Effect of boundary conditions on the estimation of suspender tension;

A new type strand suspender with extrusion is adopted in Liuzhou Wenhui bridge.

The main bridge of Liede Bridge in Guangzhou City is a single tower self-anchored suspension bridge and the model testing was required to be made for the bridge in order to check the load transferring and fatigue performance of the suspender anchor boxes of the bridge.

Length amending of straddle suspender cable in main cable clip;

Combined with practical engineering,the author analyzes the installation construction technology and construction machine of air-cooling platform and the selection of wind rope and sling,illustrates the setting of construction machine,upper pavement and ground anchor,introduces its construction orders and methods,and shows that air-cooling unit would has extensive developing prospect.

The application of a sling structure scheme used in a long span overhanging air yard and the items which should be considered in the design and the construction are mainly analysed and discussed.

Based on thinking over the extension of the slings and the hooks movement,We put forward the precise calculation method of the internal force of the slings and the status of the lifting hooks when lifting heavy eccentricity object using the double lifting hooks.

Experimental study on concrete-filled steel tube tied-arch bridge with CFRP hangers;

The construction stages of the main cable include catwalk erection, wire stranderection, cable bands and hangers installation, protection of the main cable, etc.
