Abstract

Describes the types of movement which affect the performance of buildings and building elements. Methods and data are given to enable amounts of movement to be estimated, and design details are put forward to satisfactorily accommodate these movements. Sources of movement considered include: temperature and radiation effects, early age thermal movements of concrete, shrinkage and expansion resulting from moisture movement, elastic and creep deflections under load, and foundation movements. Dynamic response to wind or ground motion is included, because this is often an important design criterion for taller structures. Restraints to movement are often present, frequently generating significant forces. This study describes how these forces can be reduced, either by designing elements to minimise the restraints to movement or by providing suitable movement joints. In concrete elements, imposed tensile strains can be distributed by reinforcement.
