The study investigated the applicability of a freestanding retaining wall system, with a combination of H-beams and precast concrete blocks. Additionally, the study utilized finite element analysis in ABAQUS. The concrete damaged plasticity and Mohr–Coulomb models were employed to model concrete and soil, respectively. The key parameters included H-beam size (100 × 100, 200 × 200, and 300 × 300 mm), wall height (6.0, 4.5, and 3.0 m), and embedment depth (3.0, 2.5, 2.0, and 1.5 m), with displacement limits of 24, 18, and 12 mm. For 6.0-m walls, only the 300 × 300-mm H-beam with a 3.0-m embedment met the displacement criteria. Most combinations for the 4.5- and 3.0-m walls met the criteria, with the exception of the smallest displacement limit at 4.5-m walls with reduced embedment. The results showed that, assuming proper embedment, wall behavior is governed by H-beam stiffness, with 300 × 300-, 200 × 200-, and 100 × 100-mm beams suitable for 6.0-, 4.5-, and 3.0-m walls, respectively.
