Study on Behaviour of Castellated Beams with Externally Prestressed Condition

Abstract

Castellated beams offer a balance between structural efficiency and architectural aesthetics. They provide opportunities for creativity, innovation, and sustainability in construction projects, making them valuable components in the fields of engineering and architecture. Engineers and architects often use castellated beams to achieve both structural and aesthetic goals in their designs. In structural aspect, the behaviour of castellated beam serves less than the service provided by solid beam. Though this of obvious, the improvement of behaviour of castellated beam should be concentrated. Here an attempt has been made experimentally to use external prestressing to enhance castellated beam behaviour. Four beams are fabricated and tested. The castellated beam with prestress behaves extremely good in all aspects can be noted from the results. Finite element analysis is also attempted for the experimental beams and discussed in this paper.
