Abstract

Penggunaan balok baja dengan menggunakan castellated beam selain dapat mengurangi biaya konstruksi dan membuat bahan menjadi lebih ringan jika dibanding dengan profil dengan dimensi yang sama, juga akan membuat momen inersia dan section modulus yang lebih besar, sehingga mampu memikul momen yang lebih besar dan tegangan ijin yang lebih kecil. Tugas Akhir ini difokuskan untuk menganalisa perbandingan model keruntuhan bukaan castellated beam, dengan dua jenis bentuk bukaan yaitu circular dan hexagonal antara solid beam IWF 250.125.6.9, IWF 400.200.8.13 dan IWF 450.200.9.14 yang sebelumnya telah direncanakan menjadi castellated beam. Hasil pemodelan dan analisa keruntuhan balok castellated beam menyimpulkan bahwa balok dengan bukaan hexagonal memiliki kekakuan yang lebih baik dari pada balok dengan bukaan circular pada sampel yang sama, hal ini ditunjukan dengan perbedaan nilai persentase tegangan sebesar 5,126% dan defleksi 7,852% pada balok circular castellated beam ============================================================================================= The use of steel beams using a castellated beam in addition to reducing the construction cost and make the material becomes lighter when compared to the profiles with the same dimensions, also will make the moment of inertia and section modulus greater, so as to bear a greater moment and the allowable stress smaller. This final project is focused on analyzing of the failure model comparison openings castellated beam, with two types of forms are circular and hexagonal openings between the solid beam IWF 250.125.6, IWF 400.200.8.13 and IWF 450.200.9.14 which previously had been planned to be a castellated beams. The results of the modeling and failure analysis of castellated beams beam concluded that beams with hexagonal openings have better stiffness of the beam with circular openings on the same sampel, it is indicated by the difference of percentage value of the tension is 5.126% and deflection value is 7.852% on the circular castellated beams
