Bar Lapping Formula at JENENGE blog

Bar Lapping Formula. Lap length = 45d, where d is the diameter of the steel bars. Lapping means overlapping two bars side by side to achieve the required design length. During placing the steel in rc structure if the required length of a bar is not sufficiently available to make a design length then lapping is done. Values of α 1, α 2, α 3 and α 5 may be taken from table 8.2; If the diameter of the steel bar used in the column is 16 mm, its overlap or lapping. When the two reinforcement bars have an equal diameter; (refer to the below image) The lap length formula for a column is: This length overlapped by two bars in concrete sections is called lap length or overlapping length, which are calculated separately for beams, columns and slab sections. Lap length (l) = 50d. The lap length can be calculated using the following formula: Bar diameter φ (mm) (?) insert. Valid values from 1 to 100. However, for the calculation of α 3, ∑a st,min should be taken as 1.0·as (σ sd / f yd), with as = area of one lapped bar. Here’s a breakdown of two common approaches:
