Reinforced Concrete Wall Rebar Spacing Chart

Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.

Reinforced concrete wall rebar spacing chart.

Where can we get one. 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. There are many variables that influence the decision of how much space to leave including the maximum load the slab is likely to have to support the bearing capacity of the soil the diameter of the reinforcing rebar the likelihood of frost heaving the slab and whether or not the slab is on a level grade. Lap splice lengths are always shown on placing drawings and will be found either in the details lap charts or in the general notes.

There s no generally accepted rule of thumb as to how to space rebar in a concrete slab. Strength reduced from 136 7 to 114 9 in kips. Exact spacing width 16 middle space 10 total bar length 416 9 ft including 10 waste lap. The length of a lap splice varies with concrete strength type of concrete the yield strength grade of the reinforcing bars bar size bar spacing concrete cover and the amount of ties or stirrups.

Somewhere we saw a picture of a wall chart showing rebars full size and giving handy reference information. If your wall is over 40 feet long it will add 2x the amount of overlap required. If your wall is over 20 feet long it will add the amount of overlap required.
