Abstract

Penerapan metode modular diaplikasikan pada pembangunan rumah hunian di Ibu Kota Nusantara dan hal yang perlu diperhatikan yaitu pada sambungan karena berpengaruh terhadap kecepatan proses pelaksanaan konstruksi, kekakuan antar modul dan stabilitas keseluruhan bangunan. Jenis sambungan yang dipakai berdasarkan jurnal penelitian oleh Yuan et al, 2023 yang memiliki keunggulan diantaranya efisiensi konstruksi karena tidak ada pengelasan di lapangan, komponen sambungan relatif sederhana tanpa perangkat self-locking, bagian cover plate dapat memperbesar kapasitas geser dan tarik sambungan serta mengurangi konsentrasi tegangan pada area sambungan. Tujuan dari penelitian ini yaitu untuk menganalisis pemodelan sambungan jenis bolted-cover plate dari segi gaya, perpindahan yang terjadi dan disipasi energi yang mampu diserap struktur. Analisis pertama meliputi tahap pemodelan struktur, kontrol dinamis struktur, kontrol elemen struktur, dan analisis pushover, kemudian analisis berikutnya dengan memodelkan sambungan pada abaqus. Hasil dari kontrol dinamis yaitu diperoleh nilai simpangan antar lantai pada lantai 4, 3, 2, dan 1 arah X dan Y, berturut-turut adalah (2,487; 7,329) mm, (5,760; 10,896) mm, (11,835; 17,574) mm, (9,678; 12,339) mm. Perencanaan struktur dapat mengabaikan p-delta karena masih dalam batas yang diizinkan. Pada analisis pushover, didapatkan level kinerja struktur berada di level B to IO life safety. Validasi numerik terhadap balok diperoleh distribusi tegangan pada sambungan arah X dan Y memiliki kemiripan/tipikal yaitu pada keempat balok terjadi pemusatan tegangan di area sendi plastis. Untuk nilai force dan displacement arah X dan Y masing – masing sebesar 348,585 kN; 165,805 mm dan 310,872 kN; 163,71 mm dan energi disipasi masing – masing sebesar 90,481 kN.m dan 98,806 kN.m. Grafik momen – rotasi menyimpulkan bahwa kekakuan sambungan dikategorikan sebagai sambungan semi rigid.

The application of the modular method is applied to the construction of residential houses in the Capital City of the Archipelago with the advantage of accelerating construction by 50% from conventional methods and cutting costs by 20% from conventional methods. Things that need to be considered are the connections because they affect the speed of the construction process, the stiffness between modules, and the overall stability of the building. The type of connection used is based on a research journal by Yuan et al., 2023, which has advantages including construction efficiency because there is no welding in the field, the connection components are relatively simple without self-locking devices, and the cover plate section can increase the shear and tensile capacity of the connection and reduce stress concentration in the connection area. The purpose of this study is to analyze the modeling of bolted-cover plate-type connections in terms of force, displacement that occurs and energy dissipation that can be absobed by structure. The first analysis includes the structural modeling stage, dynamic control of the structure, structural element control, and pushover analysis, and then the next analysis is by modeling the connection in abaqus. The results of dynamic control are obtained from the deviation values between floors on floors 4, 3, 2, and 1 in the X and Y directions, respectively: (2.487; 7.329) mm, (5.760; 10.896) mm, (11.835; 17.574) mm, and (9.678; 12.339) mm. Structural planning can ignore p-delta because it is still within the permitted limits. In the pushover analysis, the structural performance level was obtained at level B to IO life safety. The dimensions of the column used SHS profile 200 x 200 x 16, an X-direction beam with C profile 300 x 100 x 10 x 16, and a Ydirection beam using C profile 200 x 75 x 8.5 x 11.5 and bolts with a quality of A325. Numerical validation of the beams obtained stress distribution at the X and Y direction joints that have similarities/typicality, namely, in the four beams there is stress concentration in the plastic joint area. The force and displacement values in the X and Y directions, respectively, are 348.585 kN and 165.805 mm and 310.872 kN and 163.71 mm, and the dissipation energy is 90.481 kN.m and 98.806 kN.m. The moment-rotation graph concludes that the stiffness of the connection is categorized as a semi-rigid connection.
