Abstract

In this study, the performance evaluation of steel dampers was conducted based on existing research results. The test variables are cross-sectional shape and lateral deformation prevention details. As a result of performance tests according to cross-sectional shape, the circular cross-section was evaluated to be superior than the rectangular cross-section in terms of envelope, stiffness reduction, and energy dissipation capacity. In addition, it was evaluated that the rectangular cross-section where lateral deformation occurs can be restrained by lateral deformation prevention details, thereby improving strength and deformation capacity.
