Perancangan Jembatan I Girder Prategang
Webinar Jakon Jabar Series 3
Materi ini membahas secara komprehensif konsep dan tahapan teknis dalam perencanaan jembatan menggunakan I-Girder Beton Prategang (PCI) untuk skala bentang 10 hingga 50 meter. Pembahasan diawali dengan pemahaman dasar mengenai konfigurasi jembatan, komponen utama I-Girder, kriteria pembebanan, serta prinsip kerja gaya prategang.
Selanjutnya, materi ini memperdalam aspek mekanika struktur melalui analisis metode konstruksi pratarik maupun pascatarik, pemodelan sistem tendon, dan perhitungan kehilangan gaya prategang (prestress losses). Evaluasi kinerja struktur juga dilakukan melalui pengecekan batas tegangan izin beton pada kondisi transfer dan layan dengan bantuan Diagram Magnel.
Pada bagian akhir, dibahas analisis kekuatan struktur terhadap beban lentur dan geser untuk memastikan keamanan komponen jembatan. Keseluruhan konsep teknis ini kemudian diterapkan langsung dalam studi kasus perhitungan praktis desain PCI Girder bentang 40 meter.
