Deals with the mahematical models and modelling techniques used to predict creep and shrinkage in concrete.
Long-time serviceability is an important problem for concrete construction, as concrete structures can suffer from excessive deflections, cracking, corrosion or other impairments, the causes of which often involve concrete creep and shrinkage. The damage and residual stresses produced by creep and shrinkage effects may reduce the safety margin against the ultimate collapse state under live load. Therefore, improvements in the design of concrete structures are an important objective of research. This book details the proceedings of a symposium on these design improvements, held at Northwestern University, Evanston, Illinois in August 1986. Over 90 participants from 27 countries took part in lectures and discussion sessions, the summaries of which are outlined.
