摘要

摘要: 基于已经开展的新型耗能杆增强预应力装配式混凝土框架节点试验建立了OpenSees分析模型。首先,通过数值分析结果与试验结果对比,表明有限元模型能够准确地反映节点承载能力和自复位特性。其次,随着附加耗能杆所用材料的屈服点的增加,新型耗能杆增强预应力装配式混凝土框架节点的承载力与耗能能力增加,具有较低屈服点的耗能杆能够较早地为预应力装配式混凝土框架节点提供耗能能力;最后,与采用附加软钢耗能杆的预应力装配式混凝土框架节点相比,当采用铝合金耗能杆时,虽然节点的承载力基本保持相同,但是节点的刚度和屈服点明显降低。

Abstract: The numerical model in OpenSees was established based on the previous research on the new prestressed prefabricated concrete frame connection strengthened by energy dissipaters. Firstly, the numerical results were compared with experimental results, which demonstrated that the proposed numerical model could simulate the bearing capacity and self-centering characteristics of the connection well. Secondly, the bearing capacity and energy dissipation capacity of the new prestressed prefabricated concrete frame connection were found to increase with the increase of the yield stress of energy dissipater, but the prestressed prefabricated concrete frame connection with energy dissipaters with lower yield stress could dissipate the energy earlier. Finally, compared with the prestressed prefabricated concrete frame connection installed with mild steel dampers, the prestressed prefabricated concrete frame connection installed with aluminum alloy dampers sustained similar bearing capacity but had lower connection's stiffness and yielding force.
