It can be used in the construction of precast and prestressed concrete slab floor construction.Ĭastellated beams were most commonly used for parking garages because of their long-span capabilities.The beam can be designed asymmetrically in case of increased loads.The overall cost of the structure will be reduced as castellated beams are more economical.It minimizes the floor vibration issues.It has a high stiffness-to-weight ratio.Castellated beam requires low maintenance.The installation cost of castellated beam is 10% less compared to concrete beam.Handling of the beam is easy due to the lighter weight.Installation is fast and easy as the span of the beam is longer.The depth of the beam can be increased up to 66 inches.
Castellated beams have a higher moment carrying capacity with no added steel.Castellated beam lowers the floor-to-floor height as MEP lines are passed through the web openings.It allows natural light into the structure.A castellated beam enhances the aesthetic appearance of a structure.The length of the castellated beam can be extended up to 90 ft.The weight of the beam can be lowered up to 40% when compared to the wide flange steel beam.This beam can be customized from section to section thus, the castellated beam is extremely versatile. The physical characteristics of the castellated beam can be changed to achieve several goals.The design and erection of the castellated beam are elegantly simple.
Unique split fabrication of beam gives the ability to lower the weight of the top half of the beam, thus increasing the load-carrying capacity while minimizing the weight of the beam. The length of the beam can be increased up to 28 m which makes the castellated beam optimal for wide-span and wide-open bay designs. They have 40% more moment-carrying capacity with no added steel. As a result, castellated beams are highly efficient when it comes to enhancing the load-bearing capacity. The principal property of a castellated beam is that we can increase the depth of the beam without increasing its weight. The properties of castellated beams are: 1. The Castellated beam name is derived from the Latin word "castellatus" meaning "built like a castle having regular openings in walls like a castle." These beams were designed as structural channels to improve the depth and strength of the beam without adding more material or weight.Įngineers faced steel shortages after WWII, and they discovered that castellated beams were cheap to build and had an excellent strength-to-weight ratio.Īs a result, castellated beams have been the preferred building solution since the 1950s and were commonly used in Europe to decrease the cost of steel structures due to the low ratio of labor cost to material cost.
