Muhamad, Gunawan (2018) Kapasitas Ketahanan Gempa Rumah Tinggal 2 Lantai Di Kota Malang Menggunakan Metode Wall Density Index. Sarjana thesis, Universitas Brawijaya.
Abstract
Malang merupakan salah satu daerah di Indonesia yang sering mengalami gempa. Sebagian besar kerusakan akibat gempa terjadi pada gedung non struktur yaitu rumah tinggal yang dibangun tanpa ada perencanaan. Kerusakan yang terjadi mengakibatkan kerugian material hingga korban jiwa. Perlunya kajian mengenai desain rumah tinggal serta kapasitas ketahanan gempa rumah tinggal untuk mengetahui ketahanan rumah tinggal apabila terjadi gempa. Pada kajian ini menggunakan metode wall density index yaitu mencari indeks kerapatan dinding berdasarkan pada perbandingan luas dinding pada tiap arah ortogonal dengan luas lantai. Rumah tinggal yang digunakan yaitu rumah tipe 45 extension, 56 dan 56 extension. Data rumah yang digunakan adalah denah dan detail struktur kolom balok dan pelat. Analisis desain rumah dengan menghitung nilai eksentrisitas titik pusat massa rumah terhadap kekakuan dinding dan perbandingan panjang-lebar bangunan. Nilai wall density index (d) di Malang lebih besar dari 4,5%, kontrol kapasitas seismik dengan VRVU⁄≥ 1,6, kontrol kebutuhan wall density index terhadap gaya gravitasi dengan σRσU⁄≥ 2,33 dan kontrol daya dukung dinding dengan PRPU⁄≥ 2,33. Hasil yang diperoleh yaitu desain rumah untuk semua tipe masih diizinkan dengan nilai eksentrisitas tipe 45 extension 0,3675 < 0,3b (1,8), tipe 56 0,381 < 0,3b (1,425), tipe 56 extension 0,433 < 0,3b (1,8). Untuk nilai wall density index dan kontrol kapasitas seismik, kontrol kebutuhan wall density index terhadap gaya gravitasi dan kontrol daya dukung dinding berturut- turut yaitu tipe 45 extension 6,7% > 4,5%, 2,137 > 1,6, 7,827 > 2,33, 3,643 > 2,33. Tipe 56 yaitu 6,32% > 4,5%, 2,366 > 1,6, 6,753 > 2,33, 4,461 > 2,33. Tipe 56 extension yaitu 6,63% > 4,5%, 1,827 >1,6, 9,010 > 2,33, dan 5,944 > 2,33. Kesimpulan yang didapatkan adalah tipe rumah memenuhi kapasitas ketahanan gempa berdasarkan metode wall density index.
English Abstract
Malang is one of many areas in Indonesia that often experience earthquake. Most of the damage caused by earthquake occurred in non-structural buildings, ie low-rise building such as house that built without engineeering planning. The damage that occurred resulted in material loss to casualties. It is necessary to analyze the low-rise building design and the resistant capacity in the event of an earthquake. This study using wall density index method. Wall density index can be obtained as the ratio of the sum of the the cross-sectional wall areas for all walls in the direction being evaluated and area of floor plan. The building used is type 45 extension, 56 and 56 extension. The data used are plan view of a building and detail of the column, the beams and the plates. The low-rise building design for its regularity can be analyzed by calculating the eccentricity of the center of mass building to the stiffness of the wall and the length to width ratio. Wall density index value in Malang should exceeds 4,5% and can be check using seismic safety check where VRVU⁄≥ 1,6, wall density requirements for grafity loads where σRσU⁄≥ 2,33 and load-bearing strength check for critical wall where PRPU⁄≥ 2,33. The results obtainde are the low-rise building design for all types are still allowed with the value of eccentricity for type 45 extension is 0,3675 < 0,3b (1,8), type 56 is 0,381 < 0,3b (1,425), type 56 extension is 0,433 < 0,3b (1,8). The value of wall density index and seismic safety check, wall density requirements for grafity loads, and load-bearing strength check for critical wall as follows. Type 45 extension 6,7% > 4,5%, 2,137 > 1,6, 7,827 > 2,33, 3,643 > 2,33. Type 56 yaitu 6,32% > 4,5%, 2,366 > 1,6, 6,753 > 2,33, 4,461 > 2,33. Type 56 extension yaitu 6,63% > 4,5%, 1,827 >1,6, 9,010 > 2,33, dan 5,944 > 2,33. The conclusion is for all types of the low-rise building meet the need of the capacity resistance based on wall density index method.
