Abstract
The concrete open-web sandwich slab is composed of the vierendeel girders intersecting each other. The vierendeel girder are composed of the upper rib, lower rib and shear key. The upper and lower rib mainly bear the axial force, and the shear keys mainly bear the shear force. A double scalar elastic damage constitutive model considering shear damage was derived to accurately simulate the mechanical property of the shear key in which one scalar reflected the volume damage, and the other one reflected the shear damage. The damage constitutive model in the study, the uniaxial tension and compression damage constitutive model (GB50010 (2015)), and the double scalar elastic damage constitutive model of tension and compression (Liu (2021)) were compared by simulating the shear key. The results showed that the elastic damage constitutive model proposed in the study can be used for the mechanical property analysis of the shear key and can better evolve the damage development of the shear key. The damage constitutive calculation model can be provided for the analysis of the vierendeel girder and the open-web sandwich slab.
