摩擦耗能支撑钢筋混凝土框架结构的振动台试验研究

Study on Shaking Table Test of RC Frame Model with Friction Energy-dissipation Bracings

本文通过一榀普通钢筋混凝土框架、一榀钢支撑钢筋混凝土框架和一榀摩擦耗能支撑钢筋混凝土框架1／8比例模型的地震模拟振动台对比试验，研究三类不同型式框架结构在地震作用下的破坏形态和动力特性，揭示了摩擦耗能支撑钢筋混凝土框架结构良好的抗震性能，为此类新型结构的工程应用提供了试验依据。

Three 1/8 scale reinforced concrete frame models, including one with a steel bracing, onewith a friction energy-dissipation bracing and the third one without bracing, have been tested onshaking table for comparison. The failure modes and dynamic characteristics of these three kindsof frame structures under earthquake wave are studied. Tests show that the friction energy-dissipation braced frame has excellent behavior and can be proposed for practical use.
