【摘要】：针对提高装配式桥墩抗震性能的不同方法,从结构刚度、抗剪能力、自复位能力、延性耗能和施工便易性等方面对比分析了其优缺点、适用性及研究思路等。首先,基于装配式桥墩抗震设计的难点和抗震性能的主要缺陷,提出该问题的研究背景;其次,分别从改进结构形式与材料、节段连接方式以及设置耗能装置等角度,归纳对比了国内外提升装配式桥墩抗震性能的主要措施;然后,剖析了这些措施的相关研究思路与研究方法。在此基础上,提出有待进一步研究的主要问题,即完善适合于装配式桥墩的理论分析方法,开展装配式双柱墩的抗震性能研究,提高装配式桥墩建造的便利性与经济性,并从桥梁体系的角度来分析其抗震性能。
[Abstract]:Aiming at the different methods of improving the seismic performance of assembled piers, the advantages and disadvantages, applicability and research ideas are compared and analyzed from the aspects of structural stiffness, shear resistance, self-reset ability, ductile energy dissipation and ease of construction. Firstly, based on the difficulties in seismic design of assembled piers and the main defects of seismic performance, the research background of this problem is put forward. Secondly, from the angles of improving structure form and material, connecting mode of segment and setting up energy dissipation device, etc. This paper summarizes and compares the main measures of seismic performance of hoisting assembled piers at home and abroad, and then analyzes the relevant research ideas and methods of these measures. On this basis, the main problems to be further studied are put forward, that is, to perfect the theoretical analysis method suitable for the assembled pier, to carry out the research on the seismic behavior of the assembled double-column pier, and to improve the convenience and economy of the construction of the assembled pier. The seismic performance of the bridge system is analyzed from the point of view of the bridge system.
