“…Karena itu peredam (damper) mengurangi penambahan energi regangan dan respon dari sistem, terutama kondisi dimana mendekati resonansi dimana peredam mengontrol respon. Besarnya nilai redaman tergantung dari beberapa faktor seperti amplitudo getaran, material konstruksi, periode getaran, mode shapes, dan konfigurasi struktur [9].…”

Beam and column connections are one of the elements in steel frame structure that are important in the design of earthquake resistant building construction. The semi-rigid connection regulated in the regulation allows connection of the structure to experience a slight rotation. Selection of the right connection is very necessary to ensure the occurrence of plastic joints in the beam area. This study discusses the behavior of T-Stub joint type steel connections equipped with friction dampers when given cyclic loads using software based on ABAQUS 6.14. This study will do modeling which then results will be compared from moment -rotation, rotational stiffness value and failure mode using software based on ABAQUS 6.14. The modeling used I-Shaped welded plate for beam dimensions 135 × 270 × 6.6 × 10.2 mm and column dimensions 260×200× 9×15 mm, and column stiffness thickness 10.2 mm. The modelling was made in four types. Two type modelling for verification of previous research and the other two modelling are another modified connection. results of the modeling above when compared with the results of the experiments used do not have a significant difference ductility, Modelling with Hauch and Ribs more ductile better than modelling no Hauch and Ribs in connection. The most effective connection modelling was connection with equipped stifener like Hauch and Ribs. It is expected that all beam-column joint modeling with equipped friction damper can be used in earthquake resistant structures Kata kunci: friction damper, pembebanan siklik, T-stub, finite element method, sambungan baja Abstrak Sambungan balok dan kolom merupakan salah satu elemen dalam struktur rangka baja yang penting dalam desain konstruksi bangunan tahan gempa. Sambungan semi rigid yang diatur dalam peraturan memperbolehkan sambungan struktur untuk mengalami sedikit rotasi. Pemodelan yang digunakan welded plate I-Shaped untuk dimensi balok 135 × 270 × 6.6 × 10.2 mm dan dimensi kolom 260 × 200 × 9 × 15 mm, ketebalan pengaku kolom 10.2 mm. Variasi spesimen dibuat sebanyak empat jenis. Dua untuk verifikasi penelitian sebelumnya dan dua lainnya merupakan sambungan modifikasi. Hasil dari studi spesimen dan pemodelan memiliki selisih yang tidak terlalu signifikan. Ditinjau dari nilai daktilitasnya sambungan dengan tambahan hauch dan ribs lebih daktail bila dibandingan dengan dua model lainnya. Dari semua variasi pemodelan sambungan, sambungan yang dilangkapi dengan Hauch dan Ribs memiliki performa lebih baik. Dari semua pemodelan sambungan balok -kolom yang dilengkapi dengan friction damper diharapkan dapat digunakan pada struktur yang tahan gempa.

“…However, the columns cannot be ensured completely in the axial compression stage in building structures. For example, many high-rise buildings, frame columns, trusses of the roof, and support columns of bridges are always under eccentric compression, which is true in general for beam-columns (Danesh and Mohammadrezapour 2018;Sui et al 2018;Hu et al 2020;Tan et al 2020). The bending deformation under eccentric loads can affect its ultimate bearing capacity, and the nonlinear deformation reduces it further.…”

To improve the utilization rate of bamboo, glued laminated bamboo hollow column (GLBHC) was examined under eccentric compression to study the effects of different slenderness ratios, eccentric distances, and wall thicknesses on its ultimate bearing capacity. The nonlinear deformation of the material and the P-delta effect of the column occur under eccentric compression, which can affect its ultimate bearing capacity, so it is very important to analyze the elastic-plastic buckling of the column. Moreover, the discontinuity of the hollow column section aggravates the nonlinear deformation. To accurately estimate the ultimate bearing capacity of GLBHC, considering the difference in tensile and compression elastic modulus, two eccentric compression models were established. A formula for ultimate bearing capacity of the GLBHC under eccentric compression was proposed, and the calculated results were in good agreement with the test results.
