Theory and case analysis of PC cable-beam structure

The shape of cable in PC cable-beam structural system was determined. The whole process analysis of the stability of PC cable-beam structural system was conducted by using Ritz method. Based on the stability analysis, the stability formulas of PC cable-beam structure and the calculation method of the member's internal force pressure and cable segment's prestress in a certain unit were presented. Make a specific analysis on the design process of PC cable-beam structure through a design calculation example. Provide reference for the design of PC cable-beam structure.
