Study on the Closure Technology and Closure Sequence of the Low Tower Cable-Stayed Bridge

Low Tower Cable-stayed Bridge is stress complex,requires high construction skills,and is a statically indeterminate structure.Recently,Low Tower Cable-stayed Bridges are developing rapidly in China.The paper summarizes the development of Low Tower Cable-stayed Bridges.The construction process of a Low Tower Cable-stayed Bridge is simulated based on finite element method.It can be concluded that the change of the stress and the deflection in the different condition of the closure order control the structure system transformation,which will be instructive to the design and construction of bridges of the same kind.
