Design of Precast System of Construction for Multi Storied Buildings

Despite improvements in conventional construction techniques and material, building construction industry suffers from several issues like time delay, quality issues, higher costs, wastages, and pollution. In the immediate future, the industry is likely to shift to Pre- Cast methods of construction from conventional in-situ methods to overcome the above issues. Pre-Cast methods of construction are already in use in the industry but are restricted mainly to mass housing (as against custom architecture housing). Therefore, a novel Pre-Cast (Form finished) method of construction is sought to be developed which will be suitable for individual structures with custom architecture advantages. The method developed is to Pre-Cast the components in a factory. This will result in better quality control and testing. The method is also suitable for standardization and modular approach in construction which will result into cost saving. It also allows us to reduce project time. In the Pre-Cast construction, the design and construction of the joint between structural members is critical to the structural behavior of the overall assembly. In the present method the location of this joint is chosen to be in proximity to the point of contra flexure. Thus, the ductility of the beam-column joint (IS 13920, 2016 for ductile detailing) is also not compromised. The Pre-Cast assembled beam is tested for static loading. The performance of Pre-Cast assembled beam is also simulated using Finite Element Method. The Experimental results are compared with FEM simulation. It is concluded that the performance of Pre-Cast assembled beam is meeting all required criteria and good agreement with all the codal stipulations
