Catenary panel retaining wall
A retaining wall system, retaining wall panel, and method of constructing a retaining wall, wherein panels of the retaining wall define an arched or curved profile in plan view, for example following a catenary curvature, with the wall panel curvature being concave in a direction extending into the backfill area behind the retaining wall. The curvature resists backfill loading on the panel and evenly distributes the load across the panel without significant stress concentrations and transfers the load to posts or columns to which the panels are mounted.
1. A retaining wall system comprising:
a plurality of support posts arranged in a spaced array; and
at least one wall panel configured for engagement between a first support post and a second support post, the at least one wall panel having a plan profile defining a curvature, wherein the curvature profile of the at least one wall panel defines a catenary curve.
2. The retaining wall system of claim 1 , wherein the support posts comprise a wood core and a polymeric cladding.
3. The retaining wall system of claim 1 , further comprising decorative caps for attachment to the support posts.
4. The retaining wall system of claim 1 , further comprising a plurality of fasteners for attachment of the wall panels to the support posts.
5. A panel for a retaining wall, the panel comprising a front face, a back face, a top edge, a bottom edge, a first side edge, a second side edge, and attachment flanges extending along the first and second side edges of the panel, wherein the panel defines a plan profile from a top perspective having an arched curvature.
6. The panel of claim 5 , wherein the arched curvature of the panel profile defines a catenary curve.
7. The panel of claim 5 , comprising a material of construction selected from the group comprising plastic, thermoset composite, fiber-reinforced plastic (FRP), vinyl, polyvinyl chloride (PVC), steel, aluminum, other metals, composites, and combinations thereof.
8. A method of constructing a retaining wall, said method comprising:
installing a plurality of posts anchored in or to a ground in a spaced array; and
mounting at least one wall panel between adjacent pairs of the plurality of support posts, the at least one wall panel having a plan profile defining a curvature, wherein the curvature profile of the at least one wall panel defines a catenary curve.
9. The method of claim 8 , further comprising backfilling behind the at least one wall panel.
10. The method of claim 8 , further comprising installing a drainage system behind the at least one wall panel.
11. A retaining wall system comprising:
a plurality of support posts arranged in a spaced array; and
at least one wall panel configured for engagement between a first support post and a second support post, the at least one wall panel having a plan profile defining a curvature in the shape of a catenary curve corresponding to a formula
