Abstract
Penelitian ini membahas tentang studi perbandingan analisis kolom dengan variasi
bentuk penampang kolom yang berbeda antara kolom + (Plus–shaped column)
dan kolom beton bertulang berbentuk persegi. Penelitian ini bertujuan untuk
menganalisis seberapa besar pengaruh perubahan bentuk kolom terhadap kekuatan
struktur kolom. Perhitungan ini terdiri dari 120 sampel dengan perbedaan mutu
beton (fc’), rasio tulangan dan dimensi kolom pada masing-masing sampel.
Analisis perhitungan kolom menggunakan hubungan diagram tegangan regangan
Hognestad. Hasil penelitian, semakin besar rasio tulangan maka selisih nilai Mn
kolom + (Plua-shaped column) dan kolom persegi untuk tiap luasan, semakin
besar. Semakin besar rasio tulangan maka selisih nilai Pn kolom + (Plus-shaped
column) dan kolom persegi untuk tiap luasan semakin kecil.
Kata kunci : kolom beton bertulang, kolom + (Plus-shaped column), rasio
tulangan, kapasitas kolom.
