Abstract
Under major load earthquakes, reinforced concrete structures designed according to the current codes will experience an inelastic deformation which is difficult to predict and control. Performance-based plastic design (PBPD) methodology is applied forward to design reinforced concrete structures in this study. In this method, as performance criteria, the target drift and yield mechanisms are preselected. Based on the work-energy balance principle, the design base shear is given as earthquake level and calculated as work required to push the structure as monotonically load to the target drift. The load equals the energy needed by an equivalent single degree of freedom in the same state. The plastic design is utilized to design the desired yield mechanism. The method was adopted on a 10-story reinforced concrete structure with an earthquake load in lateral forces based on SNI 1726:2019 and the Performance-Based Plastic Design (PBPD) method. Pushover analysis was carried out where the structure was pushed to obtain lateral load resistance followed by yielding gradually until plastic deformation occurred collapse From the pushover analysis, the ductility value for SNI 1726:2019 is less ductile than analytical using the Performance-Based Plastic Design (PBPD) method
Highlights
Important buildings such as schools, hospitals, office buildings, and even shopping centers in SNI 1726:2019 [1] are included in priority factor IV
Performance-based seismic design (PBSD) is an iterative process in which the designer begins by setting performance objectives, followed by an initial design, analyzing the initial design whether it is following the performance targets, and redesign and reassessment are carried out if necessary until the desired performance level is achieved [2][3]

Summary
Important buildings such as schools, hospitals, office buildings, and even shopping centers in SNI 1726:2019 [1] are included in priority factor IV. By providing an earthquake value more significant than the planned earthquake, these important buildings are expected to have an operational performance level during a moderate earthquake They have an immediate occupancy performance level during a large earthquake (MCE) to reduce the risk of fatalities after a building collapse when an earthquake occurs. PBSD is an iterative process in which the designer begins by setting performance objectives, followed by an initial design, analyzing the initial design whether it is following the performance targets, and redesign and reassessment are carried out if necessary until the desired performance level is achieved [2][3] The flow of this method starts from choosing the desired performance level, designing according to the performance level, and after the design is completed, the design target can become acceptance criteria through performance evaluation for the performance target level set by FEMA 356.
