Book Description
These volumes contain the edited documents presented at the NATO-Sponsored Advanced Research Workshop (ARW) on Partial Pre8tre88ing, from Theory to Practice, held at the CEBTP Research Centre of Saint-Remy-Ies-Chevreuse, France, June 18-22, 1984. The workshop was a direct extension of the International Symposium on Nonlinearity and Continuity in Pre8tre88ed Concrete, organized by the editor at the University of Waterloo, Waterloo, Canada, July 4-6, 1983. The organization of the NATO-ARW on Partial Prestressing was prompted by the need to explain and reduce the wide dirrerences of expert oph:iipn· on the subject, which make more difficult the accep tance of partial prestressing by the profession at large. Specifically, the workshop attempted to: - produce a more unified picture of partial presetressing, by con fronting and, where possible, reconciling some conflicting American and European views on this subject; - bring theoretical advances on partial prestressing within the grasp of engineering practice; - provide the required background for developing some guidelines on the use of partial prestressing, in agreement with existing structural concrete standards. The five themes selected for the workshop agenda were: (1) Problems of Partially Prestressed Concrete (PPC). (2) Partially Prestressed Concrete Members: Static Loading. (3) PPC Members: Repeated and Dynamic Loadings. (4) Continuity in Partially Prestressed Concrete. (5) Practice of Partial Prestressing.

Book Description
The book explores the two opposite natural trends of composite systems: (i) order and structure emerging from heterogeneity and randomness, and (ii) instability and chaos arising from simple nonlinear rules. Providing insights into the rapidly growing field of complexity sciences, the book focuses on the role of complexity in fracture mechanics. It firstly discusses the occurrence of self-similarity and fractal patterns in deformation, damage, fracture, and fragmentation of heterogeneous materials and the apparent scaling of the nominal mechanical properties of disordered materials, as well as of the time-to-failure after fatigue and creep loading. Then the book addresses criticality in the acoustic emissions from damaged structures and tectonic faults. Further, it examines the snap-back instability in the structural behavior of relatively large composite structures in the framework of catastrophe theory, and lastly describes the transition toward chaos in the dynamics of cracked elements.

Book Description
This book deals fundamentally with the basic philosophy, principles and the application of prestressing in structural elements. It also covers the detailed engineering of the structural elements with prestressing forces in terms of analysis and design. Different systems of prestressing, losses in prestressing and evaluation of capacity of prestressed concrete sections in flexure, shear and torsion, the force flow due to prestressing at anchorage zones, the time dependent effects due to creep and shrinkage of materials are explained. The design of prestressed concrete elements is covered with a holistic concept. In case of indeterminate structures, the effect of prestressing while satisfying the compatibility conditions has been clearly explained. The necessary philosophy and the design procedures of partially prestressed elements have been specifically dealt with. Accepted National and International Code provisions for design of prestressed concrete elements under the effect of the various loads have been elaborately discussed with worked out examples.

Book Description
The aim of this state-of-art report is to present current practices for use of precast and prestressed concrete in countries in seismic regions, to recommend good practice, and to discuss current developments. The report has been drafted by 30 contributors from nine different countries. This state-of-art report covers: state of the practice in various countries; advantages and disadvantages of incorporating precast reinforced and prestressed concrete in construction; lessons learned from previous earthquakes; construction concepts; design approaches; primary lateral load resisting systems (precast and prestressed concrete frame systems and structural walls including dual systems) diaphragms of precast and prestressed concrete floor units; modelling and analytical methods; gravity load resisting systems; foundations; and miscellaneous elements (shells, folded plates, stairs and architectural cladding panels). Design equations are reported where necessary, but the emphasis is on principles. Ordinary cast-in-place reinforced concrete is not considered in this report. This fib state-of-the-art report is intended to assist designers and constructors to provide safe and economical applications of structural precast concrete and at the same time to allow innovation in design and construction to continue. This Bulletin N° 27 was approved as an fib state-of-art report in autumn 2002 byfib Commission 7, Seismic design.
