Abstract

Hollow Flange Steel Plate Girder (HFSPG) merupakan profil-I baja yang berbentuk persegi berlubang pada bagian sayap dan pelat pada bagian badan. Proses pembentukan profil ini memerlukan proses cold-formed. Sambungan antara bagian badan dengan sayap menggunakan sambungan las yang berfungsi mengurangi terjadinya kegagalan sambungan antara bagian badan dengan sayap. Profil tersebut memiliki kekakuan torsi yang baik, sehingga dapat meningkatkan kapasitas lentur dan material ini dapat diaplikasikan secara efektif dalam bentang panjang (Perera et al., 2018). Profil baja sayap berlubang diharapkan memiliki nilai kekakuan dan kekuatan yang lebih baik dibandingkan dengan baja canai dingin, karena letak geografis Negara Indonesia yang rawan bencana alam, sehingga profil tersebut tidak mudah mengalami local buckling. Sebagai akibatnya dalam penelitian ini akan dilakukan variasi penebalan profil baja sayap berlubang. Metodologi penelitian terdiri dari dua tahapan, tahap awal yaitu analisis validasi dari spesimen model eksperimental Perera et al. (2018), kemudian hasil analisis validasi tersebut dilakukan perbandingan antara momen kurvatur model numerik dan momen kurvatur model eksperimental. Selain itu, hasil tersebut akan divalidasi menggunakan perhitungan analitis dari SNI 1729:2020. Tahapan selanjutnya adalah melakukan pemodelan variasi terhadap dimensi penampang, ketebalan profil, dan mutu baja. Hasil penelitian menunjukkan bahwa baik penambahan dan pengurangan dimensi berpengaruh pada momen kurvatur dan defleksi sesuai dengan momen inersia, modulus elastis, dan modulus plastis. Kemudian, penambahan mutu menunjukkan peningkatan momen kurvatur dari model validasi, dan penambahan ketebalan juga menunjukkan peningkatan momen kurvatur.

Hollow Flange Steel Plate Girder (HFSPG) is I-profile steel in the form of a square with holes on the wings and plates on the body. The process of forming this profile requires a cold-formed process. The connection between the body and the flange uses a welded joint which serves to reduce the occurrence of joint failure between the body and the flange. The profile has good torsional rigidity, so it can increase the flexural capacity and this material can be applied effectively in long spans (Perera et al., 2018). Perforated flange steel profiles are expected to be better values in rigidity and strength than cold-formed steel, due to the geographical locations of Indonesia which are prone to natural disasters, so the profile is not prone to local buckling. As a result, variations in the thickness of the perforated flange steel profile will be carried out in this research. The research methodology consists of two stages, the initial stage is the validation analysis of the experimental model specimens by Perera et al. (2018), then the results of the validation analysis carried out a comparison between the curvature moment of the numerical model and the curvature moment of the experimental model. In addition, these results will be validated using analytical calculations from SNI 1729:2020. The next stage is to model variations on crosssectional dimensions, profile thickness, and steel quality. The results show that both the addition and reduction of dimensions have an effect on the curvature and deflection moments according to the moment of inertia, elastic modulus, and plastic modulus. Then, the addition of quality shows an increase in the curvature of the validation model, and the addition of thickness also indicates an increase in the curvature of the model.
