masonry guardwall design
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:

thanks a lot for your help.
you're welcome.
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.
