Comparison of base shear at low rise building in Cupuwatu, Yogyakarta with response spectrum method based on SNI 1726-2012 and SNI 1726-2019.

The design standard update that has been issued by BSN from SNI 1726-2012 to SNI 1726-2019 gives some influence on the calculation of earthquake-resistant building design. The influence given includes internal forces, strength, and resistance. This study was conducted to evaluate the effect of updating code for building design planning on the effect of the base reaction that occurs. The research was conducted using an analytical method with reference to as-build drawings, the results of a land survey in the field, and some of the latest regulations regarding the planning of earthquake-resistant buildings in Indonesia. The analysis was carried out in a low-rise building located in Cupuwatu, Yogyakarta. Structural modelling is modelled with a 3D frame by accepting earthquake loads which are modelled statically and dynamically using a response spectrum. The difference from SNI 1726-2012 to SNI 1726-2019 case study in Cupuwatu, Yogyakarta does not give too significant difference to the calculation of output in the form of base reaction, although there are differences in the value of the response coefficient spectral acceleration parameter in the short period and the response spectral acceleration parameter in the one second period. and long-period transition periods. The difference that occurs is 0.07% in the x direction and 0.1% in the y direction in the intact section and 0.06% in the x direction and 0.13% in the y direction in the cracked section.
