Abstract: Penelitian ini bertujuan untuk menganalisis perilaku struktural elemen non-Bregion seperti pilecap secara lebih rasional melalui pendekatan Strut-and-Tie Model (STM). Metode konvensional seperti teori lentur Bernoulli seringkali dianggap tidak akurat untuk pilecap karena adanya diskontinuitas aliran gaya atau daerah Dregion. Penelitian ini menggunakan bantuan perangkat lunak Computer Aided Strut and Tie (CAST) untuk memvalidasi secara visual dan numerik distribusi gaya internal yang terjadi. Parameter perencanaan yang digunakan meliputi mutu beton (f'c) 25 MPa dan mutu baja (fy) 420 MPa dengan geometri pilecap persegi panjang. Hasil analisis menunjukkan bahwa metode STM mampu memodelkan aliran gaya tekan sebagai elemen strut dan gaya tarik sebagai elemen tie secara lebih realistis. Verifikasi menggunakan perangkat lunak CAST mempermudah evaluasi kapasitas pilecap dalam menyalurkan beban aksial dari kolom ke tiang pancang dengan akurasi yang lebih tinggi dibandingkan perhitungan manual. Penelitian ini diharapkan dapat menjadi referensi bagi praktisi dalam merencanakan struktur pondasi yang aman dan efisien sesuai standar SNI 2847-2019. This study aims to analyze the structural behavior of non-B-region elements such as pilecaps more rationally using the Strut-and-Tie Model (STM) approach. Conventional methods like Bernoulli's beam theory are often considered inaccurate for pilecaps due to discontinuities in force flow, known as D-regions. This research utilizes Computer Aided Strut and Tie (CAST) software to visually and numerically validate the internal force distribution. The design parameters include a concrete strength (f'c) of 25 MPa and steel strength (fy) of 420 MPa with a rectangular pilecap geometry. The analysis results show that the STM method provides a more realistic model by representing compressive force flows as strut elements and tensile forces as tie elements. Verification using CAST software facilitates the evaluation of pilecap capacity in transferring axial loads from columns to piles with higher accuracy compared to manual calculations. This study is expected to serve as a reference for practitioners in designing safe and efficient foundation structures in accordance with the SNI 2847-2019 standard.
