This paper takes Songhua River Bridge construction as an example,based on the geographical environment and climate conditions of this project,analyzes in detail the large cantilever stability of this bridge under the wind load and offset load in winter,puts forward several load combination loading methods,and introduces the safety measures taken for this bridge.

It showed that single support bridge could not appear bearing disengaging under whether single trace or population offset load during its operation stage.

With reference to the Puyangjiang double-tracks railway continuous beam bridge in the electrified speed-raising of Guangzhou-Ganzhou railways engineering,this paper analyzes the torsional response of box beam in the partial load of dynamic and static loads test.

The results show that the insufficiency of carburized depth,decarburization on the surface layer and the coarse grain in carburized layer of the gear are the main factors to cause the failure of the gear,as well as the bias load running of the gear during service.

Analysis and study on the FEA of rolling mill bearing under deflected load;

Failure theory and experiment of the tray in roadway roof with eccentric load;

Owing to construction,the FRP bolt is often under eccentric load which is harmful for bolt by theory analysis.
