Probability-Based Research on Sensitivity of Saddle-Shaped Cables Suspended

Performance-based structural analysis is the main trend of the future development of engineering design; probability-based sensitivity can reflect the importance of different parameters in the structural performance-based design. Therefore based on the response surface method, the reliability analysis program has been established, within which the sensitivity analysis of different parameters, such as the prestress, cable sectional area, cable strength and elastic modulus of saddle-shaped cable suspended, was conducted. And the corresponding sensitivity coefficient has been given, which can not only be used as a reference to the design of structure, but also can check the rationality of the structure design.
