Kolom merupakan elemen struktur yang berfungsi memikul beban tekan vertikal dari balok, pelat, dan elemen struktur di atasnya. Kegagalan kolom dapat menyebabkan keruntuhan bangunan secara progresif sehingga perkuatan diperlukan apabila terjadi penurunan kapasitas. Penelitian ini bertujuan menganalisis pengaruh baja siku sebagai perkuatan eksternal terhadap perilaku kolom beton bertulang. Analisis dilakukan secara numerik menggunakan metode elemen hingga dengan bantuan perangkat lunak ATENA 3D. Model kolom berukuran 150×150 mm dengan tulangan utama 4D12 mm, tulangan sengkang Ø6-150 mm, dan tebal selimut beton 20 mm. Perkuatan dipasang pada keempat sudut kolom menggunakan baja siku berukuran 20×20×3 mm, 30×30×3 mm, dan 40×40×3 mm yang diikat dengan baja strap berukuran 19×0,8 mm pada jarak 150 mm. Model numerik divalidasi terhadap hasil eksperimen penelitian sebelumnya dan menunjukkan kesesuaian yang baik, dengan perbedaan kapasitas beban maksimum sebesar 3,93% pada kolom kontrol dan 4,77% pada kolom yang diperkuat. Hasil analisis menunjukkan bahwa perkuatan baja siku meningkatkan kapasitas tekan aksial, kapasitas deformasi, kekakuan, dan daktilitas kolom beton bertulang. Kapasitas tekan meningkat sebesar 31,69%, 39,03%, dan 48,34% pada model KBS20, KBS30, dan KBS40, sedangkan kekakuan dan daktilitas meningkat hingga masing-masing 24% dan 58% dibandingkan kolom kontrol. Dengan demikian, baja siku sebagai perkuatan eksternal terbukti efektif dalam meningkatkan kinerja struktural kolom beton bertulang terhadap beban aksial tekan. Meskipun demikian, karena penelitian ini merupakan studi numerik parametrik, efektivitas penerapan baja siku berukuran 20×20×3 mm dan 40×40×3 mm masih memerlukan verifikasi melalui pengujian eksperimental.
