Abstract

Seiring dengan perkembangan teknologi dan meningkatnya kebutuhan akan infrastruktur yang andal, berbagai negara terus memperbarui standar desain jembatan mereka. Di Indonesia, standar desain jembatan yang berlaku saat ini adalah SNI, yang masih mengacu secara dominan pada standar AASHTO. Studi ini bertujuan untuk melakukan perbandingan antara tiga standar internasional yaitu AASHTO, EUROCODE, dan IRC dalam mendesain jembatan tipe Balanced Cantilever dengan menggunakan Midas Civil. Parameter yang dikaji meliputi filosofi desain, jenis pembebanan, faktor keamanan, serta hasil analisis struktur berupa gaya geser, momen lentur, dan deformasi. Perbedaan utama dari ketiga standar terletak pada model moving load. AASHTO menggunakan truk HL-93, EUROCODE menggunakan LM1, sedangkan IRC menggunakan kendaraan tipe 70R. Hasil analisis menunjukkan bahwa EUROCODE secara konsisten menghasilkan nilai tertinggi untuk momen ultimit 2,003,999.82 kNm, gaya geser vertikal 61,193.03 kN dan defleksi maksimum 74.67 mm. Hasil analisis IRC untuk momen, gaya geser dan defleksi berturut-turut adalah 1,963,545.68 kNm, 61,747.15 kN dan 62.79 mm. Model AASHTO menunjukkan hasil terendah untuk momen, gaya geser dan defleksi berturut-turut adalah 1,939,468.54 kNm, 53,597.00 kN dan 32.71 mm. Perbedaan ini terutama disebabkan oleh variasi dalam filosofi perencanaan, kombinasi pembebanan, serta penerapan faktor keamanan di masing-masing standar. Berdasarkan temuan tersebut, disarankan agar Standar Nasional Indonesia (SNI), yang saat ini banyak mengadopsi pendekatan AASHTO, mulai mempertimbangkan integrasi aspek-aspek tertentu dari EUROCODE dan IRC. Langkah ini penting guna meningkatkan reliabilitas desain, khususnya dalam menghadapi tuntutan lalu lintas di masa depan.

With the advancement of technology and the growing demand for reliable infrastructure, many countries continue to update their bridge design standards. In Indonesia, the current applicable standard is SNI, which predominantly refers to the AASHTO standard. This study aims to compare three international standards such as AASHTO, EUROCODE, and IRC in the design of balanced cantilever bridges using Midas Civil software. The parameters evaluated include design philosophy, load types, safety factors, and structural analysis results such as shear force, bending moment, and deformation. The primary distinction among the three standards lies in their moving load models. AASHTO adopts the HL-93 truck, EUROCODE utilizes the LM1 load model, while IRC employs the 70R vehicle type. Analysis results indicate that EUROCODE consistently yields the highest values for ultimate moment at 2,003,999.82 kNm, vertical shear force at 61,193.03 kN, and maximum deflection at 74.67 mm, followed by IRC with corresponding values of 1,963,545.68 kNm, 61,747.15 kN, and 62.79 mm. The AASHTO model produced the lowest results, with moment, shear force, and deflection values of 1,939,468.54 kNm, 53,597.00 kN, and 32.71 mm, respectively. These differences are primarily due to variations in design philosophy, load combination schemes, and safety factor applications unique to each standard. Based on these findings, it is recommended that Standar Nasional Indonesia (SNI), which currently adopts a predominantly AASHTO-based approach, consider integrating selected aspects of the EUROCODE and IRC. Such an approach would enhance design reliability, particularly in addressing the increasing demands of future traffic conditions.
