Description
Slender precast concrete spandrels that span longer distances increase the cost effectiveness of precast concrete parking structures. ■ This paper provides realistic estimates of long-term deflections for the next generation of spandrels and offers an understanding of the parameters that affect these deflections. ■ The sensitivity of long-term deflections to parameters such as spandrel type, span length, beam width, concrete curing, creep, shrinkage, and load eccentricity and magnitude is presented.
