Recoverable continuous rigid frame bridge system based on energy dissipation straining beams
According to the recoverable continuous rigid frame bridge system based on the energy dissipation straining beams, main beams are supported above a bearing platform through four-limb lattice piers, and piles are arranged at the bottom of the bearing platform; in the four-limb lattice piers, lacing bars are arranged between the concrete-filled steel tubular columns in the transverse bridge direction, and energy dissipation straining beams are connected with the concrete-filled steel tubular columns through square steel sleeve joints in the longitudinal bridge direction. The energy dissipation straining beam comprises a steel top plate, a steel bottom plate and a corrugated steel web perpendicularly arranged between the steel top plate and the steel bottom plate. In the square steel sleeve joint, a square sleeve is connected to a concrete-filled steel tube column in a sleeving mode, an upper cover plate and a lower cover plate are arranged at the upper end and the lower end correspondingly and welded to the square sleeve and the concrete-filled steel tube column correspondingly, square end plates are arranged on the outer wall of the square sleeve correspondingly, and core penetrating bolts penetrate through the concrete-filled steel tube column and are connected with the square end plates through bolts; and the other end of the stiffening rib end plate is connected with the steel top plate or the steel bottom plate. The method has the advantages of being good in stress performance, good in economical efficiency, high in spanning capacity, fast in post-earthquake recovery and low in cost.
本发明公开了一种基于耗能系梁的可恢复连续刚构桥体系，其主梁通过四肢格构墩支撑在承台上方，桩设于承台底部；四肢格构墩中：缀条沿横桥向设于钢管混凝土柱之间，耗能系梁沿顺桥向通过方形钢套筒节点连接钢管混凝土柱；耗能系梁包括钢顶板、钢底板和垂直设于两者之间的波形钢腹板；方形钢套筒节点中：方形套筒套接于钢管混凝土柱上，上盖板和下盖板分别设于上下两端，均分别与方形套筒和钢管混凝土柱焊接，方形端板分别设于方形套筒的外壁上，穿芯螺栓贯穿钢管混凝土柱并与方形端板螺栓连接，加劲肋端板的一端连接方形端板，另一端连接钢顶板或钢底板。本发明具有受力性能好、经济性好、跨越能力高以及震后恢复快成本低的特点。
