Title: The Economical Role of Contraction Joints in the Design of Reinforced Concrete Walls
Author(s): S. M. Sandrossadat-Zadeh
Publication: Special Publication
Appears on pages(s): 1099-1110
Keywords: Concretes; control joints; structural design; walls.
Abstract:Changes in the temperature and in the moisture content of the concrete cause dimentional changes which , if resisted externally may crack the concrete. The distribution and width of such cracks can he controlled by reinforcement together with the provision of movement joints.The effect of contraction joints on the degree of restraint has been studied by modelling walls with different length to height ratios through a Finite Element pakage.Three different wall end houndry• conditions have been considered .It has been shown that for walls with lower values of length to height ratio implementing partial contraction joint , instead of full contraction joint can result in a more economical design.
