A Master Digital Model for Suspension Bridges

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...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Jing Liu: Degradation Model and Security Analysis of Hangers of Suspension Bridges

The hangers of a suspension bridge is one of the most important stressed members, the thorough research of the deterioration during operation period and the security analysis after the degeneration of hangers is essential. This is the basis of the strategy of preventive maintenance of suspension bridges. Firstly, the paper studies the four stages of degradation mechanisms of sling and calculati...
