Abstract Research purposes: Research on the key technology of the rotational structure design of T-shape rigid frame bridge on Zhangshi expressway has been conducted. The problems on design, manufacture and construction techniques of the spherical horizontal-rotational structure have been solved.
Research methods: Combining with the theory of materials mechanics and elasticity mechanics, the forcing condition on the contacting surface under the stationary condition should be calculated out initiatively. Then calculation imitating real condition has been done with the large general space finite element programmer.
Research results: According to the research of rigid frame's stress, strain and stability, a whole set of method of design and calculate have been summarized. The main calculation method and content of the rotational structure of highway T-shape rigid frame bridge have been showed in this paper, too.
Research Conclusions: During the rotational structure design shape and dimension of the rotational plate should be chosen according to the character of the rotational structure. The problems of the stress and strain on the connecting surface of rotational plate should be solved by calculation and analysis with the structure analysis programmer, then the economic and reasonable rotational structured should be worked out.
