| 摘 要： | 通过铅挤压消能器的低周反复加载试验,以及安装有铅挤压消能器的钢筋混凝土消能支撑框架模型结构的伪静力试验,主要研究了铅挤压消能器单独受反复荷载时的消能性能以及其在模型结构中所起的消能作用,模型结构的破坏机理和整体消能能力。研究结果表明,铅挤压消能器具有很好的消能能力,在模型结构总耗能中占据了很大的比例,模型结构具有较好的耗散地震能量的能力。

| Abstract: | Through the low-cycle test of the lead-extrusion dampers and the pseudo-static test of the reinforced concrete frame with lead-extrusion damper braces,energy-dissipation performance of the unattached lead-extrusion dampers and failure mechanism of the model structure are discussed.Sequentially,the paper is focused on the energy-dissipation effect of the lead-extrusion dampers in the model structure and the energy-dissipation capability of the model structure.The studied results are shown that the dampers have considerable effects on energy dissipation,and the energy dissipated by the dampers occupys a great part of the total energy dissipation in the model structure.In addition,the calculated results also verify the strong energy-dissipation capability of the model structure. |
