RE: point load vs. effective width

[Subject Prev][Subject Next][Thread Prev][Thread Next]
What is the wall made of?  If it's concrete or masonry (or some other type
of continuous construction) then you could probably get a formula out of
Roark's book to approximate this.

Subject: point load vs. effective width

I have a project that needs to design a free-standing wall subjected to a
point load perpendicular
to the wall (out-of-plane point load). The point load is located at 2'-0"
above the bottom of the
wall. The question is that what width of the wall (at wall length direction,
not thickness
direction; the width is located at bottom of the wall) should be used to
resist the point load ?
Should be spread at a ratio of height:width=1:2 at each side of the point
load (that means
width=8') or even height:width=1:3 (width=(2)(2)(3')=12') ? Or any other
width should be used ?
Does any one know any reference or test results regarding this issue ?

Thanks in advance.
