Abstract:

The use of post-tensioned flat slab is increasing widely, due to its advantages over traditional concrete. These slabs have been proved to be the most economical when compared to the RCC slabs. As these slabs are very easy to construct, Post-tensioned slabs are preferred for industrial, commercial and residential floor slab construction. Majorly because of the relatively thin slab depths, lighter in weight and smaller floor to floor heights, Post-tensioned slabs have been used for such construction. In post-tensioned slab high strength tensioned steel strands are used to compress the slab, keeping the majority of the concrete in compression. This gives a very efficient structure which minimizes material usages and decreases the economic span range when compared to reinforced concrete. By the study of literature in the research areas of Post-Tensioned Slab technique, some secondary moment effects are observed in the analysis of this slab. These effects combine with lateral loading causing critical issue in design of slab. The behaviour and response of flat slab and Post tensioned flat slab during earthquake is an important aspect which needs to be explored. The main objective of this paper is to give a review on the response and behavioural properties of Post-tensioned flat slab during earthquake and compare with normal flat slab.
