Abstract:
Most concrete structures and members are subject to permanent contraction movements due to early age volume changes, drying shrinkage, carbonation and creep. They are also subject to transient movements and rotations caused by fluctuations in humidity and temperature and the application of loads to the structure. In concrete that is restrained from freely contracting, shrinkage and temperature movements will induce tensile stresses and may cause unacceptable cracking. Proper joint design is required to ensure the load-carrying capacity and serviceability of the structure or member is maintained.
