Howdy!
I searched previous threads (like this one: thread255-105369) for some help regarding the design of a counterfort, but couldn't find what i was looking for. I've already designed the wall, heel, and toe according to "Basics of Retaining Wall Design" by Brooks and Nielsen. My question is about the actual reinforcement design of the counterfort itself. Since it is at an angle, I am assuming I need to take the tension in the steel (As×fy) and break it up into horizontal and vertical components. Is this correct or no? The reason I ask is that even though the width of the counterfort is quite long (18ft), I'm coming up with a lot more required area of steel than I was expecting (6.8sq in). Its fairly tall (25ft) but the loads are so high because its for a railroad. So if I could get away with not dividing by sin(theta), that would really help. Anyone out there have experience with this?
Thanks,
Joel
