Pemakaian material baja sebagai bahan bangunan dalam struktur gedung saat ini masih sedikit. Penggunaan struktur rangka baja memiliki keunggulan tersendiri dibandingkan dengan struktur lain. Struktur bangunan yang menggunakan struktur rangka baja biasanya merupakan bangunan bertingkat yang menahan beban yang relatif besar. Pada penelitian ini akan dibahas perhitungan portal pada balok dan kolom…
Earthquake retaining structures required to reduced the negative effect of earthquake. This Building with steel structure use steel Concentrically Braced Frame (CBF). This research used 5 models of steel buildings with the same size 18 m x 18 m and the height 40 m. This buildings serves as an office building and was built on soft soil condition. Steel building used 2 types of bracing CBF, Xbrac…
Dalam mengurangi gaya gempa yang terjadi pada suatu struktur umumnya digunakan peredam gempa. Salah satu peredam gempa yang biasanya digunakan adalah bracing. Dalam studi ini digunakan bracing jenis EBF (Eccentrically Braced Frames). Studi ini menggunakan lima model gedung baja 10 lantai dengan ukuran setiap model 18 m x 18 m dan tinggi tiap lantai 4 m. Gedung berfungsi sebagai gedung kantor di…
In this study, a comparison of steel frame structure consisting of drift, interstory drift, drift ratio, and response time history structure outputs in the form of displacement, velocity, and acceleration with split-K braced EBF and inverted-V braced CBF was carried out. The analyzed structure was assumed to be a 10-storey office building located on soft ground. The method used was a dynamic ti…
An example of an earthquake-resistant building uses an eccentrically braced frame (EBF) reinforcement system. the advantage of this system is that it can correct the shortcomings of two conventional frames, namely the moment-resisting frame and concentric retaining frame. In this study, a 10-storey was examined using ETABS 18, with time history analysis method. There are two modellings, the fir…
Earthquakes are one of the causes that can damage building structures and could make the died. Earthquake-resistant buildings are needed to avoid construction losses and the safety of their occupants. Eccentrically braced frame (EBF) is a system that is applied only to frame structures for earthquake-resistant buildings that have good ductility and elastic stiffness. This research aim to analyz…
The study analyzed comparison of earthquake-resistant steel structures compared between two models is diagonal concentrically braced frames with diagonally eccentrically braced frames. Fixed variables are a 10-story office building, structure load, and steel profile dimensions. Variable changes consist of the type of braces used. Data time history and location of the building using data from th…
