Occasionally the existing structural or nonstructural systems of a building being strengthened require the imposition of deflection constraints or limits in order to avoid an undesirable behavior of existing (old) components. This usually takes the form of restricting the interstory displacement estimated to exist due to a design earthquake input. This paper discusses one method of providing deflection constraints without compromising window openings or the operation of the structure.
