Background purpose

Static behavior Strand sheet

Background & Purpose

clear

Fatigue behavior

unclear

To make fatigue behavior clear

To analyze residual strength after 2milion fatigue load


Experiment result
Experiment & Result Strand sheet

Maximum load 90kN

Minimum load10kN

・Specimen

・Failure model

1layer Bending failure

Maximum load 250kN

Debonding occur at end of sheet

2layer Bending failure

Maximum load 260kN

Debonding occur at end of sheet


Experiment result4
Experiment & Result Strand sheet

Load-displacement at loading point of 1 layer


Experiment result5
Experiment & Result Strand sheet

Load-displacement at loading point of 1 2ayer


Experiment result6
Experiment & Result Strand sheet

Maximum load

Static After fatigue

1layer 278kN 250kN

2layers 315kN 260kN

Enough residual strength


Experiment result7
Experiment & Result Strand sheet

Strain of sheet


Experiment result8
Experiment & Result Strand sheet

Strain of sheet

The number of loads increase

Strain of sheet increase

Strain of sheet

1layer>2layer
