It is used for the purpose of to free the way for electromechanical duct work. Hidden Beam their Uses, Advantages and Disadvantages, Hidden beam distribute loads imposed on the slab i.e. concrete . Probably the most significant disadvantage of CBCT is that it produces a worse contrast resolution compared to fan-beam CT, making it harder to view soft tissue. It is a reinforce concrete beam.it is also known as concealed beam, hidden beam or slab beam. Beams enclosed in a firerated duct. Types of Concrete and their Uses, Classification and Properties. Suspended ceilings do not last very long. What is Post-Tensioned Steel? It increases the uniaxial moment at the support of beam. Beam Bridges have a limited span and do not allow large boats or vehicles to pass underneath. It gives clearance of storey height or floor to floor height.
