| Abstract: |
The second Jiaojiang Bridge is a composite cable-stayed bridge with the span arrangement of 70m+140m+480m+140m+70m. During the analysis, spatial grid model is adopted by the authors to undertake a research program focusing on the modelling and reinforcement design of the concrete upper plate of the composite box girder. The advantage of this model is that the stress results cover all the spatial effects including shear lag, statically indeterminate shear flow inside the side boxes and in the concrete upper plate. |
