Pushover Analysis of a Structure in Accordance with the Most Recent and Oldest SNI
摘要
Indonesia’s geographical position is quite vulnerable to earthquakes. The Indonesian government through the National Standardization Agency is trying to update earthquake regulations in Indonesia from SNI 1726:2012 to SNI 1726:2019. This study aims to compare the structural evaluation results of a structure in accordance with SNI 1726:2012 and SNI 1726:2019 and calculate the capacity of A structure using pushover analysis. The calculation results of the design spectra value show that the Sds value has increased by 12.42% and the Sd1 value has decreased by 16.28% from SNI 1726:2012 to SNI 1726:2019. The analysis also showed that the maximum displacement of A structure in the X direction increased by 12.90% (from 0.031 m to 0.035 m) and the Y direction also increased by 12.50% (from 0.016 m to 0.018 m) from SNI 1726:2012 to SNI 1726:2019. In addition, there was also an increase in nominal base shear force by 11.69% (from 618.832 kN to 691.163 kN) from SNI 1726:2012 to SNI 1726:2019. Nevertheless, based on the pushover analysis results, it shows that the structural capacity of A structure is still greater than the static and dynamic loading that occurs. The results of this analysis also show that the structural performance level of a structure is included in the Immediate Occupancy (IO) category.
