| 摘要： | Finite-element analyses (FEA) of reinforced concrete slab-column connections with shear reinforcement are presented and discussed. Ultimate loads and crack patterns are shown and compared to the experimental findings. The damaged plasticity model in ABAQUS, previously calibrated and validated on tested slabs without shear reinforcement, is adopted to properly simulate the behavior of slab-column connections with shear reinforcement. Four interior slab-column specimens were tested under vertical loading applied through the column. One slab specimen was without shear reinforcement, while the other three differed in the amount of the shear bolts. The objective of this paper is to propose a novel numerical modeling strategy for simulating and analyzing shear reinforced slabs with shear bolts. For that purpose, in the numerical analyses, four different approaches for modeling the shear bolt are introduced and described. Discussion and comparison on the predicted failure loads from the design codes and models in conjunction with the experimental and numerical data, are presented. Finally, a parametric numerical study is conducted, where the rectangular and the radial shear reinforcement arrangements are compared. |
