钢筋混凝土或预应力混凝土单孔简支梁在架设以后用连杆把它们串联相接,由于连杆在荷载作用下似铰的作用,而称为铰接简支梁桥。近年来,我院将这种桥式运用到新建铁路直线桥梁上对改善桥墩受力状况,使桥墩轻型化有显著效果。本文着重介绍铰接简支梁桥墩设计的有关问题,供参考。 Reinforced concrete or prestressed concrete single-hole simple-supported beams after the erection of the connecting rod to connect them in series, due to the role of the link under the load like hinges, and called the hinged simply supported beam bridge. In recent years, our hospital will be such a bridge to the new railway bridge to improve the bridge pier stress conditions, so that the pier has a significant effect of light. This article focuses on the design of hinged simply supported beam piers for reference.
