Abstract
Performance-Based Plastic Design (PBPD) is a structural analysis that can be used to review structural performance. This method is increasingly popular to be used in the earthquake-prone area. This method is based on energy method that can be applied to steel or concrete structures. Meanwhile, Indonesia has already SNI 1726:2102 to be used as a guide in designing the thrust load to review the level of structural performance. Both of these things need to be used as a reference in areas that were initially considered safe from the earthquake but based on the development of earthquake micro zonation maps, it is very possible to become potential areas that also become earthquake regions. For this reason, the case of the structure that was built in the Pekanbaru area was taken. From the analyses of structural behavior, the structure that applied PBPD has greater displacement than the structures that apply the thrust load of SNI 1726: 2012. The percentage of displacement that occurred was 8-37 %. Based on performance analysis, the structures according to PBPD shows a better level of performance to the application of SNI 1726: 2012 thrust load.
Highlights
The Government of Indonesia, through the Indonesian National Standardization Agency together with national earthquake experts, has set a standard in the planning of buildings that are earthquake-safe
From the analysis of structural responses that have been carried out, it can be concluded as follows: (1) Lateral force for modeling based on Performance-Based Plastic Design (PBPD) is greater than modeling based on SNI 1726: 201 (2) Actual ductility value for structures designed based on Performance-Based Plastic Design (PBPD) is higher compared to structures designed based on SNI 1726: 2012 (3) Percentage of increase in displacement in building structures between 8 - 37%
Based on the graph above, it appears that the displacement that occurs in the structure caused by earthquake loads based on Performance-Based Plastic Design (PBPD) is greater than SNI 1726: 2012
Summary
The Government of Indonesia, through the Indonesian National Standardization Agency together with national earthquake experts, has set a standard in the planning of buildings that are earthquake-safe. This standard is contained in the Indonesian National Standard SNI 031726-2012 concerning Procedures for Planning Earthquake Resilience for Buildings. The PBPD method uses the selection of drift targets and yield mechanisms as base performance constraints. Both of these limits have a direct effect on the level and distribution of building damage. PBPD uses lateral force calculation and refers to the energy balance method so that the value of the energy balance modification factor is obtained
