Can anyone provide me reference or give guidance on how to account for additional Horizontal Loading due to Wind loading from Wood Fence say 6.0ft high fence (fence footing Founded on Short pile/column)behind my SRW Retaining wall.
I will have to add this force in my Base Sliding & Overturning...
I deal with lots of Precast block making companies that have their own design charts or cook book cross sections demonstrating how high they can go with gravity walls & faster installation. Some of them apply multidepth principle, mass extender blocks/tails at the bottom portion, gabion...
I have a project where we are designing 12 ft high wall in front of a Storm Water detention pond. Due to seasonal water fluctuations the water level at front of the wall will vary. It is also expected at some point 80% of wall in front will have water during peak flow event.
I wall be using a...
How deep the fence post should be grouted on 300lb/ft block module the dimensions of precast module is 6ft L X 2ft W X 1 ft H & wt of each module is 1800lbs. Assuming ht of fence is 3.0ft & post spacing not to exceed 6.0ft
When doing overturning force calculation should i compare Overturning...
How do we distribute Shear Force of 8.0ft Acoustic fence pier buried within the body of MSE wall. The Fence footing is approx 1.0ft offset from MSE wall facing.
Can i ask the Fence Designer to provide me Shear Force distribution diagram & add these forces in Geogrid layers. Since the load...
i have a job whereby i have to account for vehicular barrier approx 4.5ft offset at p/l behind wall is approx 5.0ft high.
The owner Engineer has provided min 6000lbs load . My question is do i have to convert this concentrated load to lb/linear fit. The vehicular barrier wood post is...
Can we design a CMU block retaining wall for at rest condition or Block Retaining wall by their very nature are supposed to be designed for active earth pressure conditions.
Besides increased Geogrid Length and or Larger block wt what would be the other design implications due to higher earth...
If i input say 0.42 PGA value in NCMA design limits max slope above wall (6H: 1V) when doing Seismic Analysis. .
The grading plan from which wall height is picked indicates a 3H: 1V slope above wall.
Increasing the wall height to match the limiting slope (6H: 1V) to satisfy Seismic analysis...
Does anyone have come across a situation whereby the Geogrid retaining wall which has already built in my case approx 4.0m high(13.0 ft) & afterwards Noise fence contractor comes & want to built their structure using vacuum excavation method.
I am concerned they would damage the polyester...
Can any one share a software or spreadsheet on how to calculate horizontal thrust due to wind loading from wood privacy fence offset behind wall for various heights.

What should be the sliding Friction factor for Dry Cast Concrete Modular Block Wall resting on Thickened Granular Pad. Can i use 0.67X phi angle provided by Geo technical Engineer. The Geo technical Engineer is recommending 0.5X phi(36) i.e Tan 18/19 deg which translates into...
What should be the Typical Friction Factor Value Modular Block wall resting over Granular Thickened Pad apparently Geo technical Engineer is asking me to use 0.35 which i think is overly conservative. My allowable friction angle for Engineered Thickened Granular Base is 36 Deg friction angle for...
Our Client a developer requires a retaining wall at a site where the grading height of the wall is about 7.5m (24ft) typically i have seen Segmental Retaining walls with a batter (a setback)in this case the setback causes about approx 1.0m(3.0 ft) of costly real estate land being sacrificed. My...
I am looking for a simple mathematical solution for magnitude of offset surcharge above CMU block wall. The wall above is also modular block wall about 1.2m(4.0ft) high. The lower wall is about 6.0ft high. The offset distance is about 6.0ft.between walls. Do i have to included Dead load...
