Abstract

Jembatan Gumayang merupakan jembatan yang terletak di Jalan Tol Semarang-Demak STA 19+600. Jembatan Gumayang memiliki panjang 125 meter dengan lebar 35 meter yang terbagi menjadi 3 span, masing-masing span memiliki bentang yang berbeda-beda yaitu 31 meter, 47 meter, dan 47 meter. Struktur atas Jembatan Gumayang ditopang oleh 4 buah pilar. Jembatan Gumayang akan dikerjakan dengan struktur PCI girder sebanyak 14 buah. Permasalahan pada jembatan ini yaitu konstruksi tidak boleh mengubah karakteristik dan mengganggu aktivitas sungai, sehingga area pekerjaan pilar di sisi sungai menjadi terbatas. Pada saat kondisi banjir, air sungai meluap sehingga pilar-pilar tersebut terendam yang beresiko terjadinya gerusan lokal terhadap pilar.
Dengan adanya permasalahan tersebut, maka memunculkan ide untuk membuat alternatif desain jembatan pada tugas akhir ini. Jembatan direncanakan dengan konfigurasi kabel arah melintang dengan Double Vertical Plane System dan konfigurasi kabel arah memanjang berupa Fan Pattern System. Jembatan didesain dengan bentang 180 meter, tinggi pylon 60 meter dari tanah, dan lebar 35 meter. Material penyusun struktur lantai kendaraan direncanakan menggunakan Steel Box Girder. Sedangkan pylon menggunakan material beton bertulang berjumlah dua berbentuk A pada tiap ujung jembatan. Permodelan jembatan menggunakan program bantu analisa struktur CSI Bridge. Alternatif desain perencanaan jembatan gumayang akan menggunakan Surat Edaran Menteri Pekerjaan Umum No. 08/SE/M/2015 tentang Pedoman Perencanaan Teknis Jembatan Beruji Kabel, SNI 1725-2016 untuk pembebanan jembatan, SNI 2833-2016 terhadap beban gempa, RSNI-T-02-2004 untuk perencanaan struktur beton untuk jembatan.
Hasil dari alternatif desain ini adalah bangunan atas dan bangunan bawah yang akan disajikan dalam bentuk gambar. Pada permodelan struktur utama digunakan Analisa pembebanan statis dan dinamis. Metode pelaksanaan untuk alternatif desain ini menggunakan metode Incremental Launching dengan program bantu CSI Bridge.

Gumayang Bridge is a bridge located on the Semarang-Demak Toll Road STA 19+600. The Gumayang Bridge has a length of 125 meters and a width of 35 meters which is divided into 3 spans, each span has a different span, namely 31 meters, 47 meters and 47 meters. The superstructure of the Gumayang Bridge is supported by 4 pillars. The Gumayang Bridge will be constructed with 14 PCI girder structures. The problem with this bridge is that the construction must not change the characteristics and interfere with river activities, so that the pillar work area on the river side is limited. During flood conditions, river water overflows so that the pillars are submerged which is at risk of local scouring of the pillars.
With these problems, it gave rise to the idea to create an alternative bridge design in this final project. The bridge is planned with a transverse cable configuration with a Double Vertical Plane System and a longitudinal cable configuration in the form of a Fan Pattern System. The bridge is designed with a span of 180 meters, a pylon height of 60 meters from the ground, and a width of 35 meters. The building material for the vehicle floor structure is planned to use Steel Box Girder. While the pylon uses reinforced concrete material in the form of two A-shaped at each end of the bridge. The bridge modeling uses the CSI Bridge structural analysis tool. The alternative design for the gumayang bridge will use the Circular of the Minister of Public Works No. 08/SE/M/2015 concerning Guidelines for Technical Planning of Cable Tested Bridges, SNI 1725-2016 for bridge loading, SNI 2833-2016 for earthquake loads, RSNI-T-02-2004 for planning concrete structures for bridges.
The result of this alternative design is the upper building and the lower building which will be presented in the form of images. In the main structure modeling, static and dynamic loading analysis is used. The implementation method for this alternative design uses the Incremental Launching method with the CSI Bridge program.
