This article gives a primary analyze with high building diagrid structure which is a new style appeared in project recent years and discusses the disposal of the geometry, section and node design with high building structure. Study selects the two-way bias diagrid structure as a two-way bias network of emphases, analyze the effecting factor of lateral stiffness of the diagrid structure by response spectrum mode superposition method and establish mode in Etabs structure analyzing software for test results. Result of analyzing and derive ding show that for different aspect ratio there exist a optimal angel which can provide a most lateral stiffness and gives design methods for diagrid structure material displacement and material stress demand.Based on two-way bias diagrid structure study, article analyzes this structure style application evaluation on distorted spiral high buildings. We select vertical which have a excellent lateral stiffness as the base mode, and establish spiral diagrid structure high buildings by rotating floor. We use Etabs response spectrum mode superposition method for the actual project conditions in a typical analysis of the column to reverse the process of oblique angle, reverse angle, aspect ratio on the overall lateral stiffness of the structure. The results showed that the top floors of a square cross-section two-way bias network of tube structure in different aspect ratio of the overall situation, the overall degree of lateral stiffness with the increase in reverse, not weakened. And design the inclined column by changing the oblique section inclined column section size to improve the stress distribution optimization method for the engineering design theory.
