摘　　要：型钢骨架-混凝土(后称PSSC)桥墩,不同于传统钢筋混凝土(后称RC)桥墩,墩身内部是混凝土与型钢骨架通过栓钉连接成为整体受力。以浏阳河桥PSSC桥墩为例,进行了静动力有限元对比分析。计算结果显示,PSSC桥墩同样满足设计要求;在强度和刚度方面优于RC桥墩。Profile steel skeleton concrete(hereinafter referred to as PSSC) pier is different from traditional reinforced concrete(hereinafter referred to as RC) pier. Inside the pier shaft, concrete and profile steel skeleton are connected by studs to form an overall to sustain loads. Taking the PSSC pier of Liuyang River Bridge as an example, the static and dynamic finite element comparative analysis is carried out. The calculation results show that PSSC piers also meet the design requirements;It is superior to RC pier in strength and stiffness.
