Factors affecting Lapping Length

This video shows the factors that affects the lapping length. There are following factors which can affect the lapping length enormously;
1. Diameter of rebar increases then lapping length also increases
2. Grade of rebar increases then lapping length also increases
3. Grade of concrete increases then lapping length decreases
4. Also depends on the type of rebar.

Factors affecting bending moment in beam: 1. Span length (L) is directly proportional to bending moment 2. Load (W) is directly proportional to bending moment Factors affecting shear force in beam: 1. Load and support reaction is directly proportional to shear force in beam

Why LL increases due to increases of steel grade?
