Abstract


Detailing tulangan pengekang kolom balok persegi pada struktur kolom beton bertulang yang dibangun di daerah rawan gempa memerlukan perhatian khusus mengingat banyaknya kegagalan struktur yang terjadi di lapangan akibat kurangnya pemahaman yang benar mengenai konsep desainnya maupun kesalahan implementasinya di lapangan. Building Code Requirements for Reinforced Concrete and Comentary (ACI 318-14) yang diikuti oleh SNI 2847-2019 melakukan perubahan signifikan pada perhitungan luas tulangan pengekang yang memasukkan unsur tulangan longitudinal khususnya pada kolom dengan beban aksial yang tinggi atau mutu beton diatas 70 MPa untuk sistem rangka pemikul momen khusus dalam rangka meningkatkan kemampuan daktilitasnya. Penelitian ini merupakan studi parametrik menggunakan data eksperimental yang tersedia. 22 kolom persegi beton bertulang dari mutu beton 29-88 MPa serta konfigurasi tulangan mulai dari konfigurasi tanpa pengikat silang (cross ties) hingga kolom dengan 3 kaki pengikat silang pada tiap sisinya. Data penelitian yang ada dievaluasi dan analisis untuk mendapatkan daktilitas lateral maupun kurvaturnya. Hasil dari studi ini menekankan perlunya penggunaan pengikat silang yang mengekang secara lateral tulangan longitudinal, penggunaan pengikat silang memberikan peningkatan daktilitas yang signifikan, standar luas tulangan pengekang terbaru memberikan tingkat daktilitas yang lebih baik dari sebelumnya.
