| 摘 要： | 基于以往的试验研究进行室内振动台试验,模拟分析了钢筋混凝土墩及预应力墩的抗震性能.与普通钢筋混凝土桥墩相比,预应力钢筋利用预应力的高强弹性提高了墩柱的延性性能,降低了残余位移.由于预应力的存在,使得墩柱刚度较普通混凝土墩大,墩顶位移减小,墩底应力降低,能承受更大的地震加速度波.

| Abstract: | Indoor shaking table test was done based on previous experimental studies. The simulations of the seismic performance of prestressed piers and reinforced concrete piers are analyzed. Compared with ordinary reinforced concrete piers, prestressed concrete improves the ductility of piers, by using the high-strength elasticity of prestressing, and reduces the residual displacement. Since the presence of prestress. The stiffness of the pier is greater than ordinary concrete pier, the top displacement of pier is decreased, the bottom stress is reduced, and can withstand greater seismic acceleration waves. |
