摘　　要：通过对一3层3跨相似比为1/8的带铅挤压消能器消能支撑框架模型结构的伪静力试验,研究了铅挤压消能支撑框架结构的破坏形态、屈服顺序和消能机理,并从延性和被动消能等方面综合评价了其抗震性能.结果表明,铅挤压消能支撑框架具有良好的抗震效果.An experiment is carried out on a three-story and three-span 1/8 scale reinforced concrete frame model with energy dissipation braces formed by lead extrusion dampers under pseudo-static loading. Failure mechanism, plastic hinges forming and energy dissipation capacity for the energy dissipation braced frame are discussed. The aseismic behavior is evaluated by the ductility and energy dissipation. The test and analysis show that this type of energy dissipation braced frame has fine aseismic behavior.
