This research measures the effect of increasing Ss by 0.1g on 10 and 30 storey building structures in DIY. The parameters measured include frequency, story drift, p-delta influence, stiffness and stability index in 7 sub-districts in DIY using equivalent static earthquake analysis and response spectrum variance analysis. The frequency of 10 and 30 storey buildings in the first 3 modes is less than 1 Hz. This frequency is below the peak acceleration frequency of the DIY earthquake which was measured in the range of 1.25 Hz to 7.14 Hz in the 7 sub-districts studied. The frequency of earthquake vibrations in DIY is more dangerous for low to medium storey buildings or buildings with a period (T) of less than 0.8 seconds. An increase in Ss of 0.1g in a 10-story building resulted in the earthquake force distribution increasing by 3.99% in the x and y directions, story drift increasing by 4.12% in the x and y directions, p-delta increasing by 0.46% in the x and 0.28% in y direction, rigid structure, each floor is a swaying portal. Meanwhile, in a 30-story building, the earthquake force distribution increased by 6.24% in the x and y directions, story drift increased by 6.27% in the x direction and 5.31% in the y direction, p-delta increased by 0.15% in the x direction and 0.55% in y direction, rigid structure, each floor is a swaying portal.. \u0000 ","PeriodicalId":518980,"journal":{"name":"JURNAL TEKNIK SIPIL UKRIM","volume":"74 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140528930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
