What is the purpose of haunch in box culvert?

generated are accumulated at the corners of box culvert. Thus, there is a need of haunches that provide a slight bend at the corners so that the stresses are not accumulated and make the structure vulnerable to fail or deform. Hence, haunches play an important role in withstanding the applied loads and forces.

What is the purpose of haunch?

A haunch takes the variation gradual. A culvert is made to pass water, haunch is provided at bottom and top corner,( which is generally 1:1 slope). 1-it is provided to counteract the shear force to reduce the chance of shear failure. 2-it also distribute the hydraulic force of water that passes through it.

What is a haunch beam?

A haunch beam is a 1D member whose cross-section varies along the length of the 1D member. It is also possible that a part of the 1D member is of a constant cross-section and only the remaining part contains a haunch. Therefore, the list of haunch beam parameters may be rather long.
