摘要：

With the application of super high and large-span floor structure, the design of the formwork support system should meet more strict demands. This paper introduced a steel column-tube support system for the formwork of the large-span and multi-layer gymnasium in Heilongjiang University of Chinese Medicine. The steel column-tube support system can not only unload step by step, but also promote productivity of labor and reduce engineering cost evidently. The performance of the support system of large-span floor structure were summarized and analyzed firstly. Then, this paper elaborated the design and construction means of the support system. Finite element model was established to analyze the bearing capability of the structure when the floor was set the steel column in the position of shear pole. The results show the support system has the features of high bearing capacity and security which can meet the requirements of the design code.
