Abstract

In this paper, aluminum panels were used to improve the seismic behavior of the braced steel frames. One of the methods used to improve the seismic behavior of structures is the use of vertical links as energy dissipation systems. Aluminum has a low yielding stress and it yields faster than steel which results in a significant ductility. The investigation method was simulation by ABAQUS software. The steel frames with 1, 4, 8 and 12 stories were modeled by four different bracing systems and two types of rectangular and square aluminum panels. The results of using aluminum panels were compared with Easy Going Steel (EGS) through the structure capacity curves. The results indicate that using the aluminum panel as vertical link in braced steel frames made significant energy dissipation.
