Abstract

Sebagian wilayah Indonesia terletak tepat di atas sesar gempa aktif, sehingga relatif rentan terhadap gempa bumi. Struktur rumah yang tahan gempa merupakan suatu hal yang harus diambil dalam perencanaan bangunan. Salah satu sistem struktur tahan gempa pada bangunan adalah sistem dinding pemikul (bearing wall), kelebihan dari sistem ini adalah dinding memberikan kontribusi terhadap kekuatan struktur searah bidang (inplane) yang cukup besar. Dalam penelitian ini dilakukan uji siklik pada portal struktur pracetak dengan sambungan mekanis grouting yang diberi pengisi dinding bata ringan (AAC) dengan sambungan antara bata ringan dan komponen struktur diberi lapisan epoxy sebagai pengganti stek tulangan dan diverifikasi dengan model yang dilakukan dengan software Abaqus FEA. Hasil pengujian siklik menunjukkan nilai maksimum beban lateral dorong sebesar 57,28 kN dan beban lateral tarik sebesar 47,56 kN. Hasil uji siklik ini diverifikasi dengan pemodelan numerik. Hasil model Abaqus untuk lateral dorong adalah 56,68 kN (rasio adalah 0,99) sedangkan akibat beban lateral tarik adalah 46,73 kN (rasio adalah 0,98). Hasil pengujian maupun pemodelan Abaqus menunjukkan kapasitas lateral yang mendekati. Kapasitas geser portal struktur (Vkapasitas) yaitu 19,03 kN dimbil dari kondisi tarik maksimum sebesar 47,56 dibagi dengan faktor kuat lebih sistem dinding (Ω0) sebesar 2,5. Hasil analisis perhitungan gaya geser dasar (demand capacity) struktur rumah pracetak 1 lantai dapat diaplikasikan pada daerah dengan SDS ≤ 0,710g (kategori desain seismik “D”), namun dari pola retak dan lepasnya sambungan dinding ke kolom menunjukkan bahwa alternatif penggunaan bahan perekat epoxy pada interface dinding dan kolom tidak dapat menggantikan angkur dinding dengan baja tulangan.

Many areas in Indonesia are located directly above active earthquake faults, making it relatively vulnerable to earthquakes. Earthquake-resistant house structures must be taken into account when planning a building. One of the earthquake-resistant structural systems in buildings is the bearing wall system. The advantage of this system is that the walls contribute to the strength of the structure in the direction of the plane (in plane), which is quite large. In this study, cyclic tests were conducted on precast structural portals with mechanical grouting connections that were given an autoclave aerated concrete (AAC) wall infill with the connection between the autoclave aerated concrete (AAC) and the structural components given an epoxy coating as a substitute for reinforcement cuttings and verified with models carried out with Abaqus FEA software. The cyclic test results showed maximum values of a push lateral load of 57.28 kN and a pull lateral load of 47.56 kN. These cyclic test results were verified by numerical modeling. These cyclic test results were verified by numerical modeling, the Abaqus model result for the lateral push was 56.68 kN (the ratio was 0.99) while that due to lateral pull was 46.73 kN (the ratio was 0.98). Both the test results and Abaqus modeling showed close lateral capacities. The portal shear capacity of the structure (Vcapacity) is 19.03 kN taken from the maximum tensile condition of 47.56 divided by the wall system strength factor (Ω0) of 2.5. The results of the analysis of the calculation of the base shear force (demand capacity) of the precast 1-story house structure can be applied to areas with SDS ≤ 0.710g (seismic design category “D”), but from the crack pattern and the detachment of the wall connection to the column indicate that the alternative use of epoxy adhesive material at the interface of the wall and column cannot replace the wall anchor with reinforcing steel.
