Dictionary Thesaurus Idioms Encyclopedia Wikipedia Related to punching:punching shear,punching bags (pŭnch), An instrument for making a hole or indentation in some solid material or for driving out a foreign body in such material. [L.pungo,pp.punctus,to stick, to punch] ...
3.Longitudinal reinforcement in the plastic area provide punching shear capacity by its dowel stress instead of its axial tensile stress.通过对钢筋销栓力模型的分析,认为弯曲或弯冲破坏的混凝土板钢筋进入屈服,销栓力为零,钢筋几乎不能提冲切抗力;而对于高配筋率情况下的冲剪破坏钢筋的销栓力对混凝土板的冲切...
The present invention provides a reinforcement member for preventing punching shear stress, capable of enabling a range to which shear stress is applied to be widely extended by being formed in a plate shape and including a taper embedded into a slab on a head of a column. According to an ...
Underground parking structures often consist of flat slabs connected by columns, for which punching shear is often the most critical design criterion. In fire conditions, the punching load can increase due to restraint of the thermal curvature of the slab or due to the expansion of the columns....
Measured and analysed were the punchingshear stress, the value of vibration and the frequency spectrum under the working conditon of punch machine, and the shear, stress of the materials used to forge coins. 对冲压机工作状态下的冲剪力,振动量值和振动频谱及造币用材料的剪切应力进行了测试与分析。
Optional design with unsmoothed shear stress along the control perimeter that corresponds to the actual shear stress distribution in the FE model Determination of the load increment factor β via full-plastic shear distribution as constant factors according to EN 1992‑1‑1, Sect. 6.4...
The shear stress distribution on the punching shear failure Notation The following symbols are used in this paper: A parameters of material strain hardening; Apunch the total area of the punching shear failure face; c1 friction coefficient in the Mohr-Coulomb model; c2 shear resistance in the ...

(EPR). All the three developed models were used to predict (K Aci, K Ec2) using “characteristic strength of concrete in MPa” (Fcu), “aspect ratio of column” (L/B), “tensile capacity of shear reinforcement in kN” (Ash.Fy) and “the average pre-stressing stress in both ...
