Abstract

Diantara beberapa sistem struktur Baja yang dikembangkan untuk struktur bangunan di wilayah yang rawan gempa, struktur EBF (Eccentrically Braced Frame) adalah yang paling populer. Sistem EBF merupakan kombinasi dari kedua system yang lain dimana menggabungkan kelebihan dari MRF (Moment Resisting Frame) dan CBF (Concentrically Braced Frame) serta mengurangi kelemahannya. Karakteristik EBF antara lain : 1) memiliki kekakuan elastis yang tinggi; 2) memiliki respons inelastik yang stabil di pembebanan siklik lateral; 3) Memiliki kemampuan ductilitas dan disipasi energi yang tinggi. Apabila ada beban gempa maka balok link akan in-elastic, sehingga dipilih vertical shear link (VSL), pertimbangannya link ini mudah diganti apabila ada kerusakan saat gempa besar tanpa mengubah bagian dari balok. Dari analisa menggunakan metode elemen hingga dengan program Abaqus, dimana menggunakan parameter pengujian eksperimental dari jurnal Bouwkamp dkk. (2016), didapatkan hasil validasi elemen link mengalami pelelehan dan mencapai kondisi plastis terlebih dahulu sedangkan elemen lain seperti balok, kolom dan bracing masih dalam kondisi elastis sehingga memenuhi persyaratan untuk EBF (Eccentrically Braced Frame). Dengan membandingkan kurva histeristis dan kapasitas disipasi energi dari hasil eksperimental jurnal Bouwkamp dkk. (2016) dengan permodelan Abaqus didapat selisih masih di bawah 5% sehingga dapat diambil kesimpulan validasi dapat digunakan sebagai dasar permodelan untuk EBF.

Among several steel structure systems developed for building structures in earthquakeprone areas, the EBF (Eccentrically Braced Frame) structure is the most popular. EBF system combine each advantage from both structure systems and eliminates the weakness. The EBF characteristics are: 1) has a high elastic stiffness; 2) has a stable inelastic response under lateral cyclic loading; 3) has a high ductility and energy dissipation ability. In the EBF system, inelastic behavior is required to occur in the link beam during earthquake loading, one of the links being studied at this time is VSL (Vertical Shear Link) which has the advantage of being easy to replace in case of damage and maintaining the accuracy of work on the beam above it. The analysis using the finite element method with the Abaqus program, which uses experimental test parameters from the journal of Bouwkamp et al. (2016), validation results show that the link elements yielded and reach a plastic condition first, while other elements such as beams, columns and bracing are still in an elastic condition so that they meet the requirements for EBF (Eccentrically Braced Frame). By comparing the hysteristic curve and dissipation of energy from experimental results of the journal Bouwkamp dkk. (2016) with the Abaqus modeling, a difference which is still below 5% so that it can be concluded that the results of the validation results can be used as a basis for modeling for EBF.
