Abstract
The performance analysis of a building structure under inelastic conditions consisted of static and dynamic methods, which each divided into linear and non-linear categories. The performance-based analysis was included in the non-linear static category and described in the Applied Technology Council (ATC)-40, Federal Emergency Management Agency (FEMA) 273, FEMA 356, and FEMA 440. In this study, some structural open frame models were assessed to determine the structural performance level. The aim of this study was to compare the performance of the open frame building structural models using pushover analysis based on SNI-1726-2002, SNI-1726-2012, and ATC-40 codes. The structural element properties were modeled based on SNI-1726-2002 to represent the buildings previously constructed before the application of SNI-1726-2012. The results showed that the open frame structural models analysed based on SNI-1726-2012 code, had a lower performance points and structural performance levels compared to their counterpart models which were analysed based on SNI-1726-2002 code. Other models showed the opposite behavior due to differences in the characteristics of seismic zones, represented by the response spectrum curves in the SNI-1726-2002 and SNI-1726-2012 codes.
Highlights
The building structure analysis comprises of static and dynamic methods, with each consists of linear and nonlinear categories
The performance-based analysis is included in the non-linear static method and described in the Applied Technology Council (ATC)-40, Federal Emergency Management Agency (FEMA) 273, FEMA 274, FEMA 356, FEMA 440, National Earthquake Hazards Reduction Program (NEHRP) Guidelines for the Seismic Rehabilitation of Building, and Structural Engineers Association of California (SEAOC)'s Vision 2000: Performance-Based Seismic Engineering of Buildings (1995)
The structural models were deformed into inelastic condition due to earthquake loads by developing plastic hinges on the beam and column ends
Summary
The building structure analysis comprises of static and dynamic methods, with each consists of linear and nonlinear categories. The performance-based analysis is included in the non-linear static method and described in the Applied Technology Council (ATC)-40, Federal Emergency Management Agency (FEMA) 273, FEMA 274, FEMA 356 (the FEMA 273 language code), FEMA 440 (the enhancement of FEMA 356), National Earthquake Hazards Reduction Program (NEHRP) Guidelines for the Seismic Rehabilitation of Building, and Structural Engineers Association of California (SEAOC)'s Vision 2000: Performance-Based Seismic Engineering of Buildings (1995). The aim of this study was to determine the performance points and structural performance levels of open frame structures designed using the previous Indonesian earthquake code [2] compared the analysis and results by using the previous [2] and current [3] Indonesian earthquake codes.
