Title: Cracking of Concrete Members in Direct Tension
Author(s): ACI Committee 224
Publication: Journal Proceedings
Appears on pages(s): 3-13
Keywords: cracking (fracturing); crack width and spacing; loads (forces); reinforced concrete; restraints; stiffness; strains; stresses; tension; tensile stress; volume change.
Abstract:This report is concerned with cracking in reinforced concrete caused primarily by direct tension rather than bending. Causes of direct tension cracking are reviewed, and equations for predicting crack spacing and crack width are presented. As cracking progresses with increasing load, axial stiffness decreases. Methods for estimating post-cracking axial stiffness are discussed. The report concludes with a review of methods for controlling cracking caused by direct tension.
