| Popis: | Conducting research in anticipating earthquake damage at building has been developed continuosly. One of it is Eccentrically Braced Frame (EBF) for steel frame. EBF uses link element to absorb earthquake energy. Failure at long type link dominantly is caused by moment which make early failure because of fracture and buckling at the end of link such as in its flange. To tackle the early failure, stiffener at the end of the link has been added. The advantages of it are making easy of workmanship and minimizing the welding effort which can reduce residual stress because of welding process. This study does numerical study by using MSC Nastran/Patran program to measure the performance of long type link for several analysis types. Several parameters have been analyzed such as the length of the link, the edge addition of flange plate with its modeling configuration, the width of the plate, and the combination with vertical body stiffener. This study found that the addition of stiffener at the end of the link has increased the performance of long type link. Finally, the findings of this study are compared with that of standard link model. The variables that are compared between both of long type link and standard link are ductility, strength, energy dissipation and stiffness. |
