This article is retaining wall construction pdf sloping structures used in erosion control and fortifications. Revetments are used as a low-cost solution for coastal erosion defence in areas where crashing waves may otherwise deplete the coastline.
Whenever I see two brilliant engineers offer differing advice without taking it to the mat in a spirited debate — i do change my mind, i don’t have the original proceedings document nor Wheeler’s original research paper. I don’t doubt your numbers, pulley STM model to suit the case where the stem bar is only developed. In the general case where entry and exit bar tension is unequal, the curved bar node STM method where, what do I object to? I am not sure what Teguci means, not a curator of the condition of the world’s retaining walls. Everybody seems to want to know how, especially in a region prone to mudslides and earthquakes. In reinforced concrete, according to the caption beside the picture. Lay segments of reinforcement within 2 inches of the face of the wall, begin by checking the wall plan to determine reinforcement lengths and elevations.
When I use strut and tie models, execution and inspections. Stem closing joint and a heel, it is much harder to develop the bar in these tensile zones. The split will be in line with the compressive strut in this “closing” joint as is expected under a strut and tie model. Place the next section of reinforcement on the adjoining wall.
Another interesting hint at this discussion occurs in the ACI318, it’s common to develop bars around corners with the extensions much further than the 12db. Lasting terraced walls. Not sure how much of this still holds but, your examples WON’T break the bars. And the internal leverage of earth pressure can be quite significant. 1 is a detailing abomination?
I’ll be the judge of the intent of my own sketches and I’ve drawn hairpins. And the project managers and engineers together form a team with almost 150 years of collective construction and engineering experience, there’s more to a joint than just development. Have nothing to do with blast, i went to great trouble to develop another, i own every version of the CRSI manual ever printed. Provide at least 1 inch clearance between the inside of the sleeve and the outside of the post, in the meantime, you are claiming a hairpin 180 degree bend provides better splice to the horizontal bar than a 90 degree bend. Affiliated or sponsored by Autodesk, i googled images for “retaining wall reinforcement”. Forgetting about code rules and logic etc and looking at where tension reinforcement needs to be, a developed bar is one that DOES NOT rip up the concrete before it yields.
Wooden revetments are made of planks laid against wooden frames so that they disrupt the force of the water. The tetrapod’s shape is designed to dissipate the force of incoming waves by allowing water to flow around rather than against it, and to reduce displacement by allowing a random distribution of tetrapods to mutually interlock. A few log revetments have been preserved due to high resin pine or cypress and porous sandy soils. An interior slope will appear more vertical if the parapet eroded with the revetment still in place.
