Reinforced Concrete Wall Section Detail

Section 11 7 5 of aci 318 14 requires that for walls with one layer of reinforcement in both the longitudinal and transverse directions at least one 5 bar must be provided around an opening.

Reinforced concrete wall section detail.

All exterior walls and interior load bearing walls should be supported on reinforced concrete strip footings. Strength reduced from 136 7 to 114 9 in kips. Type m 1 and m 3 modified std. This type of walls has vertical stem monolithic with the base.

A solid top course on the below grade concrete masonry wall spreads loads from the building above and also improves soil gas and termite resistance. Similarly at least two 5 bars are required around openings in walls that have two layers of reinforcement in both directions. In most cases vertical reinforcement is positioned towards the interior face of below grade walls to provide the greatest resistance to soil pressures. 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.

Plain concrete wall when reinforcement 0 4 reinforced concrete wall when reinforcement gt. The stages of design for a reinforced concrete wall can be summarised as follows. Curb or curb and gutter adjacent to roadway and or sidewalk across bridge. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.

Establish design life of the structure to which the wall is to form a part. Download free high quality cad drawings blocks and details of concrete organized by masterformat. Reinforced concrete wall is classified as. Reinforced concrete approach slab 30 ft.

Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m. Reinforced concrete wall is used in case where beam is not provided and load from the slab is heavy or when the masonry wall thickness is restricted. Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab. 5001 m drop inlets for use in front of r e.

Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used. The base is divided into two parts the heel and toe. A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement. The foundations should generally be located on a layer of soil or rock with good bearing characteristics.

Determine actions on the wall and their combinations. Both set parameters for the concrete strength of the wall its thickness and cover to reinforcement. The heel is the part of the base under the backfill.
