Masonry Guardwall Design

[shp6]

I am currently designing a "masonry guardwall". The wall is 5'-00" tall and sits on top of a stone retaining wall. The thickness of the masonry wall is 16" and the reinforcement will be extended from masonry wall to stone wall and maintain at least a development length. The stone retaining will require a type S motar.

According to IBC, the traffic load for this guardwall is 6,000 lbs. I am thinking to use the 6,000 lbs of load to apply to the top of a 5'-00" wide by 5'-00" tall wall as the design model and then design rebar for flexural and shear. It is simply considering the load is applied at top of a 5' wall and 45 degree force transfer to the base. Is this assumption reasonable and conservative?

Is there any design samples somewhere which I can follow?

Thank you for your help.

It sounds reasonable. AASHTO LRFD shows a procedure in Chapter 13.

I attached a file from NHI 13061, which is an FHWA LRFD training manual; go to Section 16 (railings & barriers) and you'll find the same info from AASHTO.

The entire training manual can be downloaded at:

I think you're going to have a real challenge making a masonry wall work for that kind of load. You might have to use a concrete wall and face it with masonry. Plus when you follow the load into the stone wall, you're not done with it just by developing the bars. You need a mechanism to carry the load to its foundation.
