Some useful notes on steel structure
Sami Ullah, the eminent engineer, presents another useful video tutorial for civil engineering students. This video provides detail information on steel structures.
Standard bar splices (lapping length for the steel) for tension member applicable to all members :-
For nos #3, 4 and 5 bars splice length is = 12 inches
For no #6 bar splice length = 22 inches
For no #8 splice length = 40 inches
All the positive (bottom) reinforcement is demonstrated as solid lines in the drawing.
All the negative (top) reinforcement as a dashed alias broken line in the drawing.
Clear cover for slab = 0.75 inches
Clear cover for beam = 1.5 inches
Clear cover for column = 1.5 inches
Clear cover for foundation = 2.5 inches
The applied concrete should contain a minimum 28 day’s cylinder crushing strength of 3000 psi.
Splice length of steel for M20 concrete :-
Slab = 60d
Column = 45d
Beam = 60d
Here, d denotes dia of steel that is utilized in a slab.
