摘要
通过不同跨度的开口型压型钢板-混凝土组合楼板的静力试验,研究该组合楼板的裂缝分布、破坏特征和滑移规律等情况。试验结果表明:8个试件均发生纵向水平剪切黏结破坏;端部栓钉可以有效减少端部滑移。采用有限元软件ABAQUS对大跨度试件的黏结滑移性能进行模拟分析,分析结果与试验结果吻合良好。在此基础上,通过改变参数分析大跨度试件的滑移性能影响因素。分析结果表明:增大组合楼板高度和减少压型钢板厚度均可增强试件的抗滑移性能;随着剪跨比的增大,组合楼板的延性提高,端部滑移降低。
Based on the tests of the opened profiled steel sheeting-concrete composite slab,crack distribution,failure modes and slippage distribution were studied.The tests results showed that the longitudinal shear failures occurred in8 specimens and the studs could decrease slips.Nonlinear finite element models were established to analyze the bond property of specimens using ABAQUS.The results from the numerical analysis agreed well with the experimental results.On the basis of which,some factors influencing the shear-bond property were studied by changing some parameters.It was found that both the increasing of the thickness of slabs and the decreasing of the thickness of profiled steel sheeting could improve slipping-resistant property.As shear span ratio increased,the ductility of slabs could be increased and the end slip was decreased.
