Phy&ical and technical characteristics as well as the design procedures of the prestressed precast hollow core slab and wall elements are studied. It is intended to present for the convenience of practicing engineers, a general guideline and comprehensive information about the hollow core slabs and walls used in both residential and commercial buildings. After a brief introduction to the precast and prestressed structures, physical and technical characteristics such as thermal insulation, acoustical parameters, fire resistance, manufacturing methods and advantages of prestressed hollow core slab elements are described. Subsequently, after the load carrying characteristics of these elements are emphasized, the connection detailes are illustrated with their design calculation techniques. In addition, analysis and design of hollow core slab elements under the horizontal and vertical loads are discussed. The design procedures are presented together with numerical examples in accordance wlth the ACI 318-83 and TS 3233, codes. Furthermore, special design considerations are also explained with numerical illustrations. Finally, the basic advantages of the use of these prestressed prefabricated elements in housing construction are summarized.
