Kuat Geser Dan Daktilitas Pada Balok Castellated Modifikasi Komposit Mortar Akibat Beban Siklik
Keywords:
balok, castellated-composit, siklik, kapasitas geser ultimite, beban maksimalAbstract
Struktur baja castellated merupakan struktur yang terbuat dari balok IWF yang memiliki bukaan lubang berupa heksagonal, lingkaran, maupun persegi. Dengan adanya bukaan lubang maka akan menambah ketnggian penampang yang mampu meningkatkan momen inersia yang terjadi pada balok, sehingga beban maksimum yang dapat dipikul balok juga akan meningkat, namun balok tersebut juga memiliki kelemahan yaitu terjadinya mekanime vierendeel. Oleh karena itu, Pada penelitian ini dikaji perilaku balok castellated komposit mortar akibat beban siklik yang memodelkan beban gempa di lapangan. Tujuan dari penelitian ini adalah untuk mendapatkan kekuatan ultimte, daktilitas, dan pola keruntuhan pada balok castellated komposit mortar. Benda uji terbuat dari profil 2L.30.3.3, tulangan ø 13 mm, dan mortar yang memiliki nilai fas 0,4 dengan perbandingan
1:1,5. Beban siklik yang diaplikasikan mengacu pada ACI T1.1-01. Berdasarkan hasil penelitian didapatkan nilai kapasitas beban ultimate pada balok sebesar 203,5 kN untuk siklus positif dan 201,5 untuk siklus negatif. Lendutan yang terjadi sebesar 3,46 mm untuk siklus positif dan 3,36 untuk siklus negatif. Nilai daktilitas rata-rata yang didapat sebesar 3,45. Dari hasil tersebut dapat diklasifikasikan bahwa struktur memiliki tingkat daktilitas sedang.
