Experimental Analysis of 25 m Span Straight Guideway Girder
Jiao Jinhong， Chen Liang
Abstract：Through an analysis of the 25 m span straight guideway girder experiments,including the static state experiment,fatigue experiment and destruction experiment,this paper concludes that the 25 m span straight guideway girder is much safer for the project, and can provide a basis for the design of guideway girder in proctical engineering.
Key words：straddle monorail; prestressed concrete girder; experiment
