摘要:
基于可快速修复的理念,提出一种墩底隔震的城市高架桥梁结构体系。探讨了新型结构体系的设计原则、施工难点和独特的抗震构造措施。以某高架桥为实例,将新型体系和传统的墩顶隔震体系进行对比研究。结果表明:与墩顶隔震体系相比,新型体系的支座位移和桥墩最大弯矩基本相同,但是对桩基的抗震要求有很大程度的降低;新型体系的整体性更好。
Abstract:
Based on resilient design method, a base-isolated viaduct system was proposed. Design principles, construction difficulties and special aseismic measures were discussed. With an example of a viaduct, effects of the proposed system and traditional isolated viaduct system were compared. It turns out that bearing deformations and the maximum moment of piers of the proposed system are almost the same as the traditional isolated systems. However, demands of piles of the new system are very low compared with traditional isolated viaduct systems. Moreover, it has good integrity.
