Design of 10m Wall
Design of 10m Wall
(OP)
My manager asked me to design a solid perimeter fence 10m high and 120m in length. This would be my first time to design "10m high" wall, I asked my manager if I could use a wire mesh to reduce wind load because the winds here goes from 200-250 kph. But he wanted it to be a solid wall (CHB). My question is what are the other option I can offer or What are the things I should consider for my computations??

Re-inforced concrete maybe, or perhaps a pyramid shaped CHB wall? or lots of long steel beams cast into the ground.
Other option - Find a better manager.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

200 - 250 kph cannot be "normal" but might be a hurricane/typhoon loading.
Try a shallow V-shape of alternating 20 meter long sections repeating down the whole length. Each V will reinforce the next against wind forces - you've got to plan for winds coming from either direction from the eye of the storm. Makes the foundation less expensive since the moment is resisted at both ends of each wall section.

Put footings between piling to support blocks.
Fill in between the HP with reinforced CHB...done.
Glad there are no stated budget requirements... but is soil properties permit, may actually be a viable proposal.

Thanks to everyone for all your suggestion and ideas. at least I have now an idea on what to consider.

I don't know for sure, but I think the foundations are drilled piers. This seems fairly efficient and simple to build.
The drilled piers will of course be significant with a 12' tributary area of a 33' tall cantilevered wall loading into them.

I picked 1 meter HP spacing just as an illustration that should work (with no calculations). I expect, with proper calculations, HP spacing can be increased. The HP10 size was just for example, too. A larger size could be made to work and allow additional construction tolerance.
