Reinforced Concrete Wall Construction Details

These panels are created at the work site using wood forms rebar and concrete.

Reinforced concrete wall construction details.

Reinforced concrete wall is designed as a compression member. Concrete masonry is used to construct various foundation wall types including full basement walls crawlspace walls stem walls and piers. Reinforcing bars are placed in a concrete member with a minimum concrete cover to protect it from weather fire and other effects. Concrete masonry is well suited for below grade applications because of its strength durability economy and resistance to fire insects and noise.

Tilt up construction features series of concrete panels tilted up into place to form a building s exterior wall. It is constructed as a load bearing structure to transfers loads from floor to the wall below or to the foundation in addition to divide spaces in multi storey buildings. This type of walls has vertical stem monolithic with the base. Next concrete is poured into the forms and finished.

The modular nature of concrete masonry allows floor plan and wall height changes to be easily accommodated as well. Reinforced concrete approach slab 30 ft. Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used. Reinforced concrete cantilever types of retaining wall are recommended for heights up to 7 m.

Plain concrete wall when reinforcement 0 4. Strength reduced from 136 7 to 114 9 in kips. Tial basement walls and the national ready mixed concrete association ref. 500 d 400 w 35fcu mpa with a symmetrical flange width 2160mm and flange depth 150mm carrying a total factored uniformly distributed load of 62 5kn m.

A slender section can be used in this retaining wall the tensile stresses within the stem and the base is resisted by steel reinforcement. Minimum cover requirements for nonprestressed cast in place concrete construction are given in table 20 6 1 3 1 of aci 318 14 building code requirements for structural concrete. Construction of concrete walls is a crucial phase in building construction. Manual for design and detailing of reinforced concrete to the september 2013 code of practice for structural use of concrete 2013.

The forms are shaped and rebar cut to match final designs. 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. 4 recommends a contraction joint spacing of 30 times the wall thickness or 20 feet for an 8 inch thick wall 30 8 240 inches 20 feet. 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.
