Abstract


Eccentrically Brace Frame system develops its ductility using link inelasticity. Therefore, the strength of the structure in resisting the lateral force is highly dependent on the link and some types of link that are commonly used. Furthermore, it needs to compare the behavior of two section frames that most commonly used as a link in EBF system building; they are WF section and tubular section. In addition to the cross-sectional factors, deformation of the link is also highly dependent on the length of the link, hence the test will also be done on three different type of link lengths, they are short links, intermediate links, and long links, that are according to the classification of link lengths defined in AISC Seismic Provision. Before starting the analysis, a literature study has been reviewed to learn more about the behavior of a link under cyclic load. The numerical analysis has been done to find the strength of the link and modeling with the Finite Element Analysis (FEA) using ABAQUS. After all analysis and the calculation are completed, the results will appear in three-dimensional modeling form, Displacement versus Force diagrams and the stress-strain curves to show the ductility of all specimens. The result of the study showed that in short links, both WF link and tubular link achieve nominal shear force is equal to Vp plastic shear force with values 390 kN for tubular section and 437 kN for WF section, and the value of shear force to the classification of the short link is very dependent on the body cross-sectional area. Tubular link’s body with an area of 89% of the WF link total weight generates shear forces 89% of the shear force from WF link because the formulation of the plastic shear force Vp is highly dependent on factors of body cross-sectional area (Aw). According to the research result, it shows that for both WF and tubular link cannot reach nominal shear force when the length of the link over the requirement of the shear link.
