Cable Force Optimization Method in Two Stages for Spatial Cables
Applied Mechanics and Materials, 2013To get the ideal cable forces of the arch bridge with spatial oblique cables,Rigid Support Continuous Beam Method and Rigid Suspender Method are discussed.The results show that the former is unsuitable for the spatial structure with smaller horizontal stiffness,and the latter does not consider the elastic deformations of the cables.An improved cable ...

Optimum Cable-Force Adjustments in Concrete Cable-Stayed Bridges
Journal of Structural Engineering, 1995Two kinds of errors are frequently encountered during the construction of cable-stayed bridges: one is force-application error in the jacking cable forces, and the other is geometry error in controlling elevations of the girders. These errors are normally kept within the prescribed tolerances by adjusting cable forces.

Rating Independent Cable Circuits in Forced-Ventilated Cable Tunnels
IEEE Transactions on Power Delivery, 2010Over the last decade, there has been a notable rise in the number of forced ventilated cable tunnel schemes in the U.K., with new construction at transmission and distribution levels. The ability to accurately calculate continuous and emergency circuit ratings for these installations is vital in ensuring that their full operational benefit can be ...

Research on Force Performance of Cable Breaking on Cable-Stayed Bridges
Applied Mechanics and Materials, 2014The cable is the important force component of the cable-stayed bridges. The primary damage of cable is the corrosion which cause cable fracture. Local cable breaking lead to bridge force redistribution and have a certain impact to the mechanical characteristics of cable-stayed bridge, which affects the safety of bridge.

Cable force monitoring and prediction for cable group of long-span cable-supported bridges
Journal of Civil Structural Health Monitoring, 2018Cable force monitoring is an essential and critical part of structural health monitoring for long-span cable-supported bridges. Considering economical and efficient issues, the accuracy and quality of safety assessment depend considerably on a reasonable cable-monitoring scheme, especially the number and locations of limited sensors.

Calibration of initial cable forces in cable-stayed bridge based on Kriging approach
Finite Elements in Analysis and Design, 2014Although optimization methods are useful in the preliminary design of cable-stayed bridges for sizing of components and getting optimal bridge configurations, further fine-tuning is invariably conducted in the detailed design thus affecting various sensitive properties such as the deck profile and cable forces. The zero-displacement method that adjusts

Force-closure analysis of 6-DOF cable manipulators with seven or more cables
Robotica, 2009SUMMARYA cable manipulator controls its end-effector by a number of cables. If the cables can balance any external and inertia wrenches at a certain pose of the end-effector, the cable manipulator is said to have a force-closure at this pose. Since a cable can work only in tension, the force-closure at a specific pose may not exist.

Cryostability in force-cooled superconducting cables
IEEE Transactions on Magnetics, 1979In past experiments with force cooled NbTi cabled conductors we discovered that cryostability was essentially independent of coolant velocity. In order to verify these results we performed experiments using a 3m long cable with a Nb 3 Sn superconductor. The paper presents our new experimental results in comparison with previous data.

Optimization of Cable Force of Extradosed Bridges
Applied Mechanics and Materials, 2014In order to solve structural optimization problems in the past, it is necessary to integrate structure analysis software and optimization software. Since structural analysis has been the only function considered when developing most of structure analysis software, they suffer from closeness of system.
