As has happened in various cases of earthquakes, the impact caused by each earthquake event varies, because the earthquake shaking that occurs on the ground is not only influenced by the distance and strength of the earthquake, but also by local soil conditions which are related to the amplification phenomenon. earthquake waves are influenced by the type and thickness of the soil/sediment layer above the bedrock. Reinforced concrete storey buildings are designed to withstand both vertical and horizontal loads. The taller the building, the greater the lateral load that will be received by the building structure. In the design of earthquake-resistant structures, the inelastic behavior of the structure is highly expected for the occurrence of earthquake energy dispersion during both moderate and strong earthquakes. In earthquake-prone countries such as Indonesia, it is required to comply with applicable national standards and the structure can still function and be safe from earthquakes affected by the earthquake. The purpose of this study was to determine how much influence the type of soil has on the lateral displacement of a 10-story reinforced concrete building using shear walls in accordance with earthquake building regulations (SNI 1726, 2019) and loading (SNI 1727, 2020). The results obtained that soft soil types have the largest deviation value with a value of 91,831 mm and hard rock soil types have the smallest deviation value with a value of 44,114 mm.

Pada studi ini dilakukan analisis terhadap kinerja struktur bangunan baja bertingkat (5 dan 15 lantai) dengan 3 variasi tipe pengaku diagonal (Inverted V, Single Diagonal dan X-Bracing) dan gedung terbuka. Analisis dilakukang dengan bantuan software SAP 2000 v14. Hasil dari analisis ini akan dibandingkan dari 4 tipe gedung dan 2 jenis ketinggian. Melalui studi analisis ini dilakukan perbandingan perpindahan dan simpangan masing-masing gedung. Gedung dengan tambahan pengaku diagonal memiliki nilai perpindahan yang lebih kecil dibanding struktur gedung terbuka. Gedung dengan tipe pengaku diagonal X-Bracing mampu mereduksi perpindahan paling besar dengan presentase 30,78% untuk gedung 5 lantai dan 18,84% untuk gedung 15 lantai. Taraf kinerja struktur bangunan 5 lantai termasuk dalam Immediate Occupancy untuk semua variasi pengaku diagonal. Hal ini menunjukkan bahwa penggunaan tipe pengaku diagonal X-Bracing paling efektif dapat meningkatkan kekakuan, kekuatan dan stabilitas struktur.
