Abstract

Tujuan penelitian ini untuk menganalisis perbandingan perilaku plastis dengan model bilinier dan strain hardening penampang twin box dan cellular box. Hal-hal yang dipelajari adalah hubungan momen-kelengkungan, momen plastis, panjang daerah inelastis dan faktor bentuk (shape factor). Jembatan yang dianalisis mempunyai panjang bentang 40 meter dan lebar 10 meter. Perencanaan penampang jembatan dilakukan dengan menggunakan bantuan program SAP 2000 versi 15, dengan mengikuti prosedur yang ditetapkan dalam RSNI T-03-2005. Beban yang diperhitungkan adalah beban mati dan beban hidup saja dan didasarkan pada RSNI T-02-2005. Kedua penampang direncanakan mempunyai momen leleh yang sama (dengan mendesain modulus penampang elastis yang sama). Untuk analisis dengan model bilinier dan model strain hardening momen plastis pada penampang twin box lebih besar dibandingkan cellular box. Kenaikan momen plastis terbesar akibat diperhitungkan strain hardening terdapat pada penampang twin box, yaitu sebesar 30,76%, sedangkan kenaikan terkecil terdapat pada penampang cellular box, yaitu sebesar 26,42%. Kenaikan daerah inelastis terbesar akibat diperhitungkan strain hardening terdapat pada penampang twin box. Akhirnya, dalam tulisan ini diperbandingkan hubungan momen-kelengkungan kedua bentuk penampang baik menggunakan model bilinier maupun menggunakan model dengan strain hardening

Abstract

This study compares plastic deformation behavior in box girder bridges with multiple boxes and cellular box cross-sections. The cross-section's shape significantly influences the girder's post-yield behavior despite being designed to have the exact yield moment. Steel's stress-strain relationship undergoes linear behavior until the yield stress is reached, followed by strain hardening. This study aims to assess the impact of strain hardening on the plastic behavior of girder box bridges.Two types of box girder sections, multiple box and cellular box, are designed with equivalent yield moments. The analysis is conducted with and without strain hardening calculations to evaluate plastic moment, inelastic area length, shape factor, and moment-curvature relationship. The design and analysis follow RSNI T-03-2005 standards using SAP 2000 v.15.Results indicate that multiple box sections exhibit more prominent plastic moments and inelastic area lengths than cellular box sections. Strain hardening calculations show significant increases in plastic moments for both section types. Graphical comparisons highlight the differences in moment-curvature relationships between models with and without strain hardening. Understanding the impact of strain hardening on plastic behavior provides valuable insights for designing and assessing box girder bridges, ensuring structural safety and performance under load conditions.
