Abstract
Tujuan penelitian ini adalah untuk mengevaluasi sisa kapasitas kekuatan korosi pelat baja yang terlihat pada bagian struktur baja yang mengalami beban tekuk agar tetap pada kondisi layak digunakan, hingga perlu pebaikan atau rekonstruksi pada waktu yang tepat. Pelat baja ini diperoleh dari potongan girder jembatan yang mengalami korosi karena adanya reaksi kimia dengan lingkungan sekitarnya selama bertahun-tahun dan mereduksi ketebalannya serta membentuk permukaannya menjadi irreguler. Kemudian, spesimen uji tersebut dibentuk sesuai standar specimen pengujian Japanese Industrial Standard JIS No. 5 dan dianalisis secara eksperimen untuk mengevaluasi sisa kapasitas kekuatannya. Parameter yang diperhitungkan pada pengujian ini yaitu nilai ketebalan minimum, permukaan irregular korosi baja dan eksentrisitasnya. Dari hasil pengujian korosi pelat baja yang mengalami beban tekuk kompresi ini dapat disimpulkan bahwa konfigurasi permukaan dan eksentrisitasnya menurunkan kemampuan korosipelat baja dalam memikul beban.References
