The punching shear problem of circular reinforced concrete slabs is studied, based on a layered finite element model, in which a simple shear distortion mechanism can be incorporated for nonlinear analysis. The transverse resulting shear force is taken into account to include the possibility of punching shear failure in the slab. Concrete behavior under the biaxial state of stress is represented by a nonlinear constitutive relationship, which incorporates tensile cracking at a limit stress, tension stiffening and shear retention effects for cracked concrete, and the strain-softening phenomenon beyond the maximum compressive strength. The steel reinforcement is represented by a bilinear strain hardening model. The analyses show that the transverse shear deformation effect has a significant influence on the thick reinforced concrete slabs and the concentrated load condition. The contribution of transverse shear deformation decreases with tensile cracking and compressive yielding of concrete.A good agreement between the analytical results and the experimental results of reinforced concrete slabs with normal reinforcement ratios under the punching loading has been obtained.

本文采用分层有限单元模型,并考虑剪切变形的影响,研究钢筋混凝土圆板的冲切问题。混凝土的非线性本构关系,则考虑受拉开裂、开裂后的拉伸加强效应和剪切折减系数以及屈服后的应变软化现象。钢筋以双线性应变硬化模型表示。分析表明,横向剪切变形对钢筋混凝土厚板及集中荷载的影响很大。承受冲切荷载的钢筋混凝土板的分析结果与试验数据对比,表明两者符合良好。

The various properties of amphoteric starch was investigated. The retention effect of the amphoteric starch as a retention agent in papermaking was paid attention to. It was found that the retention rate of amphoteric starch is higher than those of cation or anion starch, and is similar to polyacryamide. The amphoteric starch is a sood retention aeent.
