the backfill is horizontal. The At-a-Glance tab shows a summary of the design for a quick overview of your work as you go. To further understand the designed approach, here is a worked example of the design of the retaining wall. The Stem tab shows the pressures acting on the stem, and the shear and moment diagrams when the stem is subjected to the lateral pressures, considering the counterforts as the supports.4.- Enter the rebars in the stem, counterforts, and footing.

The purpose of this article is for the reader to fully understand the principle behind it.

Types of Retaining Walls Buttress Wall •Similar to counterfort wall, but bracing is constructed in front of the wall •Bracing in compression •More efficient than counterforts, but no usable space in front of the wall. Worked Example: Figure A.1-Retaining Wall Cross Section.

Design the counterfort retaining wall.1.- Enter the geometric dimensions of the wall. This document is a step-by-step design example of a typical counterfort retaining wall using ASDIP RETAIN.As an example, consider the retaining wall shown below, which supports a flat backfill load. The soil bearing capacity is 4 ksf. Soil Mechanics Simplified 4. As a rule of thumb, the footing length should be about 0.7 H = 16 ft long, and about 1/4 should be the toe = 4 ft.

<> Building Codes and … Here the transverse supports are known as “buttresses”, hence the name buttress wall. We will use the Rankine theory to calculate the lateral soil pressures. This pressure tends to deflect the wall outward. • Buttress wall-RCC 6.

Due to the wall height of 25 feet, the use of counterforts has proven itself to be a more economical solution. Earth Pressure (P) 8 Earth pressure is the pressure exerted by the retaining material on the retaining wall. Posted: Sat May 16, 2015 10:16 am Post subject: Design of Buttress RCC retaining wall of 12m height: Dear All, I need some help from experienced members for the following problem with references to design calculations if possible: 1.The problem is to retain earth to a height of 12m, may be counterfort retaining wall should solve the problem. In this case, the stem height is 25'-0". Basics of Retaining Wall Design 10 Editionth A Design Guide for Earth Retaining Structures Contents at a glance: 1.
