拼装式桥墩接头的承载能力与滞回特性的试验研究

EXPERIMENTAL STUDY ON LOADING CAPACITY AND HYSTERETIC PROPERTIES OF ASSEMBLED BRIDGE PIER JOINTS

摘要: 通过模型试验研究了拼装式双柱桥墩帽梁一柱的插入式接头及新设计的预应力接头的抗震承载能力、滞回特性。在试验的基础上给出了接头极限承载力的简化计算公式,计算结果与模型试验结果吻合较好。并按现行规范对接头进行了抗震验算。

Abstract: The aseismic behaviour and the hysteretic properties of the assembled double-column bridge pier were studied by a model test. Based on the test and analysis a simplified formula for the joints' aseismic calculation was developed. The calculated results are in good agreement to those of the model test. The aseismic checking was performed on the basis of the current aseismic code.
