Abstract

 To accommodate the rapid development of residential and commercial areas in the Bumi Serpong Damai (BSD) Region, Banten, the construction of the Kadisurung bridge is necessary to integrate road networks. Before being operational to ensure the safety of bridge users, load testing is conducted. Parameters that must be met in the testing include not exceeding the strain and deflection limits during operational conditions, including when maximum loading occurs. To assess the bridge's performance during operation, research was conducted on both sides of the central span (western side bridge, JSB, and eastern side bridge, JST) with static load testing carried out with gradually increasing loads up to 50% UDL (136 tons), followed by gradual load removal. At JSB, the maximum deflection at 100% UDL, estimated from the deflection at 50% UDL, was 39.92 mm, and at JST, it was 31.67 mm, while the allowable deflection was 43.3 mm. Based on the deflection parameters, the relative capacities of JST and JSB are expressed as 108.5% and 136.7% respectively, relative to their allowable capacities. This indicates that the estimated bridge capacity using static load testing parameters is 6%-10% greater than when using parameters from dynamic load testing. Thus, the bridge is deemed suitable for operation.

Abstract

Jembatan dan terowongan jalan merupakan salah satu prasarana transportasi yang menyangkut hajat hidup orang banyak dan mempunyai fungsi sosial yang sangat penting sehingga harus dilakukan penyelenggaraan keamanan bagi pengguna jalan. Sebelum sebuah jembatan difungsikan harus dilakukan pengujian, untuk memastikan tingkat keselamatan dan keamanan jembatan. Pengujian pembebanan dinamik (uji getar) bertujuan untuk mendapatkan parameter dinamik seperti frekuensi alami, rasio redaman, kekakuan dan pola getar, sebagai salah satu indikator untuk menilai kelaikan fungsi jembatan. Hasil uji getar, baik sisi barat (JSB) maupun sisi timur (JST) menunjukkan performa yang baik dengan frekuensi alami JSB 4.093 Hz dan JST 4.956Hz lebih tinggi dari pendekatan teoritik yaitu 4.002 Hz. Hal ini menunjukkan bahwa kekakuan aktual lebih tinggi dibandingkan teoritisnya. Rasio redaman aktual JSB 2.138% dan JST 2.883%, nilai tersebut masuk katagori beton utuh. Berdasarkan penilaian parameter dinamik, jembatan dinyatakan laik fungsi
