Blue Eyes Intelligence Engineering & Sciences Publication Pvt. Ltd. Cost Effectiveness of Post- Tensioned and Reinforced Concrete Flat Slab Systems

Abstract — In a developing country like India the benefits of prestressing and particularly of Post-Tensioning are yet to be recognized. The inherent hurdle is undoubtedly the higher initial investment that is required from the clients. This has to be overlooked considering the significant benefits of Post-Tensioning and the high benefit-aspect ratio that can be advantageously procured. In the present study an attempt is made to compare the cost effectiveness of Post-Tensioned flat slab systems with respect to reinforced concrete flat slab system. Both the systems were analysed using SAP and MS Excel program was developed based on the design methodology. The results indicate that Post Tensioned flat slabs are cheaper than the RCC slab systems for all the spans considered in the present study
