Comparative study of internal force in lecture buildings in Daerah Istimewa Yogyakarta between SNI 1726-2012 and 1726-2019 with the spectrum response method (2D)

Abstract

An earthquake is a sudden movement of the ground that comes from a wave in a place and spreads in all directions. In 2019 the Government of Indonesia has ratified a new standard on procedures for earthquake resistance planning for building and non-building structures, namely SNI 1726: 2019 as a revision of SNI 1726: 2012. The adoption of SNI 1726-2019 as a new standard has changed the scope of the procedure for calculating earthquakes to become wider so that it can follow the current developments. Earthquake loads on buildings were analyzed using dynamic response spectrum analysis. This study aims to compare the results of the calculation using the response spectrum using SNI 1726-2012 and SNI 1726-2019 in order to determine the safety of building that still use the old rules. The building structure is modeled on a lecture building with a height of 14,10 m in the Province of D.I Yogyakarta. The results of the research prove that the structure of the lecture building which still uses the old method must be rehabilitated so that it is able to withstand earthquake loads based on the new SNI 1726-2019 method. This occurs due to the discovery of new faults in Indonesia.
