Design of 42" concrete parapet barrier rail
Design of 42" concrete parapet barrier rail
(OP)
I have designed a 15' reinforced concrete cantilever retaining wall adjacent to a roadway. The client desires to extend the wall an additional 42" to create a rigid concrete barrier rail. The aluminum railing will then be attached at the termination of the concrete rail. How should the additional 42" be analyzed and designed considering LRFD and TL-2 requirements? It doesn't seem correct to consider yield line analysis in this situation. Or would beam theory be applicable if a 42" cantilevered beam is considered?

I find it hard to believe that #7@12 carried an additional 42" or so will not win against a car. I also think that the car will be crushed snd stopped before the tow of the wall sees any additional load, if any.
