TIERED RETAINING WALL A combination of two or more retaining walls in a parallel step design for which the spacing of any two tiers is less than two 2 times the height of the lower tier. The exposed height of a tiered wall is measured vertically from the lowest point of the finished final
A retaining wall includes any wall constructed of brick, stone ,reinforced concrete ,concrete blocks ,wood ,timber ,logs or any other materials designed to retain any excavation. Retaining walls are designed to ensure stability against overturning, sliding, excessive pressure and water uplift.
Some of the wood walls are desired for specific rooms such as lavatories, conservatories, dining room, bed-room and different sections depending on the user needs. Conclusion The integration of both architectural engineering as well as creative arts bring forth beautiful wood wall retaining designs.

TIMBER CRIB RETAINING STRUCTURES Robert L. Schuster,* U.S. Geological Survey, Denver; of the American Wood Preservers Institute standard design for timber crib walls 4 . 118 Although log crib walls are not subject to exact engineering design and analysis, many have been and are being built. For example, the Washington State Highway De-
This document is intended to provide guidance for the design and construction of timber retaining walls in residential settings and TIMBER RETAINING WALLS FOR RESIDENTIAL APPLICATIONS TECHNICAL DATA SHEET refer to a structural/geotechnical engineer for a specific design.
The wall portion of the design is similar to the cantilever retaining wall the wall is fixed at the bottom to the grade beam but in addition to that the engineer has to make sure that the grade beam is sufficiently designed to take the moments and shears from the wall and pass it onto the piers.
