Studi Penggunaan Link Slab Pada Jembatan Komposit Bentang 14 & 18 m
Abstract
Abstrak
Pada umumnya, banyak jembatan di indonesia yang masih menggunakan sistem perletakan sederhana dimana struktur antara abutment dengan lantai kendaraan, maupun lantai kendaraan dengan lantai kendaraan terpisah dan ditutup dengan sebuah konstruksi yang dinamakan dengan Expansion Joint. Munculnya siar pada pembangunan jembatan tentunya memberikan beberapa permasalahan, diantaranya korosi yang mampu merusak struktur jembatan sehingga dapat mengurangi usia jembatan dan dngan penggunaan jembatan seperti Expansion Joint memberikan rasa ketidaknyamanan pada pengguna jalan. Pada studi ini, siar yang ada akan dihubungkan dengan menggunakan metode baru, yakni dengan menggunakan konstruksi lantai terus menerus menggunakan penghubung Link Slab. Studi ini akan dilakukan pada jembatan komposit dengan bentang 14 m dan 18 berdasarkan aturan Standar Bangunan Atas Jembatan komposit dari Direkorat Bina Program Jalan Direktorat Jenderal Bina Marga Departemen Pekerjaan Umum dan SNI 1725-2016. Hasi dari studi penggunaan link slab pada stuktur jembatan komposit ini yakni memperoleh panjang link slab, panjang debonding zone pada link slab, tebal link slab, pengaruh rotasi pada panang link slab, serta pengaruh penulangan pada link slab.
Kata kunci: Jembatan Komposit, Expansion Joint, Link Slab, Penulangan Link Slab.
Abstract
In general, many bridges in Indonesia still use a simple laying system where the abutment and the vehicle floor, as well as the vehicle floor with the vehicle floor are separated and closed with a construction built with Expansion Joints. The emergence of bridge broadcasting certainly presents several problems, including corrosion that is able to utilize bridges so that they can reduce bridges and with the use of bridges giving road users a sense of belonging. In this study, the existing broadcasters will use a new method, namely by using a continuous floor using a Link Slab connector. This study will be carried out on composite bridges with spans of 14 m and 18 based on the rules of the Composite Bridge Superstructure Standard from the Directorate General of Highways Road Development Program of the Ministry of Public Works and SNI 1725-2016. The results of the study using the link slab in this composite bridge structure were to obtain the length of the link slab, the length of the debonding zone on the link slab, the thickness of the link slab, the effect of rotation on the link slab length, and the effect of reinforcement on the link slab.
Keywords: Composite Bridges, Expansion Joint, Link Slab, Reinforcement of Link Slab.
