为提升超大跨径桥梁结构的空间刚度,将三维空间索网引入超大跨径桥梁设计中,开展三维空间索网桥梁的构形研究.引入三维空间索网设计元素,可提升超大跨径桥梁的景观效果,同时,三维空间索网可大幅提高超大跨径桥梁的抗侧刚度和抗扭刚度,增强超大跨径桥梁的抗风稳定性.相关研究成果可为类似桥梁的设计提供借鉴.
Discussion on Application of Three-dimensional Cable Network in Bridge Structure
In order to improve the spatial stiffness of the super-long-span bridge structure,the research introduces the three-dimensional cable network into the super long-span bridge design,and carries out the configuration research of the three-dimensional cable network bridge.The introduction of three-dimensional cable network design elements can improve the landscape of the super long-span bridge.Meanwhile,the three-dimensional cable network can greatly improve the lateral stiff-ness and torsional stiffness of the super long-span bridge,and enhance the wind-resistant stability of the super long-span bridge.The relevant research results can provide reference for similar bridge design.
