该试验使用的新型黏弹性.软钢剪切型组合耗能器是由高阻尼橡胶材料、低屈服点软钢板、盖板、连接钢板及加劲肋组成。该试验在同济大学静力试验室进行,采用SCHENCK作动器对该耗能器进行了渐增位移往复加载试验和固定位移往复加载试验,以测定该耗能器的基本性能和疲劳性能。试验的测量内容为组合耗能器加载过程中的阻尼力及位移,阻尼力和位移由作动器反馈给试验系统得到。
The new viscoelastic, mild steel shearing combination energy dissipater used in this test is composed of a high damping rubber material, a low yield point mild steel plate, a cover plate, a connecting steel plate and a stiffener. The experiment was carried out in the static test room of Tongji University. The reciprocating loading test and the fixed displacement reciprocating loading test were carried out on the energy dissipater with SCHENCK actuator to determine the basic performance and fatigue performance of the energy dissipater. The measurement of the test is the damping force and the displacement during the loading of the combined energy dissipater. The damping force and the displacement are obtained by the actuator feedback to the testing system.
