Currently, many owners and consultants prefer to use post-tensioned PT slab systems in multi-storey buildings due to their considerable savings in materials, labor, and time. On the other hand, many contractors still use the traditional RC flat slab systems due to their simple construction process. This research focuses on the comparison between the two systems taking into consideration: cost, time, and structural behavior. Detailed cost and time analysis is performed for each system considering all construction resources. The analysis and design of the buildings are conducted using many structural and project management computer programs. These include ETABS, SAFE, RAM, REVIT, and Primavera. The results indicated that, PT systems provide significant savings for spans larger than 6 m. The structural analysis of both systems also showed that PT slabs are more effective in resisting seismic straining actions. |
