Research on Secondary Moment of Prestressed Slab-Column Structure
In this paper, beginning with the mechanism of secondary moment, the calculated difference of secondary moment between slab-column structure and skeletal structure is indicated, and the secondary moment distribution of prestressed slab-column structure is provided by finite element analysis. The effect of edge beams setting or not and arrangement types of prestressing tendons on the magnitude and distribution of secondary moment is analyzed, and the magnitude relation between secondary moment and external load moment is compared. It can be served as reference to understand the distribution of secondary moment and design slab-column structure reasonably.
