Reliability analysis of suspension bridges against buffeting failure

A reliability analysis of suspension bridges against buffeting failure due to gustiness of wind velocity is carried out using the concept of PRA (probabilistic risk analysis) procedure. For this purpose, the bending stresses at the critical nodes of the bridge deck are obtained for buffeting forces using a spectral analysis technique and a finite element approach. For the purpose of reliability...

Geometric Nonlinear Analysis of Self-Anchored Cable-Stayed Suspension Bridges

Geometric nonlinearity of self-anchored cable-stayed suspension bridges is studied in this paper. The repercussion of shrinkage and creep of concrete, rise-to-span ratio, and girder camber on the system is discussed. A self-anchored cable-stayed suspension bridge with a main span of 800 m is analyzed with linear theory, second-order theory, and nonlinear theory, respectively. In the condition o...

Challenges in operational modal analysis of suspension bridges

Operational modal analysis is being increasingly used as an experimental technique to identify the dynamic properties of many types of large-scale constructed systems. The writers conducted such an experiment to identify the dynamic properties for the masonry towers of a landmark suspension bridge with the objective of providing data to validate and improve the reliability of a seismic evaluati...
