Development Length in Rcc

Development Length Calculation as per Indian Code Development length  is the extra length of bar provided beyond the required section in order to ensure the following; To develop a safe bond between the bar surface & the concrete so that no failure due to slippage of bar occurs during the ultimate load conditions. Also, the extra length of the bar provided as development length is responsible for transferring the stresses developed in any section to the adjoining sections (such as at column beam junction the extra length of bars provided from beam to column). Importance: Provision of appropriate development is an important aspect of safe construction practices, proper development length in reinf. bars shall be provided as per the steel grade considered in design otherwise in scenarios where less development length against the required is provided the structures will be prone to encounter  failure due to slippage of joints, bonds, anchors & Laps, in ...
