This second edition of Precast Concrete Structures introduces the conceptual design ideas for the prefabrication of concrete structures and presents a number of worked examples of designs to Eurocode EC2, before going into the detail of the design, manufacture, and construction of precast concrete multi-storey buildings. Detailed structural analysis of precast concrete and its use is provided and some details are presented of recent precast skeletal frames of up to forty storeys.

The theory is supported by numerous worked examples to Eurocodes and European Product Standards for precast reinforced and prestressed concrete elements, composite construction, joints and connections and frame stability, together with extensive specifications for precast concrete structures. The book is extensively illustrated with over 500 photographs and line drawings.
The intact concrete between adjacent cracks can still carry tensile stresses after cracking occurs in reinforced concrete members. This phenomenon known as the tension stiffening is principally generated due to the bond between reinforcing bars and surrounding concrete. Cracking and tension stiffening are considered among complex phenomena of reinforced concrete mechanic. In this subject, a variety of constitutive laws, many approaches and various techniques have already been proposed to predicate the tension stiffening behaviour in RC and FRP reinforced concrete structure. Many works have been shown that neglecting the tension stiffening contribution leads to soft structures. The economy in reinforcement when the tension stiffening effect is taken into account during the procedure of the design has been quantified.
Today, the Australian Concrete Structures Standard, AS 3600, adopts a unified,performance-based approach to design for all reinforced concrete structuresand members, irrespective of whether or not prestress is used. Thisintegrated approach has removed unnecessary restrictions on design and hasprovided significant advantages to innovative designers. This in turn hasresulted in partial prestressing becoming the design norm, and the term prestressedconcrete now means, simply, structural concrete with prestress.
