Finite Element Analysis of Punching Shear of Reinforced Concrete Slab–Column Connections with Shear Reinforcement

چکیده
Shear reinforcement is one of the common measures used to strengthen slab–column connections. It can make joint’s load capacity increase. However, when connection subjected an unbalanced bending moment, reduction effect shear on moment worth investigating. Nonlinear finite element analysis was performed reinforced concrete slabs with for various moment-to-shear (M/V) ratios. The effects number and diameter different loading methods slab were investigated, as along a correction ACI-318 China Concrete Structure Design code GB50010 formula transfer coefficient. 3D modeling using appropriate types constitutive model concrete. damage plasticity parameters calibrated experimental results specimen. amount had certain contribution strength slab, but little effect. plate’s bearing decreased M/V increased. corrected coefficient demonstrates that positively correlated calculated values specified in are overly conservative.

Numerical Analysis of Punching Shear Failure of Reinforced Concrete Slabs
Nearly no load bearing behaviour of reinforced concrete members allows such varied interpretations and complex discussions as the shear behaviour. Especially the three-dimensional problem of the punching shear failure of reinforced concrete members is internationally discussed. Nevertheless up to now, there is no unified design approach or even an overall accepted design model. Especially for l...
متن کاملPunching shear strength of steel fibre reinforced concrete slabs
The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional methods of strengthening against punching, steel fibre reinforcement has proved to be an effective and viable alternative. The addition of fi...
