Maximum Reinforcement and Ductility
in Concrete Masonry Shear Walls
Concrete masonry shear walls must possess
sufficient strength to resist axial, flexural, and
shear demands. Additionally, these walls must
satisfy specific detailing requirements as outlined
in the prevailing codes. These requirements
are to ensure that the walls possess adequate
ductility in the event of seismic activity. The use
of maximum reinforcement ratios is intended
to provide ductility by ensuring that the tensile
reinforcement yields prior to crushing of the
compressive zone.
Examples will be provided to illustrate how to
determine the maximum reinforcement permitted
in concrete masonry walls in accordance with
the 2006 International Building Code (IBC) [1].
For masonry design, the IBC references the ACI
530-05/ASCE 5-05/TMS 402-05 [2], which is
also referred to as the 2005 Masonry Standards
Joint Committee Building Code (MSJC).[more]
