Abstract:
The 1963 ACI Code criteria for columns are compared with the 1956 Code. Comparative costs are presented for columns showing the effect of four basic variables: the type f column, concrete strength, reinforcing steel strength, and percentage of steel. lapped column splices and four types of butt splices are discussed. A sample column schedule for columns with butt splices is presented showing the intended bar and tie arrangement, splice locations, and dowel patterns. The ultimate strength design and working stress design methods for columns are compared under the 1956 and 1963 Code. The procedure for constructing a working stress design interaction diagram is demonstrated. The 1963 Code criteria for length of columns and capacity of long columns are discussed and compared with the 1956 Code.
