Abstrak

ABSTRAK Banyak diketahui bahwa pelat (slab decks) merupakan komponen struktur jembatan yang mengalami efek pembebanan secara langsung sehingga mudah mengalami kerusakan, salah satu adalah Jembatan Noenebu yang menjadi objek pada penelitian ini. Jembatan ini terletak pada daerah Kecamatan Kefamenanu Kabupaten Timur Tengah Utara (TTU) Provinsi Nusa Tenggara Timur, telah mengalami penurunan kekuatan dengan tanda-tanda kerusakan yaitu retak-retak pada pelat beton sehingga digunakan material perkuatan beton berupa GFRP. Tujuan penelitian ini untuk membandingkan kinerja pelat lantai jembatan saat sebelum dan sesudah diperkuat dengan GFRP. Analisis data pada penelitian ini menitikberatkan pada perbandingan hasil defleksi antara pengujian langsung lapangan menggunakan static loading test dengan analisis SAP 2000 dan perhitungan manual terhadap pembebanan lapangan dan standar (RSNI T-02-2005) dengan batasan lendutan maksimum jembatan. Berdasarkan hasil perhitungan pembebanan lapangan diperoleh: persentase pengurangan hasil defleksi tanpa perkuatan GFRP dibandingkan dengan setelah diberikan perkuatan GFRP pada pengujian langsung lapangan, analisis SAP 2000, dan perhitungan manual secara berurutan yaitu 4,934 %, 0,7097 %, dan -0,6804 %. Berdasarkan hasil defleksi dari perhitungan pembebanan standar: persentase pengurangan hasil defleksi tanpa perkuatan GFRP dibandingkan dengan setelah diberikan perkuatan GFRP pada analisis SAP 2000 dan perhitungan manual secara berurutan yaitu 2,0212 % dan -0,17557 %. Nilai defleksi yang dihitung masih dibawah batas lendutan jembatan L/240 yaitu 18,75 cm. Kata kunci : Defleksi, Perkuatan GFRP, Jembatan Noenebu. ABSTRACT It is well known that plate (slab decks) is a component of the bridge structure having direct loading effect easily damaged, which one of them was Bridge Noenebu as object in this study. This bridge is located in the sub-district of Kefamenanu, Timur Tengah Utara (TTU) regency Nusa Tenggara Timur Province, has been decreasing strength with signs of damage i.e. cracks in the concrete slab that used concrete reinforcement material in the form of GFRP. The purpose of this study to compare the performance of the floor plate before and after the bridge reinforced with GFRP. Analysis of the data in this study is focused on a comparison of the results of direct testing deflection field with SAP 2000 analysis and manual calculation of loading field and standard (RSNI T-02-2005) with a maximum deflection limit bridge. Based on the results obtained by calculation of loading field: percentage reduction of deflection test results without the GFRP reinforcement compared to after given the GFRP reinforcement on direct testing field, SAP 2000 analysis, and manual calculation respectively, they are obtained 4.934 %, 0.7097%, and -0,6804 %. Based on the results of the calculation deflection of the loading standard: percentage reduction of deflection test results without the GFRP reinforcement compared to after given the GFRP reinforcement on SAP 2000 analysis and manual calculation respectively, they are obtained 2,0212 % and -0.17557 %. The Values of deflection are calculated still below 18.75 cm as deflection limit L/240. Key words: Deflection, GFRP Reinforcement, Noenebu Brigde .
