Institution (1997), and Canadian Standards Association (1994), also assume the pile cap to be a beam element that requires longitudinal reinforcement [4]- [5]. Another method employed to obtain internal moments and shear forces is by mathematically modeling the pile cap as a thick shell element using the Finite Element Method (FEM) [6]. Furthermore, SNI 2847:2019 in Article 13.2.6.4 also states that the strut and tie method (STM) modeling should be allowed in the design of pile caps [3].…”

The Strut and Tie Method (STM) is one effective method for predicting the ultimate strength, failure modes, and behavior of reinforced concrete pile caps. However, the use of the strut and tie method in pile cap design in Indonesia is not as popular as the use of conventional methods. This study aims to evaluate the reinforcement design of pile caps using conventional methods and the finite element method (FEM) approach, utilizing the strut and tie method specified in SNI 2847 2019. The analysis results show that the required area of longitudinal reinforcement in the conventional method does not meet the criteria when evaluated using the STM method. The deficiency in the longitudinal reinforcement area amounts to 40.13% compared to the design results obtained using the STM method. Meanwhile, the use of the FEM method results in a required reinforcement area that exceeds the required area for the STM method. The difference in reinforcement is even greater, reaching up to 7.85% for the FEM method.
