Abstract

Indonesia terletak pada pertemuan 3 lempeng tektonik besar dunia, sehingga menjadikan Indonesia sebagai negara rawan gempa bumi. Peraturan desain bangunan tahan gempa di Indonesia saat ini menggunakan desain berbasis gaya. Dalam perkembangannya, mulai diperkenalkan konsep Performance Based Design (PBD) yang memanfaatkan teknik analisa non-linier berbasis komputer dengan mengadopsi perpindahan struktur. Pada tugas akhir ini, gedung Apartemen Grand Sungkono Lagoon Tower Caspian Surabaya dengan kondisi tanah lunak didesain ulang setinggi 20 lantai dan 1 basement dengan menggunakan struktur dual system berdasarkan konsep PBD. Pendekatan PBD yang digunakan untuk menentukan base shear desain adalah Direct Displacement Based Design (DDBD). Profil perpindahan DDBD direpresentasikan sebagai derajat kebebasan tunggal (SDOF) dengan parameter daktilitas dan equivalent viscous damping. Untuk memvalidasi hasil desain DDBD, dievaluasi dengan pushover analysis dengan ETABS 2016 sehingga dapat diketahui tingkat kinerja berdasarkan FEMA 356 dan FEMA 440. Dari hasil perhitungan base shear dengan pendekatan DDBD didapatkan 6695,31 kN dengan displacement rencana 0,682m untuk arah x-x dan 9234.27 kN dengan displacement rencana 0,773m untuk arah y-y, dengan level kinerja rencana Life Safety (drift = 0,02). Nilai target displacement hasil pushover analysis berdasarkan dokumen FEMA 356 dan FEMA 440 adalah 0.531m, 0.471m untuk arah x-x dan 0.613m, 0.681m untuk arah y-y. Sehingga, kinerja bangunan berada di kategori Immediate Occupancy (IO). Dapat disimpulkan bahwa anlisis dengan metode DDBD efektif sebagai alternatif desain berbasis gaya. ================================================================================================ Indonesia is located at the confluence of 3 major tectonic plates of the world, makes Indonesia prone to disaster, especially earthquake. Today, the regulations for earthquake resistant building designs in Indonesia use force based design. In the development of building design, the concept of performance-based design has now begun, which utilizes computer-based non-linear analysis techniques, this concept adopts structural displacement model. In this final project, the apartment building of the Grand Sungkono Lagoon Apartment, Caspian Tower stands on soft ground in Surabaya and will be redesigned as high as 20 floors and 1 basement using a dual system structure system based on the performance-based design concept. The approach used to determine the design base shear is Direct Displacement Based Design (DDBD). DDBD displacement profile is represented as a single degree of freedom (SDOF) with ductility parameters and equivalent viscous damping. To validate the DDBD design results, it was evaluated by pushover analysis with ETABS 2016 to determine the level performance based on FEMA 356 and FEMA 440. The results of base shear calculation using the DDBD approach are 6695.31kN with displacement of 0.682m for x-x direction; 9234.27 kN with displacement of 0.773m for y-y direction; and performance level of Life Safety plan (drift =0.02). The displacement target value of the pushover analysis based on the FEMA 356, FEMA 440 documents are 0.531m, 0.471m for the x-x direction; 0.613m, 0.681m for the y-y direction. Thus, building performance is in Immediate Occupancy (IO) category. It can be concluded that analysis with DDBD method is as effective as an alternative force based design
