Tensile strength

  Previous topic Next topic  

 

Once the tensile forces in the reinforcements are known Ti, the armatures section b x t is determined. For metallic bars or strips with allowable stress equal with:

 

we have:

 

RotturaBS_EN

 

 

 

 

 

 

 

For geotextiles a problem that occurs in that the fabrics resistance varies from one producer to another. From available ones select one where:

 

(Strip length b ) x (resistance per width unit) Ti

 

rottura geosintetico_EN

 

The allowable resistance used for sizing is:

 

The unique safety factor (FS) is the combination of: Fs joint, Fs chemical, Fs biological, Fs environmental damages

 

FS = FSjoint × FSchemical × FSbiological × FSenvironmental damages
