EVALUASI STRUKTUR TAHAN GEMPA PADA BANGUNAN GEDUNG GOLD COAST OFFICE JAKARTA UTARA
AbstractIndonesia is a country that is in an active tectonic zone because three large and small plates meet, namely the Indo-Australian plate, the Eurasian plate, and the Pacific plate, so Indonesia is a zone prone to earthquakes. The Gold Coast Office building, with coordinates -6.102458°.106.739800°, is located on Kapuk Island, North Jakarta. It has a building area of 129,862 m2 and a building height of 125.8 m. The research on the evaluation of earthquake-resistant structures aims to determine the structural performance of the Gold Coast Office Building based on the parameters of base shear, mass participant ratio, and displacement. The results of the study were used to determine the performance evaluation of the structure based on service limit performance and ultimate limit performance. The dynamic analysis of the response spectrum method based on SNI 1726-2019 (2019) was used as the method of this research. The displacement value due to the influence of the planned earthquake in the X direction max is 0.0085 m and in the Y direction max is 0.0086 m. It can be stated that the Gold Coast Office North Jakarta building is safe and meets the performance requirements for building structures based on service limit performance with requirements (0.03/R)*H = 0.0176. The displacement value due to the influence of the planned earthquake in the X direction max is 0.0418 m and in the Y direction max is 0.0419 m, so it can be stated that the Gold Coast Office North Jakarta building is safe and meets the performance requirements for building structures based on ultimate limit performance with requirements (0.02*H) = 0.082 m.
