The test and calculation analysis of temperature stress of a frame structure with complex plane and super-length span are introduced in detail. Some useful data are presented and can be referred in design. The results show that the temperature deformation control the behavior of super-length frame structure, and some measures, such as prestresslng, heat insulation, may be taken for the structural security.
Keywords: concrete structure; super-length structure; temperature stress; dector; test
