ANALISIS PENJALARAN SUHU TINGGI PADA PENAMPANG BALOK BETON BERTULANG

Abstract

Peristiwa kebakaran merupakan peristiwa yang dapat mempengaruhi kestabilan elemen struktur, salah satunyaadalah elemen balok beton bertulang. Suhu tinggi akibat kebakaran dari luar balok mempengaruhi kekuatanelemen struktur. Suatu elemen harus dapat mempertahankan kekuatannya selama terpapar suhu tinggi. Olehkarena itu, analisis mengenai distribusi temperatur akibat suhu tinggi pada penampang elemen balok betonbertulang merupakan suatu hal yang penting untuk diidentifikasi. Distribusi temperatur berkaitan dengantransfer panas pada elemen balok beton bertulang akibat perbedaan temperatur pada penampang balok, yangdipengaruhi oleh sifat thermal material balok. Tujuan dari penelitian ini adalah untuk mengidentifikasi distribusitemperatur pada penampang balok bertulang akibat suhu tinggi pada durasi tertentu. Model yang digunakanadalah elemen balok beton bertulang dengan mutu beton 35 MPa dan mutu tulangan 400 MPa. Analisisdistribusi temperatur menggunakan metode Wickström dan analisis program elemen hingga LUSAS v.16.Berdasarkan hasil analisis kedua metode tersebut, dapat disimpulkan bahwa semakin lama durasi pemanasanpada balok, maka bagian dalam penampang balok akan semakin mengalami kenaikan temperatur. Sedangkanperbandingan antara kedua metode tersebut didapatkan bahwa nilai suhu pada titik tengah penampang padametode LUSAS lebih besar 245,237°C daripada hasil perhitungan metode Wickström, sedangkan penjalaranpanas pada metode Wickström kurang lebih 3 jam lebih lambat daripada penjalaran panas analisis LUSAS.
