Phi retaining wall

The active state occurs when a retained soil mass is allowed to relax or deform laterally and outward (away from the soil mass) to the point of mobilizing its available full shear resistance (or engaging its shear strength) in trying to resist lateral deformation. That is, the soil is at the point of incipient failure by shearing due to unloading in the lateral direction. It is the minimum theoretical lateral pr… http://ecoursesonline.iasri.res.in/mod/page/view.php?id=125171

The total bearing area of three 2x4s is 15 3/4 square inches; two 2x6s have a bearing area of 16 square inches. In bending, however, such as from a wind load, a 2×6 wall is considerably stronger. In tall walls, where column buckling might be a factor, a 2×6 wall would be stronger if a structural sheathing was used. css funny
