Thermal Movement Design Procedure for Steel and

These thermal movements are used to design the expansion joints and bearings. It is important that the magnitude and direction of the design movements be predicted with reasonable accuracy, since extremely large forces occur if movement is restrained. These forces may lead to severe damage if movements are not properly accommodated through
