Evaluasi dan Analisis Struktur Beton pada Jembatan Kalikuto di Ruas Jalan Tol Batang Semarang

Abstract

The structural strength of a bridge is critical for the safety and security of road users, particularly on toll roads. The existing concrete structure must be evaluated on a regular basis as part of the bridge's health inspection. The concrete structure of the Kalikuto Bridge, which is part of the Batang Semarang Toll Road, is evaluated and analyzed in this study. The combination of destructive and non-destructive tests (DT and NDT), such as mapping concrete strength using a core drill and hammer test, concrete density with Ultrasonic Pulse Velocity (UPV), and reinforcement configuration using a rebar scanner. Meanwhile, the carbonation and corrosion of concrete materials were also evaluated. The finite element method software was used to analyze the concrete tensile strength against anchor pullout. Overall, the structural condition of the Kalikuto Bridge is still very good for land transportation routes until the building's design service life, i.e. compressive strength according to specifications, concrete density about 4356.67 – 5275.33 m/s, rebar configuration according to as built drawing, no carbonation and no corrosion in more than 90% of the structure. Anchor pullout will not occur since the tensile force does not exceed simulation results. Periodic maintenance is required to protect the bridge structure from things that can reduce the concrete strength.
