Kata kunci: Pushover analysis, level kinerjastruktur, ATC-4 ABSTRACT In Indonesia, the challenge faced in the construction of multi-storey buildings is the threat of natural disaster risk in the form of earthquakes. To face the challenges of earthquake risk in high rise buildings, there are several structural strengthening methods, one of which is the use of the core wall structure. Core Wall is a core wall structure that functions as a building stiffness and usually serves also as a place to lift the elevator and emergency stairs Punch over analysis is a means to provide solutions based on Performance Based Seismic Design which in essence is to look for structural capacity. The pushover analysis procedure is carried out by placing a static load in the lateral direction which is increased incrementally until it reaches a certain displacement target or reaches a collapse. In this final task, the author will evaluate a multi-storey building, in this case a 34-storey apartment building that uses a core wall structure as a structural reinforcement. Evaluation is carried out on the seismic performance of the structure in the use of core walls in apartment buildings using pushover analysis. Capacity Spectrum Method (CSM) is one of the ways to find out the performance of a structure. In this non-linear pushover static analysis a capacity curve is obtained which is then further processed by the Capacity Spectrum method The result of a static pushover analysis is a pushover curve that shows the relationship between the Base Shear force and the Roof Displacement. These relationships are called curvature structures. From the analysis process, we get the capacity curve which is the relationship between the movement of reference points on the roof (D) with the basic shear force (V). The results of pushover analysis using SAP2000 v.20 ATC-40 capacity spectrum method shows the value of the roof drift ratio of 0.0025 m for PPUSHX and as much as 0.0028 m for PPUSHY, by looking at the requirements of the ATC-40 for the maximum drift ratio not exceeding the value of 0.001, the level of structure performance the building is at the level of Immediate Occupancy (IO). Building structure has a performance, it means that when the structure receives earthquake load, the building has no significant damage to the structural elements. Stiffness and strength of the building are almost the same as the initial conditions before the structure is affected by earthquake forces. Keywords: Pushover analysis, structure performance level, ATC-40
