Masonry Lintel Point Load

Masonry Lintel Point Load

Masonry Lintel Point Load

(OP)
I am designing a lintel that supports CMU wall.  The effective 45-degree triangle is being utilized for design.  There are a few point loads that are need to be incorporated into the design.  I have all these loads figured, but my question is:  Are the point loads that are in the effective area dispersed as a uniform load or a triangular load?  

This is a little difficult to explain, what I am looking to perform, but if you have the Masonry's Designer's Guide 4th Edition, view pages 11-25,26 and figure 11.4-9.  The shaded area from the point load, how is that dispersed on the lintel.  Thanks for the help, and sorry for the confusion this may cause.

RE: Masonry Lintel Point Load

It looks like its a triangular load partially distributed on the lintel, the dark shaded triangle.  That's in the last paragraph before 11.4.5 on 11-25.

RE: Masonry Lintel Point Load

It is applied as a distributed load.  The magnitude of the distributed load is w=p/a.  p=point load.  a=1.15*h.  h is the distance from the application of the point load, i.e. top of wall, to the top of the lintel.  The point load spreads at a 30 degree angle from vertical.  only apply the distributed load to the appropriate length along the lintel from geometry.
