摘要：

To evaluate the hysteretic behavior of the low-yield-strength steel shear panel damper (LYSPD) accurately is very important for the dynamic analysis of the structure. Various analytical models for hysteretic behavior of the LYSPD are based on the static experiment results nowadays while it may be affected by dynamic loading speed, loading history and increased temperature. This paper presents a series of static and dynamic experimental investigations for examining the hysteretic behavior of the LYSPD. Obvious difference is observed between static and dynamic hysteretic curves. The test results suggest that the precise description of the nonlinear behavior of the LYSPD under static loading makes no sense. The nonlinear behavior of the LYSPD is replaced by linear strain hardening caused by dynamic loading speed and the perfect elastic-plastic model is more suitable for describing the hysteretic behavior of the LYSPD under dynamic random wave.
