Discusses the location of expansion joints in concrete buildings. The writer undertook a research program in 1958 that employed laboratory, field and mathematical investigations. These research efforts lead the writer to conclude that expansion-contraction joint spacings should be determined more rationally and should reflect the type of materials and construction methods used, and the degree of serivce exposure to be expected.
