摘要: 研发了一种新型震损可修复的预制拼装混合墩结构。对该混合墩以及钢筋混凝土桥墩(RC墩)对比件进行水平低周往复荷载试验。试验结果表明:混合墩的损伤主要集中在可更换薄壁钢管,墩身保持弹性;在相同位移角下,混合墩的残余位移显著低于RC墩。当位移角达到2.0%的峰值荷载时,混合墩的残余位移角仅为0.2%,充分验证了其良好的自复位能力;混合墩的极限位移角θu约为5.6%,其变形能力远大于RC墩(θu=3.1%);由于混合墩具有更好的变形能力,其最终累积耗能大于RC墩。混合墩的抗弯承载力由竖向轴力和可更换薄壁钢管提供,基于此提出了混合墩的抗弯承载力计算公式。

Abstract: A new type of earthquake resilient precast hybrid pier was developed. The horizontal low cycle reciprocating load tests were carried out on the proposed hybrid pier and the RC pier counterpart. The test results show that the damage of the hybrid pier is mainly concentrated on the replaceable thin-walled steel tube, and the pier body remains elastic. At the same displacement angle, the residual displacement of the hybrid pier is significantly lower than that of the RC pier. When the displacement angle reaches the peak load of 2.0%, the residual displacement angle of the hybrid pier is only 0.2%, fully verifying its good self-centering ability. The ultimate displacement angle (θu) of the hybrid pier is about 5.6%, and its deformation capacity is much greater than that of the RC pier (θu =3.1%). Due to the better deformation capacity of the hybrid pier, its final cumulative energy consumption is greater than that of the RC pier. The flexural capacity of the hybrid pier is provided by the vertical axial force and the replaceable thin-walled steel tube. Based on this, the calculation formula of the flexural capacity of the hybrid pier is proposed.
