ABSTRACT The analysis and design of slabs are interactive area of research work. In the earliest of 20th century Reinforced Concrete floors or slabs were built on regular basis. But nowadays due to demand of economy and fast construction Hollow Core Slabs (HCS) have proven to be more desirable as compared to RCC slab. As we know if the construction time of any project increases it also increases the cost of construction. There might be an accountable difference in cost within a year of construction of same square feet of area. For this we really need to minimize the time without compromising the quality. There is wide range of structural element available in market with enhanced structural properties compared to conventional one. One of the elements which is widely used are the precast structural elements which are produced in factories with great accuracy and skilled supervision. Among this we have Hollow Core Slabs which are quick to setup and are generally cost effective. HCS units have good sound and thermal properties and long spans which is easy to achieve economically. Hollow core slabs are precast, prestressed elements generally used as flooring. They usually consist of continuous voids which run along the length to reduce the self-weight. The reduction in dead load of element reduces the depth of other structural elements. HCS are constructed in precast factories using low slump high strength pre-stressed strands.
