Kajian Numerik Struktur Rangka Terbreis Eksentrik dengan Link yang Dapat Diganti

Abstract

The Eccentric Braced Frame (EBF) is an earthquake resistant building system that has advantages in terms of strength and stiffness and has good ductility and energy dissipation capability in inelastic condition. Links are the most important elements that serve to dissipate the energy of the earthquake through the inelastic behavior of the structure. The performance of shear links is strength, stiffness, ductility and energy dissipation depending on the cross-sectional profile used on the link. This study aims to determine the relation behavior of RTE structures with links using bolt connections made of a variety of steel grades as well as applying Side Extended Plate (SEP) and those without SEP. The analysis was done using MSC PATRAN / NASTRAN software. As a total of eight link model variations were assessed to determine the most optimum performance of the structure when monotonic and cyclic static loading was carried out with displacement control. The results indicate that variations in the quality of the linked steel on the wing plate and body plate can significantly increase the strength, stiffness, and ductility of the structure compared with the use of SEP.
