Tied-arch bridge with net-shaped suspenders
A tied-arch bridge with net-shaped suspenders comprises an arch rib, a tie bar and a plurality of inclined suspenders; the inclined suspenders are arranged between the arch rib and the tie bar and arearranged in a net-shaped structure; the arch rib is of an arc structure. The inclined suspenders are arranged in a net-shaped structure, the inclination angles of the suspenders are larger, the number of the suspenders is larger, the spacing distance is smaller, and the number of times of intersection in a plane is larger, and compared with a traditional vertical suspender tied-arch bridge and atied-arch bridge of a Nelson suspender system, under the same span and load working condition, when the distribution lengths of loads on the tie bar are the same, the load can be transmitted to the arch rib in a longer range, the tied-arch bridge with the net-shaped suspenders is more reasonable in stress, and engineering investment is saved. Under the action of the same vertical live load, the bending moment of the arch ribs and the tie bar of the tied-arch bridge with the net-shaped suspenders is smaller, the structural stress is more reasonable, vertical deformation and beam end corners ofan arch bridge can be greatly reduced, and the material quantity and the construction cost are obviously saved.
本发明公开了一种网状吊杆的系杆拱桥，包括拱肋、系杆和若干根斜吊杆；斜吊杆设置在拱肋与系杆之间，所有斜吊杆呈网状结构布置；拱肋呈圆弧结构。斜吊杆呈网状结构布置，吊杆倾斜角更大、数量更多、间距更小、平面内交叉次数更多，与传统竖直吊杆系杆拱桥和尼尔森吊杆体系的系杆拱桥相比，相同跨度和荷载工况下，当荷载在系杆上的分布长度相同时，可将荷载传递到更长范围的拱肋上，网状吊杆的系杆拱桥的受力更加合理，节约工程投资；在相同竖向活载作用下，本发明的网状吊杆的系杆拱桥的拱肋和系杆的弯矩更小，结构受力更加合理，还可以大幅度减小拱桥的竖向变形和梁端转角；明显节约了材料数量和工程造价。
