Abstract

Explores types, sources, restraint and strain-induced forces of movement that can affect concrete elements over time. Examines the cumulative effect, considers why cracks matter and looks at avoiding or controlling cracks. Discusses the factors of free movement including early-age contractions, long-term shrinkage and temperature variations. The section looking at creep covers estimation, effective elastic modulus and the relief of stress. Considers the mitigation measures available and looks at some practical applications.
