Evaluasi Perhitungan Bangunan atas Jembatan di Proyek Pembangunan Jembatan Sei Pare-Pare Kecil Indra Pura Jalan Lintas Sumatera

Abstract

Evaluation of this bridge uses reinforced concrete and Girder construction using type I with prestressed systems that refer to SNI 1725: 26 (loading regulations for bridges) and RSNI T-12-2004 (planning concrete structures for bridges). The aim is to observe, discover, and evaluate the calculation of the structure of the bridge that has been carried out in the project by calculating the structure of the bridge in accordance with SK SNI 03-2874- 2002, SNI T-12-2004, Loading for Bridges (SNI 1725: 2016). The planned bridge has a total span length of 30.6 meters. The problem taken is the evaluation of the upper structural elements. Evaluation of the structure of the bridge includes floor slabs, sidewalks, back posts, stamped plates, prestressed beam I, and diaphragm. The plan includes bending, shear, torque reinforcement. The analyzed load includes fixed load, traffic load, brake force load, pedestrian load, temperature, wind load, and earthquake load. From the evaluation results, a variety of dimensions and reinforcement results for each structural element which in the analysis meets the structural strength and safety requirements. For vehicle floor slabs used 270 mm thick plate, railing pole has a thickness of 250 mm, height of 1300 mm, the sidewalk has a thickness of 500 mm, the diaphragm has a width of 1160 mm, height 1250 mm, and 150 mm thick, and girder uses PCI girder Post- Tension.
