Abstract

This paper highlights recent study on the seismic behavior of a newly developed self-centering structural frame system with reusable hysteretic damping braces (RHDB). RHDB is a passive energy dissipation device with its core energy dissipating component being superelastic shape memory alloy (SMA) wire stands. Compared to buckling-restrained braces (BRB), RHDB has a few favorable mechanical characteristics: damage free under frequent and design basis earthquakes; reduced residual drift due to its self-centering behavior; and reusability. A brief discussion on the mechanical properties of RHDB is provided. For a comparative study of BRB and RHDB, nonlinear time history analysis which involves three-story concentrically braced frames subjected to two suites of twenty earthquake ground motions was performed and the analysis results are presented in this paper. It is shown that RHDB is effective for passive response control of framed building structures and capable of reducing residual drifts of building frames.
