Analisis Kapasitas Box Girder Dengan Tipe Penampang Yang Berbeda

---

ABSTRACT
In the construction of the Trans-Sumatra Toll Road, Rengat–Pekanbaru Section,
specifically at the Pekanbaru Ring Road segment Sta. 193, two identical bridges
are planned to employ prestressed concrete box girder structures. The construction
of these bridges adopts the balanced cantilever method. Implementation of the
balanced cantilever technique requires optimization through cross-sectional
variation of the girder to reduce loading during the construction stages. This study
aims to analyze the capacity of the box girder under various cross-sectional
configurations, taking into account the contribution of the concrete section,
tendons, and reinforcement bars. Capacity analysis begins with the determination
of internal forces acting on the box girder, both longitudinally and transversely,
utilizing MIDAS CIVIL 2022 software. The loading parameters refer to SNI
1725:2016 for live and dead loads and SNI 2833:2019 for seismic design
considerations. The prestressing force analysis indicates a loss of prestress
amounting to 19.94%, equivalent to 272.18 MPa. The resulting stress and deflection
values in each box girder segment satisfy the allowable limits specified in RSNI T-
12-2004. In the calculation of the capacity for the support segment, the results
obtained were a bending moment capacity of 1.20×106 kN.m; shear 4.70×104
kN.m; and a torque moment of 3.36×104 kN.m. Meanwhile, for the field segment,
the box girder capacity was found to include: bending moment 2.49×105 kN.m;
shear 2.16×104 kN.m; and a torque moment of 1.77×104 kN.m. Based on the
analysis, the reinforcement configuration in the design of the Siak Bridge at Sta.
193 generally meets the required capacity to resist ultimate loads. However, the
interaction diagram analysis suggests that additional transverse reinforcement is
needed in the web region to enhance structural performance.
