Structure: Dimensions
In accordance with general principles which limit the location of
penetrations through concrete shear walls, these penetrations are
organized as follows:
a. The edges of the shear wall are free of penetrations. The minimum
width of this edge is approximately 3'6".
b. The penetrations are aligned vertically and horizontally to allow a
regular reinforcing pattern.
c. Where the size and spacing of openings is such that the wall does
not act as a single element, that part of the wall is eliminated as a
potential shear resisting element.
d. The spaces between the penetrations are more or less equal, and
in the range of three feet.
e. The combined widths of all the openings in one row is not more
than 50% of the plan length of the shear element.
f. The combined height of all openings above each other is not more
than 50% of the height of the shear element.
The principles described above apply to concrete shear walls. The
openings in diagonally braced frames are limited only by the size and
location of the members themselves.
