Reinforced Concrete Retaining Wall Design
Column chart generation to bs 8110 by reinforced concrete council.
Reinforced concrete retaining wall design. F c 3000 psi fy 60 ksi natural soil development of structural design equations. Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used. Reinforced concrete and reinforced masonry walls on spread foundations are gravity structures in which the stability against overturning is provided by the weight of the wall and reinforcement bars in the wall. Although retaining wall was the subject of the last post their design was not covered.
Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab. Two way slab design to bs 8110 by reinforced concrete council. Strength reduced from 136 7 to 114 9 in kips.
Coefþcient of friction is 0 4 and the unit weight of reinforced concrete is 24 knm 3 1. Two equations are developed. Reinforced concrete retaining wall design to bs 8110 by the concrete center. Subframe analysis to ec2 by reinforced concrete council.
2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16. The following are the main types of wall. Calculate ground bearing pressures. The base is divided into two parts the heel and toe.
The primary difference between them is their height. Determine the factors of safety against sliding and overturning. In this example the structural design of the three retaining wall components is performed by hand. Two equations are developed in this.
Despite the many references a single volume on retaining wall design for the professional practitioner and civil engineering student could not be found. Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions. Numerous textbooks and technical papers on soil mechanics foundation engineering concrete design masonry design and in all sorts of related topics. There are three different forms of this type of wall all of which are designed to resist overturning and sliding failure.
F c 3000 psi fy 60 ksi o development of structural design equations. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria. In this example the structural design of the three retaining wall components is performed by hand.
