Development Length is the shortest length needed for reinforcing bar so that the stresses can induced in the bar can increase from zero to the yield strength of the said bar. The development length is a function of the bar size, yield strength, concrete strength and other factors such as coating of the bar. Also, the development length of a bar is dependent to whether the bar is in tension or compression. Tension development lengths are larges than compression development lengths because in compression, the reinforcing bar gets some help from the concrete, while in tension it does not.

What is the difference between lap splice length and development length for rebars?
The difference between the two is in the application. A development length is the amount of rebar length that is needed to be embedded or projected into concrete to create a desired bond strength between the two materials. The lap splice length is the length two rebar pieces must overlap and be tied together to create a bond as if there was no break and the run is "continuous". So simply put, development is rebar to concrete, splice is rebar to rebar. The lengths of both splice and development do vary. They are dependent upon different factors. These include but are not limited to concrete strength, rebar size, rebar coating and concrete cover or clearance. So when you see a chart on one project, it can differ from another for these reasons.
How do you speed up the strength development of concrete. can you please explain it?
how to speed up the strength development of concrete in civil engeneering

What is the minimum anchorage length on re-bars in concrete cantilever beams?
you can generally use 180 degree hooks, to provide enough anchorage in slabs with no edge beams. use the Ldh formula (12.5.2) of ACI 318-11
What is mean by development length in columns?
Development length is the length overlap of bars tied to extend the reinforcement length. is about 50 times the dia of bar is consider to safe.
