ABSTRAKJembatan rangka batang canai dingin pejalan kaki merupakan jembatan yang terdiri dari batang-batang profil yang terhubung berbentuk segitiga dan dominan menerima gaya tarik atau tekan, serta ditujukan khusus untuk pejalan kaki dan kendaraan ringan. Penelitian ini bertujuan untuk mengkaji tentang perancangan jembatan pejalan kaki tipe dek bawah menggunakan material canai dingin berdasarkan Standar Nasional Indonesia (SNI) 7971:2013 dan Eurocode 3 dengan menggunakan program SAP2000. Hasil perancangan awal didapatkan profil 2C95x64x2 untuk gelagar memanjang dan melintang, batang vertikal dan horisontal, serta profil 2C95x70x2 untuk batang diagonal. Hasil analisis program SAP2000 menunjukkan bahwa jembatan rangka batang tipe dek bawah memiliki nilai lendutan sebesar 1,1 mm. Berdasarkan hasil analisis didapatkan bahwa rasio beban terhadap kapasitas penampang batang tarik dan batang tekan jembatan rangka batang tipe dek bawah bernilai 0,426 dan 0,445 untuk Eurocode 3, sedangkan untuk SNI 7971:2013 bernilai 0,602 dan 0,545Kata Kunci: jembatan rangka batang, canai dingin, pejalan kaki, dek bawah, SNI 7971:2013, Eurocode 3 ABSTRACKPedestrian cold formed truss bridge consists of connected profile members in a triangular shape and predominantly transfer tensile or compressive forces, and specifically intended for pedestrians and light vehicles. This research intends to examine the design of lower deck pedestrian cold formed bridge based on the Indonesian National Standard (SNI) 7971: 2013 and Eurocode 3 using the SAP2000 program. Preliminary design results obtained 2C95x64x2 profiles for longitudinal and transversal girders, vertical and horizontal members, and 2C95x70x2 profiles for diagonal members. The result of SAP2000 program analysis shows that the deflection of lower deck truss bridge is 1.1 mm. Based on the results of the analysis, it obtained that the ratio of the load to the tension and compression cross-sectional capacity of the lower deck truss bridge is 0.426 and 0.445 for Eurocode 3, while for SNI 7971:2013 is 0.602 and 0.545.Keyword: truss bridge, cold formed, pedestrian, lower deck, SNI 7971:2013, Eurocode 3
