摘要：This work includes the design and estimate for flat slabs of various spans, ranging from 6.0 m to 12.0 m,by reinforced concrete cement and prestressed concrete techniques. For smaller spans, associated with normal buildingworks, prestressed concrete construction becomes too cumbersome, irrespective of the economics involved. Intensity ofassumed loading is kept sufficient enough, so that the factored bending moment will be comparable to that developingin cases of commercial buildings. Post-tensioning is preferred as it is in vogue, in construction of large span slabs.All structural costs, floor framing is usually the largest component. Likewise, the majority of a structure’s formworkcost is usually associated with the horizontal elements. Consequently, the first priority in designing for economy isselecting the structural system that offers lowest overall cost while meeting load requirements. Post tensioning is thekey to cost-effective multifamily construction. In addition, post-tensioned structures can be designed to have minimaldeflection and cracking, even under full load. Thinner floors provide lower building weight, which creates acorresponding reduction in other structural elements. There are also some associated labour and time savings
