The design of structures in general, and prestressed concrete structures in particular, requires considerably more information than is contained in building codes. A sound understanding structural behaviour at all stages of loading is essential. The aim of this book is to present a detailed description and explanation of the behaviour of prestressed concrete members and structures both at service loads and at ultimate loads and, in doing so, provide a comprehensive guide to design. The design criteria and procedures contained in several major building codes, including ACI 318-83, BS 8110:1985, and AS 3600-1988, are also presented. Each aspect of the analysis and design of fully-prestressed and partially-prestressed concrete members is approached from first principles and illustrated by worked examples. The text is written for senior undergraduate and post-graduate students of civil and structural engineering and also for practising structural engineers.

Part 1 Basic concepts: methods of prestressing; transverse forces caused by draped tendons; calculation of elastic stresses; flexural behaviour; design procedures. Part 2 Design properties of materials: composition of concrete; strength and deformation of concrete; predictions of the creep coefficient and shrinkage; thermal expansion; steel used for prestressing; steel relaxation; non-prestressed reinforcement. Part 3 Design for serviceability: stress limits; determination of prestress and eccentricity in flexural members; cable profiles; short-term analysis of cross-sections; time-dependent analysis of cross-sections; losses of prestress; deflection calculations. Part 4 Ultimate flexural strength: flexural behaviour at overloads; flexural strength theory; approximate code-orientated procedures; design calculations; flanged sections. Part 5 Design for shear and torsional strength: shear in beams; torsion in beams; shear in slabs and footings. Part 6 Anchorage zones: pretensioned concrete-force transfer by bond; post-tensioned concrete anchorage zones. Part 7 Composite construction: types and advantages of composite construction; behaviour of composite members; stages of loading; determination of prestress; methods of analysis at service loads; ultimate strength analysis; horizontal shear transfer; untimate shear strength. Part 8 Design procedures for determinate beams: types of section; initial trial section; design procedures - fully prestressed members, partially prestressed beam. Part 9 Statically indeterminate members: tendon profiles; continuous beams; statically indeterminate frames; design of continuous beams. Part 10 Two-way slabs - behaviour and design: effects of prestress; design approach; one-way slabs; two-way edge-supported slabs; flat plate slabs; flat slabs with drop panels; band-beam and slab systems. Part 11 Two-way slabs - serviceability: the balanced load stage; initial sizing of slabs; a review of simplified slab deflection models; long-term deflections. Part 12 Compression and tension members: types of compression members; classification and behaviour of compression members; cross-sectional analysis compression and bending; slenderness effects; reinforcement requirements in compression members; tensio members. Appendix: alternative models for creep and shrinkage - the ACI Z09 method (1978), the CEB-FIP methods (1978).
