Earthquake mitigation for infrastructure, especially bridges, needs to be done to avoid collapse of the bridge structure under earthquake load. The investigation and rehabilitation of existing bridges against earthquake hazards needs to be carried out through a screening process based on The Bridge Inspection Guidelines (Pd No.005-01/P/BM/2011). Based on the results of the inspection and the screening process, it can be determined whether the bridge is able to resist earthquake loads during its service lifetime or needs to be strengthened. This study aims to determine the strength capacity of Harbour Road bridges in resisting earthquake loads based on SNI 2833 2016 and Peta Gempa Nasional 2017 during its service lifetime. Analysis of the pushover structure was carried out at Pierhead 231 which is located on the WiyotoWiyono Harbour Road,Jakarta. The modeling of Harbour Road bridge structure in longitudinal direction consists of piers and concrete girder separated by expansion joint and bearing, while in transverse direction is modeled as a single pier system. Structural analysis modeling is assumed to behave as a system with single degree of freedom (SDOF). Based on the results of pushover analysis, it can be seen the location and level of plastic hinge that occur when the performance point is reached. During design earthquake conditions, the performance point is obtained in the Immediate Occupancy condition and the plastic hinge occurs first at the bottom of the Pier. Structural performance at the time of the earthquake design is still under life safety conditions so the Harbour Road bridge still meets the strength requirements.
