I want to know about the deep beams & would like to give seminar

Deep beams are structural members loaded as simple beams in which a significant amount of the load is carried to the supports by a compressive force that combines the charge and the reaction. As a result, the strain distribution is no longer considered linear, and the shear deformations become significant in comparison with pure bending.

Horizontal load-bearing floor slabs, short-section beams carrying heavy loads and transfer beams are examples of deep beams. The deep beam is a beam having a large depth / thickness ratio and a depth ratio of the cut width less than 2.5 for the concentrated load and less than 5.0 for the distributed load. Due to the geometry of the deep beams, their behavior is different with the slender beam or intermediate beam.

Design is based on the ACI Ultimate Force Design Method and applies to those flex members that have a span to depth ratio of less than 4.0. The flexural reinforcement is designed taking into account the reduced lever arm due to the non-linearity of the distribution of the deformations.

Deep beams play a very important role in the design of mega and small structures. Sometimes, for architectural purposes, buildings are designed without using any column for a very large stretch. In such a case, if ordinary beams are provided they can cause failures such as bending failure. To avoid this problem of the construction of some very long corridors etc. The concept of deep beams is very effective and durable. But there are also some minor problems with building deep beams, so leave.
