Abstract

Jembatan Trisula merupakan jembatan yang penghubung di atas Sungai Brantas, memiliki panjang bentang 200 m dan lebar lantai kendaraan 12 meter. Kondisi eksisting jembatan adalah jembatan rangka baja dengan pembagian 3 bentang yang didukung dengan menggunakan 2 (dua) pilar dan 2 (dua) abutment, karena hal demikian lebar sungai menjadi kurang lebar dikarenakan kebutuhan pilar, sehingga tidak cocok untuk tipe jembatan bentang panjang karena berpengaruh pada kekuatan pondasi yang dibutuhkan. Pada tugas akhir ini penulis menarik kasus yang tersedia, untuk memberikan referensi permodelan ulang Jembatan Trisula dengan struktur asymmetric cable stayed untuk mengurangi jumlah pilar untuk memperlebar aliran sungai, dan sebagai icon baru di Kota Blitar. Tugas akhir ini membahas “Desain Jembatan Asymmetric Cable Stayed Trisula Blitar” yang berada di daerah Kademangan Kota Blitar. Desain jembatan asymmetric cable stayed berkonsep pada struktur yang dapat memikul elemen horizontal kaku oleh deretan kabel lurus yang dibentangkan miring dan dihubungkan ke menara sebagai penahan utama, dengan metode balanced cantilever. Program bantu berupa software MIDAS CIVIL pada struktur atas dan SAP 2000 pada struktur bawah, dan mengacu pada berbagai peraturan sesuai standar SNI 1725 2016, SNI 2833 2016, RSNI 2833 2016, RSNI T 02 2005, AISC 360 - 10, ACI 318 - 08. Hasil dari desain ini didapatkan struktur lantai kendaraan dengan tebal 250 mm dengan penebalan aspal 50 mm, gelagar jembatan menggunakan baja WF 800.300.26.18 pada gelagar melintang, WF 600.300.12.20 pada gelagar memanjang, WF 200.200.8.12 pada gelagar kantilever, gelagar memanjang utama sebagai batang tekan adalah box girder dengan dimensi 1,5 m x 0,9 m, pylon dengan dimensi 5 m x 3 m, dimensi kabel dan angkur menggunakan VSL2000 unit 6, dan jenis pondasi yang digunakan berupa bored pile dengan diameter 1 m. Komponen – komponen penyusun struktur jembatan kemudian dikontrol terhadap stabilitas, dengan mengacu pada peraturan yang ada.

The Trisula Bridge is a connecting bridge over the Brantas River, has a span length of 200 m and a vehicle floor width of 12 meters. The existing condition of the bridge is a steel frame bridge with a division of 3 spans which is supported using 2 (two) pillars and 2 (two) abutments, because of this the river width becomes less wide due to the need for pillars, so it is not suitable for a long span bridge type because it affects the required foundation strength. In this final assignment the author draws on the available cases, to provide a reference for the remodeling of the Trisula Bridge with an asymmetric cable stayed structure to reduce the number of pillars to widen the river flow, and as a new icon in Blitar City. This final assignment discusses "Design of the Trisula Blitar Asymmetric Cable Stayed Bridge" which is in the Kademangan area of Blitar City. The asymmetric cable stayed bridge design has the concept of a structure that can support rigid horizontal elements by a row of straight cables stretched at an angle and connected to the tower as the main support, using the balanced cantilever method. The auxiliary program is MIDAS CIVIL software on the upper structure and SAP 2000 on the lower structure, and refers to various regulations according to the standards SNI 1725 2016, SNI 2833 2016, RSNI 2833 2016, RSNI T 02 2005, AISC 360 - 10, ACI 318 - 08. The results of this design obtained a vehicle floor structure with a thickness of 250 mm with an asphalt thickness of 50 mm, the bridge girder uses steel WF 800.300.26.18 on the transverse girder, WF 600.300.12.20 on the longitudinal girder, WF 200.200.8.12 on the cantilever girder, the main longitudinal girder as The compression member is a box girder with dimensions of 1.5 m x 0.9 m, a pylon with dimensions of 5 m x 3 m, cable and anchor dimensions using VSL2000 unit 6, and the type of foundation used is a bored pile with a diameter of 1 m. The components that make up the bridge structure are then controlled for stability, referring to existing regulations.
