This lecture covers the principles and functioning of cable-stayed systems, how to solve them using graphic statics, and the different cable configurations. Starting with a simple wooden bar suspended by inclined chains, the instructor demonstrates how to analyze the equilibrium of such systems. By isolating subsystems and analyzing the forces acting on them, the lecture progresses to more complex structures with multiple cables. Different cable configurations, such as fan-shaped and harp-shaped, are discussed, highlighting the varying forces and lengths of cables. Real-life examples like the Nantes transporter bridge and the Millau Viaduct showcase the practical applications of cable-stayed systems. Through graphic statics, the lecture illustrates how these systems can be effectively analyzed and designed.
