For buildings larger than 15 to 20 floors, a system with a clean rigid frame is not adequate because it does not provide
the required lateral rigidity and causes excessive deflection of the building. These requirements are met in two ways. By
introducing the effective section such as beam, column etc in to the structure. This increases the stability and rigidity of the
structure, and also limits the requirement for deformation. Now days the composite beam is also used for tall buildings. The
Paper present the short summery report of use of various beam elements in building to get the effective out comes to sustained
under the lateral forces response.
