Abstract

Selama ini di dalam desain struktur Eccentrically Braced Frames (EBF), link selalu didesain secara menyatu dengan balok lantai sehingga menyebabkan terjadinya overstrength pada bagian tersebut. Selain itu, desain tersebut juga menjadikan perbaikan pasca gempa menjadi kurang efisien baik dalam segi waktu serta biaya. Selama satu dekade ini, mulai banyak penelitian yang memodelkan replaceable link dengan berbagai pengembangan untuk mendapatkan elemen yang daktail ketika menghadapi gempa, begitu juga dengan penelitian ini. Penelitian ini bertujuan untuk mengetahui perilaku link dengan berbagai macam material terhadap daktilitas, energi disipasi, deformasi dan rotasi, serta pola kegagalan pasca terjadi gempa. Pada penelitian ini dilakukan pengujian terhadap empat spesimen web bolted replaceable link dengan variasi material baja konvensional dan juga baja low yield pont (LYS). Analisa dilakukan dengan metode numerik yaitu dengan mengaplikasikan beban siklik bolak balik pada elemen link. Beban tersebut kemudian dikontrol trerhadap perpindahan di salah satu ujung link. Kemudian hasil pengujian dianalisa berdasarkan daktilitas, energi disipasi, deformasi, serta pola kegagalan. Hasil pemodelan menunjukkan link dengan tipe sambungan web bolted menghasilkan kurva dengan pinching effect yang disebabkan oleh sambungan baut. Selain itu, link LYS100 menunjukkan nilai rotasi yang besar dikarenakan material tersebut memiliki regangan ultimate yang lebih besar dibanding dengan baja konvensional. Dari pemodelan numerik didapatkan bahwa replaceable link dengan material LYS hasilnya sebanding dengan link dengan baja konvensional serta link tersebut mampu memenuhi persyaratan terkait daktilitas, kemampuan mendisipasi energi, serta besar rotasi yang dihasilkan.

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. Dalam penelitian ini, akan dilakukan studi numerik (finite element method) mengenai profil Hollow Steel Plate Girder. Berdasarkan studi numerik akan ditinjau mengenai kapasitas momen profil, kurva histerisis, daktilitas, pola kegagalan profil, dan sambungan antar profil baja sayap berlubang. Parameter pengujian menggunakan hasil penelitian dari Perera et al. (2018) yang akan dikembangkan sesuai dengan pemodelan yang dibutuhkan.

Abstract

This article presents the results of a research project that aimed to evaluate how the number of fiber-reinforced polymer (FRP) layers and the compressive strength of concrete affect the stress-strain behaviors of concrete columns produced from artificial lightweight aggregate with square cross-sectional shapes. Eighteen test specimens were manufactured and wrapped with glass fiber-reinforced polymer (GFRP) material. The specimens were later subjected to concentric compression for experimental evaluation. The experimental results suggest that GFRP efficiently confines square lightweight aggregate concrete columns. Furthermore, the test results indicate that adding FRP layers augments the ultimate stress and strain. Finally, the results suggest that an increase in the compressive strength of concrete leads to a corresponding increase in the ultimate stress. On the other hand, it has been observed that the ultimate strain decreases as compressive strength increases. The research findings reveal the behaviour of FRP-confined square lightweight aggregate concrete columns, which may also be utilized to formulate a new design-oriented model for these columns.

Abstract

Eccentrically Braced Frames (EBFs) are earthquake-resistant steel structures with excellent shear capacity and ductility. During earthquakes, the EBF link yields first, protecting other structural elements. Traditionally, the link is integrated with the main beam and separated by bracing. However, if the link is damaged, replacing the entire beam becomes necessary. To address this, a vertical link design allows for link replacement without altering the beam section. This study evaluates two vertical link options: a Wide Flange (WF) link section and a Hysteretic Steel Damper (HSD) type Metallic Yielding Damper. Results suggest the WF link is preferable due to superior shear capacity and energy dissipation compared to the HSD link. The findings recommend the WF link for vertical link EBFs to optimize earthquake performance.

Abstract

This study provides a detailed investigation of the material behavior of concrete-filled double-skin tubes (CFDST). The research primarily focuses on the development and examination of cross-sectional variations, stress-strain relationships in the materials, and their corresponding characteristics. By conducting a comprehensive study and evaluation, this research endeavors to provide a more profound comprehension of the impact of this particular behavior on the overall responsiveness and capacity of materials. The influence of various parameters on a variety of cross-sectional configurations, comprising circular outer and circular inner tubes (C-C), circular outer – square inner tubes (C-S), square outer – circular inner tubes (S-C), square outer – square inner tubes (S-S) have been recently examined in earlier research. Furthermore, this study discusses additional evaluations consisting of sandwiched concrete and the inner and outer steel components. Despite the substantial study conducted by CFDST, there is presently a lack of established guidelines or regulations pertaining to the design of composite structures. Consequently, it is imperative to acquire a comprehensive comprehension of the behavior exhibited by these materials. This understanding serves as essential for the development of design rules specific to CFDST composite structures. By performing consequently, the outcomes of this study can be effectively employed in the design, analysis, and optimization of the distinctive attributes associated with composite materials.
