Abstract
Jembatan Lemah Ireng II terletak pada STA 21+912 ~ STA 22+410 jalan tol Semarang-Bawen. Jenis jembatan Multi Span Continuous I-Girder dengan panjang bentang 298,15 dan lebar 2x12 m. Pada struktur bawah jembatan terdapat enam pilar dan dua abutmen. Perencanaan ulang dilakukan dengan menggunakan jembatan busur rangka baja menerus dengan lebar 12 m dan tinggi busur 20 m. Desain jembatan busur menerus terbagi menjadi dua bagian yaitu, bentang tengah 100 m dan dua bentang tepi 50 m.
Perencanaan bangunan atas jembatan Lemah Ireng II menghitung antara lain, struktur lantai kendaraan, struktur baja ikatan angin, struktur baja rangka utama, struktur sambungan, dan desain perletakan. Dalam perencanaan ini harus memenuhi peraturan terbaru, antara lain SNI 1725:2016, RRSNI T-03-2005, SNI 2833:2008, SNI 2847:2013 serta peraturan lain yang berkaitan dengan perencanaan jembatan baja. Perencanaan rangka utama menggunakan kombinasi KUAT 1 (SNI 1725:2016), sedangkan perencanaan ikatan angin menggunakan kombinasi KUAT 3 (SNI 1725:2016). Perencanaan bangunan bawahpada tugas akhir ini menghitung struktur abutment, struktur pilar, dan pondasi bored pile. Abutment dan pilar menggunakan struktur beton bertulang sesuai dengan SNI 2847:2013.
Hasil dari analisa struktur diperoleh: tebal pelat lantai kendaraan 20 cm, dimensi ikatan angin terbesar CHS 267,4x7, dimensi struktur rangka utama terbesar BOX 600x600x25, dimensi struktur rangka diagonal terbesar BOX 400x400x25, dimensi portal akhir BOX 600x600x25, diameter kabel penggantung 45 mm, perletakan menggunaan tipe POT bearing. Pondasi yang digunakan berupa pondasi bored pile dengan jumlah tiang pada abutment sebanyak 21 buah dan jumlah tiang pada pilar sebanyak 60 buah.
============================================================
Lemah Ireng II bridge located at Semarang-Bawen Toll Road STA 21+912 ~ STA 22+410. Type of bridge is Multi Span Continuous I-Girder with length 298,15 m and width 2x12 m. In the substructure there are six piers and two abutments. Redesign is done by using continuous steel arch bridge with width 12 m and height of arch 20 m. Continuous arch bridge design is divided by middle span with length 100 m and side span with length 50 m on left and right side.
The design on Lemah Ireng II bridge calculates secondary structure, steel wind bracing structure, main steel structure, connection structure and bearing structure. The design have to fulfill the latest regulations, such as SNI 1725:2016, RRSNI T-03-2005, SNI 2833:2008, SNI 2847:2013, also other regulations corresponding to steel bridge design. The design of main frame using combination of KUAT 1 (SNI 1725:2016), and the design of wind bracing using combination of KUAT 3 (SNI 1725:2016). Substructure design in this final project calculates abutment structure, pier structure, and bored pile foundation. Abutment and piers are made by reinforced concrete structure in according to SNI 2847:2013.
Base on the structure analysis, the output from this final project are obtained: 20 cm thick plate of floor, CHS 267,4x7 as the biggest dimension of wind bracing, BOX 600x600x25 as the biggest dimension of main frame structure, BOX 400x400x25 as the biggest dimension of diagonal frame structure, BOX 600x600x25 as the dimension of end portal, cable hanger with diameter 45 mm, POT bearing type is used to bearing structure. The substructure using bored pile foundation with 21 pieces of pile on abutment and 60 pieces of pile on pier.
