Existing Building Evaluation against SNI (Indonesian National Standards) 1726-2019 Concerning Earthquake Resistance Planning Procedures for Building and Non-Building Structures

Abstract

With the issuance of the 2019 SNI 1726-2019 Earthquake Regulations, it is necessary to recalculate the strength of the existing buildings designed with SNI 1726-2012. The building that becomes the case study is a hospital located in Mojokerto City, East Java, Indonesia. This study aims to determine the strength of the existing building against the provisions in SNI 1726-2019. The method of calculation is by evaluating the workload of the foundation, calculating the amount of deviation between levels and the effect of P - Δ that occurs. The building was built in 2018 and designed using the SNI 1726-2012Earthquake Regulations which are based on the 2017 Earthquake Map. The results of the recalculation are: 1. The deviation between levels in the X-direction on the 1^st floor and 2^nd floor is greater than the allowable deviation, while on the 3^rdand 4^th floor it is smaller than allowed. The Y-direction deviation on all floors is smaller than allowable; 2Workload on the foundation at all points of the column with a combination of gravity load and earthquake load is smaller than the allowable bearing capacity.
