Why is Punching Shear Failure also called Two Way Shear?

Punching shear failure is a brittle failure & hence dangerous. Punching shear failure in slabs is quite common. Punching shear in footing is also important to attend to.
This video explains what is punching and punching shear failure in a very simple way and also explains why punching shear is also called a two-way shear. In fact, the punching stress acts in 2 different planes and hence the name. It is clearly explained in the video.
To summarise the video contains the below listed explanations.

Punching shear is called 2-way shear partly because it is generally associated with point supports in 2-way slabs, and partly to differentiate it from one way shear in that punching shear applies around a point support and one way shear applies along a line. Punching shear can apply in a slab that is reinforced and bent in one direction if a point load is applied in a concentrated location so it is not strictly a phenomenon of 2-way slabs.

Ah! I now understand. Thanks for a very clear explanation of this phenomenon.

Very simple..

Thank you 🙂

Then what is the difference between one way and two way shear?
I know that the distance of d from coloum face for one way shear...here I asked you the difference in real life structure?

[@CIVILERABangalore]

Thats the normal shear force

[@billj5645]

One way shear would normally be associated with a slab that is reinforced on one direction and spanning only in that direction. One way shear applies along a line such as when the end of a slab is supported along its width by a beam or wall. Two way shear typically applies around a point support and not along a line support.
