Abstract：Research purposes: This paper researches the design of a roof truss without columns according to the requirement ， such as astylar ， clearer ， more comfortable and so on in the rebuilding engineering of one railway station.
Research methods: Combined with the situation of the construction plot the major structure，whose plane size is 41 m x 400 m in the single-span complete coverage structure style，has no supporting column inside and only has 28 down-to-ground bracings at both sides. And space structure analysis software is adopted to do structure calculation.
Research results: By the practice of a new spatial structure system of latticed shell with bolt spherical joints and down- to-ground pipe truss，this paper provides some successful design experiences and special detail construction measures.
Research conclusions: The latticed shell with bolt spherical joints and down-to-ground pipe truss of the roof truss without columns can rationally embody the member efficiency and sufficiently display the architectonic effect. For structure in a massive figure，the influence of the temperature stress is remarkable. The structural stress performance under temperature stress can be significantly improved by the corresponding measures. The detail construction design was accomplished with the rational analysis methods，which ensures the structural safety and applicability.
