RE: CMU wall effective length

[Subject Prev][Subject Next][Thread Prev][Thread Next]
1997 UBC 2106.2.7 indicates 4*t+bearing but you cannot transmit load across
continuous vertical joints [Section 2106 "general design requirements"].
This is in the general design requirements and I cannot anywhere the UBC
masonry "strength design" slenderwall section contradicts it.

Subject: CMU wall effective length

For a vertical point load on a masonry wall, what is the common
practice for determining the effective length for which this
load can be spread?  Would the 4t+bearing area rule apply
or should a sloped projection be used?
