Abstract

Gedung Hotel Grand Mercure Malang merupakan gedung beton bertulang 16 lantai dan 1 lantai atap dengan struktur sistem ganda yaitu Sistem Rangka Pemikul Momen Khusus (SRPMK) dan dinding geser yang mengacu pada peraturan SNI 1726-2012. Akibat adanya pembaharuan peraturan SNI 1726-2019 yang terdapat perubahan nilai respons spektrum sehingga dapat mempengaruhi beban gempa yang terjadi. Oleh karena itu, struktur gedung tersebut perlu dilakukan evaluasi struktur pada sistem struktur bangunan eksisting. Apabila terdapat beberapa kegagalan dalam sistem struktur maupun kegagalan elemen struktur, maka dilakukan penambahan peredam gempa fluid viscous damper dan CFRP. Analisis struktur dilakukan dengan tiga tahap analisis, yaitu analisis struktur tahap 1 (kondisi eksisting dengan peraturan awal SNI 1726-2012); analisis struktur tahap 2 (kondisi eksisting dengan peraturan baru SNI 1726-2019); dan analisis struktur tahap 3 (struktur eksisting ditambahkan peredam gempa fluid viscous damper dengan peraturan SNI 1726-2019). Hasil dari analisis struktur tahap 3 setelah ditambahkan peredam memberikan dampak yang signifikan dari periode fundamental struktur, gaya geser dasar, maupun simpangan antar lantai. Periode struktur pada analisis struktur tahap 3 sebesar 1,275 detik, periode tersebut mengalami penurunan sekitar 62% dari kondisi struktur eksisting. Simpangan antar lantai pada analisis struktur tahap 3 tidak ada yang melebihi simpangan izin untuk arah sumbu X maupun arah sumbu Y. Meskipun struktur gedung telah diperkuat menggunakan FVD, masih terdapat elemen struktur balok yang mengalami kegagalan akibat geser namun jumlahnya berkurang sebanyak 78% yaitu sebanyak 54 balok yang gagal dibandingkan dengan sebelum diperkuat menggunakan FVD. Elemen struktur balok yang gagal tersebut diperkuat menggunakan Carbon Fiber Reinforced Polymer. ======================================================================================================= Hotel Grand Mercure Malang building is a 16-story reinforced concrete building and a roof floor with a dual system structure, namely special moment resisting frame system (SRPMK) and shear walls that refer to SNI regulations 1726-2012. As a result of the renewal of SNI regulations 1726-2019, there is a change in the value of the response spectrum so that it can affect the burden of earthquakes that occur. Therefore, it is necessary to evaluate the structure of the existing building structure system. If there are several failures in the structural system or structural element failures, it can be added earthquake absorbers, namely fluid viscous damper and CFRP. Structural analysis was carried out in three stages of analysis, namely, stage 1 structural analysis (existing conditions with the initial regulations of SNI 1726-2012); structure analysis stage 2 (existing conditions with new regulations of SNI 1726-2019); and stage 3 structural analysis (the existing structure that added with a fluid viscous damper with the regulations of SNI 1726-2019). The results of the structural analysis in stage 3 after adding dampers have a significant impact on the fundamental period of the structure, the base shear force, and the drift between floors. The period of the structure in stage 3 of the structural analysis is 1.275 seconds, this period has decreased by about 62% from the condition of the existing structure. There is no deviation between floors in stage 3 structural analysis that exceeds the allowable deviation for the X-axis direction and the Y-axis direction. Although the building structure has been reinforced using FVD, there are beam structural elements that still fail due to shear but the number is reduced by 78%, which is as many as 54 blocks that failed compared to before strengthened using FVD. The failed beam structural elements were reinforced using Carbon Fiber Reinforced Polymer.
