Deck type steel arch bridge anti-seismic structure system
The invention discloses a deck type steel arch bridge anti-seismic structure system, which comprises a main arch ring and a main beam, wherein the two ends of the main arch ring are fixed to a foundation through arch bases; the main beam at most comprises a coupling beam body in the vertical projection range of the main arch ring; the bottom of the main beam is rigidly connected with the arch crown of the main arch ring through arch crown short stand columns. Through rigid consolidation of the main beam on the arch and the main arch ring, when an earthquake occurs, huge earthquake force of the main beam is directly transmitted to the main arch ring and then transmitted to the foundation through the arch seat, the earthquake force transmission path is direct and efficient, the earthquake force borne by the column on the arch is reduced, the anti-seismic performance of the whole structure is improved, arrangement of a seismic mitigation and isolation system in conventional design is avoided, and the advantages of good economical efficiency, simple structure, convenience in construction, good structural durability and the like are achieved.
本发明公开了一种上承式钢拱桥抗震结构体系，包括主拱圈和主梁，主拱圈两端通过拱座固定在基础上；主梁在主拱圈竖向投影范围内至多包括一联梁体；主梁底部与主拱圈的拱顶通过拱顶短立柱刚性连接。本发明通过拱上主梁与主拱圈刚性固结，地震发生时，主梁巨大的地震力直接传递至主拱圈，进而通过拱座传递至基础，地震力传力路径直接高效，减小了拱上立柱承担地震力，提高了整个结构的抗震性能，避免了常规设计中减隔震系统的设置，具有经济性好、构造简单、施工方便、结构耐久性好等优点。
