| Abstract: |
To investigate the effects of short stud arrangement on flexural behavior of steel-UHPC composite decks, a static bending test was conducted on a full-scale segmental specimen and a parametric analysis was executed based on a validated finite-element model. The test results showed that when UHPC crack width reached 0,10 mm, the measured strain of UHPC was 1568 με, accounting for 47% of the material ultimate tensile strain. And the corresponding nominal stress of UHPC was largely over the material cracking stress. The parametric analysis results showed that increasing stud spacing from 200 mm to 300 mm increased the UHPC cracking load by 9,7% because of a lower composite action; compared with the normal arrangement, studs arranged in groups with the same amount could increase the UHPC cracking load by 11,1% while maintaining the combined effect. However, this was under the condition that the steel and UHPC partially interacted. |
