“…Meanwhile, the substructure has foundation elements and pile caps [1]. The pile cap element transfers the load from the superstructure to the ground or substructure [2]. Fundamentally, pile caps are a plate element with a greater thickness than floor slabs.…”

“…The pile cap is assumed to be an inverted beam element that supports bending moments and shear forces. 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].…”

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.

“…Strut and tie modeling (STM) is considered one of the most influential approaches to analyze RC deep beams where D regions occur [6][7][8][9][10][11][12][13][14][15]. The STM approach assumes a truss that contains compression members (struts) that are linked to tensile members (ties) in specific points (nodes) [16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”

The current research work summarizes some previous research works on horizontally curved beams. Because of curvature, torsional effects in the analysis and design should be included. Diameter of ring beam, number of supports, beam width, compressive strength of the concrete, and bearing plate width. Which can be summarized from previous studies is that increasing diameter of ring by about 25-75% decreases the capacity load by about 14-36%, while increasing number of supports by about 33-100%, beam width by about 25-75%, compressive strength of concrete by about 24-76%, and bearing plate width by about 25-75% increases the capacity load by about 62-189%, 25-75%, 24-76%, and 5-16%, respectively due to the beam section increase and/or its properties. Frequently, reinforced concrete deep ring beams exhibit shear failure in a manner similar to straight beams. Strut and tie model (STM) and plastic analysis are useful tools for efficiently analyzing ring or curved deep beams. In addition, the nonlinear three-dimensional finite element modeling is typical for predicting the deep curved beams strength and behavior.

“…; and (b) The depth of member (h) is not more than four times the clear span''. However, the majority of existing research into the behavior of structure and deep members' strength has been limited to deep beams of single span [3][4][5][6][7] and continuous deep beams [8][9][10][11][12][13], pile caps [14][15], corbels [16][17][18][19][20][21][22][23] but not take care on ring deep beams.…”

A Finite Element Parametric Study of Reinforced Concrete Horizontally Circular Deep Beams

et al. 2021

A parametric study of twenty-five reinforced concrete ring deep beams using finite element analysis is presented in this study. This paper took into account the kind of loading (partial and complete), the diameter, depth, and width of the ring beam, as well as the NO. of supports. When compared to equivalent concentrated central loading, acting a central partial distributed loading of 25-100 percent of the length of span increased capacity of load by about 3-80 percent while decreasing max. deflection and moments of torsion by about 4-14 percent and 1-9 percent, respectively. Decreases in load capacity of about 10-33 percent were observed when beam diameter was increased by 20-80%, while deflection and moments of torsion increased by about 30-145 percent and 8-23 percent, respectively. When the depth of the beam was increased by 12-50 percent, the capacity of load and moments of torsion increased by about 15-61 percent, while deflection reduced by about 8-21 percent. When the circular beam width was increased by 40-160 percent, the capacity of load, deflection, and moments of torsion increased by about 142-690 percent, 26-62 percent, and 137-662 percent, respectively. Finally, when the NO. of supports increased by 25-150 percent, the capacity of load increased by about 70-380 percent, while the deflection and moments of torsion decreased by about 27-71 percent and 16-72 percent, respectively.
