| Abstract: | Take the segment No. 0 of a long span continuous rigid frame bridge as the research object, the Large finite element software midas FEA was applied to establish the solid finite element computational model of segment No. 0. In the construction process, the maximum double cantilever stage of construction and the maximum bending moment state both with the maximum shear state are considered as the control condition of calculation, made the spatial stress analysis of segment No. 0 by extracting the most unfavorable internal forces in the Integral model. Some conclusions are drawn to provide reference for the design and construction of segment No. 0 of similar project. |
