Truss cable-stayed bridge
The invention discloses a truss cable-stayed bridge which is mainly composed of main beams (1), main towers (2) and inclined trusses (3). The inclined trusses (3) are arranged on the two sides of the main tower (1), the two ends are connected with the main tower (2) and the main beam (1) respectively, and the truss height is gradually increased from top to bottom. Due to the fact that the inclined trusses (3) are large in tension and compression rigidity and good in stability, the calculation span of the main span can be effectively reduced, the main span is approximate to a multi-span continuous beam, and the inclined trusses (3) participate in bending resistance, so that the bending moment peak value of the main beam (1) is reduced. And the inclined truss (3) participates in pressure resistance, so that the axial force of the main beam (1) is greatly reduced, and the steel consumption of the main beam (1) can be saved. Therefore, the truss cable-stayed bridge is a novel bridge with excellent mechanical property and economical efficiency.
本发明公开了一种桁架斜拉桥，主要由主梁（1）、主塔（2）和斜桁架（3）组成；斜桁架（3）布置于主塔（1）的两侧，两端分别与主塔（2）和主梁（1）相连，且桁高自上而下逐渐增大。由于斜桁架（3）自身拉压刚度大、稳定性好，因此可有效减小主跨的计算跨径，使其近似成为多跨连续梁，且斜桁架（3）参与抗弯减少了主梁（1）的弯矩峰值；又因为斜桁架（3）参与抗压，所以主梁（1）的轴力也大幅减少，从而可节省主梁（1）的用钢量。故桁架斜拉桥是一种力学性能和经济性优良的新型桥梁。
