T/CCTAS 147-2024 Design and Construction Specification for Asymmetric Diagonal Suspension Bridge on Highways
Basic Information
Scope
Main technical content: The overall mechanical behavior and local structural characteristics of highway asymmetric cable-stayed bridges are different from those of conventional cable-stayed bridges. The standard stipulates the basic requirements, materials, functions, overall design, structural design, structural analysis and calculation, construction, construction monitoring, quality inspection, etc. of highway asymmetric cable-stayed bridges, and is applicable to the design and construction of new bridges with a span of less than 300m and a ratio of side span to main span of less than 0.6 for single-tower asymmetric cable-stayed bridges, as well as double-tower asymmetric cable-stayed bridges with a ratio of side span to central span of less than 0.4. It plays a strong guiding role in further improving the design and construction of asymmetric cable-stayed bridges in highway and municipal engineering projects.
