13-meter span hinge-joint-free hollow slab structure and design method
The invention discloses a 13-meter-span hinge-joint-free hollow slab structure and a design method. The 13-meter-span hinge-joint-free hollow slab structure comprises boundary beams, a middle beam, a reinforced concrete bridge deck pavement layer, a double-layer reinforcing mesh, a top plate, a web plate, a bottom plate, flanges, a 4phi s15.2 prestressed steel beam I and a 3phi s15.2 prestressed steel beam II. And the side beams and the middle beams as well as the middle beams are connected into a whole through reinforced concrete bridge deck pavement layers. In the design, boundary beams, middle beams and a reinforced concrete bridge deck pavement layer are simulated by adopting space beam units, and are analyzed and calculated through a finite element program. According to the method, the overall structure stress of the hollow slab bridge can be improved, the bridge disease hidden danger can be effectively reduced in the new bridge design, the management and maintenance cost in the operation period is reduced, and an internal force analysis method for designing the structure of the type is provided.
一种13米跨径无铰缝空心板结构和设计方法，包括边梁、中梁、钢筋混凝土桥面铺装层、双层钢筋网、顶板、腹板、底板、翼缘、4Φs15.2预应力钢束Ⅰ、3Φs15.2预应力钢束Ⅱ；所述的边梁与中梁、中梁与中梁之间通过钢筋混凝土桥面铺装层连接成为整体。设计中将其边梁、中梁和钢筋混凝土桥面铺装层均采用空间梁单元模拟，并通过有限元程序分析计算。本发明可以改善空心板桥整体结构受力，在新桥设计中可以有效降低桥梁病害隐患,减少运营期间的管养成本，并且提出了进行设计此类结构的内力分析方法。
