Reviews the application of load balancing in a broader context as the emerging standard for analyzing post-tensioned buildings. Terminology, concepts, and current procedures used in the extended scope of load balancing are presented, and the governing relationships are introduced and discussed. The redistribution of elastically computed moments due to limited joint plastification is examined, and numerical examples illustrate the application of load balancing to more complex structures and the importance of faithful representation of balanced loading.
