本文介绍了新型摩擦阻尼系统的测试结果，该系统的提出是为了提高钢抗力矩框架（MRF）和支撑抗力矩框架（BMRF）在严重地震期间的响应。该系统由一个机构组成，该机构包含在框架横撑交叉处引入的制动衬片。在地震模拟器台上对三层摩擦阻尼支撑框架（FDBF）模型进行了地震试验。将实验结果与非弹性时程动态分析的结果进行比较。结果清楚地表明 FDBF 与传统建筑系统相比具有优越的性能。
This paper presents the results obtained from tests of a new friction damping system, which has been proposed in order to improve the response of steel Moment Resisting Frames (MRF) and Braced Moment Resisting Frames (BMRF) during severe earthquakes. The system consists of a mechanism containing brake lining pads introduced at the intersection of frame cross-braces. Seismic tests of a three storey Friction Damped Braced Frame (FDBF) model were performed on an earthquake simulator table. The experimental results are compared with the findings of an inelastic time-history dynamic analysis. The results clearly indicate the superior performance of the FDBF compared to conventional building systems.
