Modeling the post shear failure behavior of reinforced concrete columns
… detailed columns will only experience axial failure after shear failure and subsequent lateral shear strength degradation have occurred. Therefore, column shear failure and degrading behavior must be modeled accurately before axial collapse algorithms can be properly implemented. Furthermore, …

Modeling the High Strain Rate Tensile Response and Shear Failure of Thermoplastic Composites
… shifted using tTSP. Similarly, through-thickness shear response of UHMWPE composites is of interest to support computational modeling of impact damage. In this study, punch shear testing of UHMWPE composites is conducted to determine shear properties. Two test fixtures, one allowing, and one …

An investigation into the punching shear failure in R.C. waffle slabs subjected to concentrated load
… subjected to concentrated loads. The punching shear failure inside waffle slabs has not been thoroughly investigated and this is also reflected in the current code of practice, which, in the main, relates the design of punching shear in waffle slabs to that in solid slabs. In this study, both …

An experimental study and finite analysis of punching shear failure in steel fibre-reinforced concrete ground -suspended floor slabs
… using steel fibre-reinforcement on the punching shear behaviour of ground-suspended slabs with internal columns. The main objectives of this research were to develop a constitutive model for steel fibre-reinforcement (SFRC), to study experimentally the punching shear behaviour of SFRC with no …

Modelling the Post-Peak Response of Existing Reinforced Concrete Frame Structures Subjected to Seismic Loading
… stringent seismic codes are often vulnerable to shear or flexure-shear failure followed by axial failure. Thus, such substandard R/C structures are susceptible to vertical collapse, which pertains to the exceedance of vertical resistance of columns and connecting beams and can lead to the whole …

Shear strength of reinforced concrete wall-beam structures: upper- bound analysis and experiments
… presents rigid-plastic methods of analysis of shear failure in reinforced concrete (R. C.) wall-beam type structures when subjected to in-plane loading. The upper-bound approach is emphasised. Present shear design practice (e.g. BS8110:1985) relies much upon empirical solutions, but it is …

Behaviour and Analysis of Strain Hardening Fiber Reinforced Cementitious Composites Under Shear and Flexure
… quantifying the contribution of concrete to the shear strength of concrete members. By introduction of novel cementitious material, a much greater need to develop a standard to treat the concrete in a systematic manner is felt. In this thesis, an alternative framework of analysis to interpret the …

Characterization of Punching Shear Capacity of Thin Uhpc Plates
… and contained no reinforcing steel to resist shear. The lack of steel reinforcement allowed for the possibility of a punching shear failure to occur from the application of a point load such as a wheel tire patch load. The model and optimized section served as the foundation for this research, …

Evaluation of behavior and the radial shear strength of a reinforced concrete containment structure
… interaction. A possible mode of structural failure of containments subjected to high pressures is by radial-shear failure at the wall-basemat connection. Although the containment model showed no sign that such a failure was imminent when the test was stopped, if the internal pressure had …

An integrated peridynamics-finite volume based multi-phase flow, geomechanics and hydraulic fracture model
… a natural fracture (NF) is investigated. Remote shear failure of the NF due to the pororelastic stress changes caused by the propagating HF are considered. Consistent with the experiments, the remote shear failure is shown to result in the bending of the HF towards the NF before intersecting with …

Resistência ao esforço cortante de peças de concreto armado de seção transversal circular
The results of an experimental research on the shear failure of reinforced concrete members with circular cross-section are presented. Eight simply supported beams with a 3,0 m span and a 0,4 m diameter cross-section were tested by loading them with two symmetrical concentrated forces. The variable …
