摘要: Abstract Crumb rubber concrete slabs and steel beams connected by single-headed studs were investigated in this paper. An accurate numerical analysis based on ABAQUS was developed to derive nonlinear material properties damage plasticity models of with four different contents reasonable contact algorithms. The reliability the verified our previous experimental work, an extensive parametric study conducted. results for stud nominal strengths compared those specified AASHTO LRFD EUROCODE-4. Furthermore, typical stress mechanism push-out test relationship tensile force bending moment that bears achieved. deformation proven be larger crumb concrete. Finally, effect welding defect studied systematically. show bottom is most dangerous one, especially ultimate slip ductility stud.
