ABSTRACT

This study attempts to investigate the effect of the BRB distribution on the seismic performance of retrofitted multi-story RC tall bridge bents. Different BRB distributions were compared, from which the most efficient one was identified. The results showed that uniform distribution was not necessarily an efficient retrofit option. By controlling the same damage, using triangular cumulative distribution to design multi-story BRBs led to the least consumption of brace material. Alternatively speaking, with the same consumption of BRBs, the triangular cumulative distribution of braces was the most effective in controlling the damage of the tall bridge bents.

多层支撑分布对加装屈曲约束支撑的 RC 高弯桥抗震性能的影响

摘要

本研究试图研究 BRB 分布对改造后的多层 RC 高桥弯架抗震性能的影响。比较了不同的 BRB 分布，从中确定了最有效的分布。结果表明，均匀分布不一定是有效的改造方案。通过控制相同的损坏，使用三角累积分布设计多层 BRB 导致支撑材料的消耗最少。换句话说，在BRB消耗量相同的情况下，支撑的三角形累积分布对控制高大桥弯的破坏最有效。
