If bending moment is

*M*, shear force is*F*effecive depth is*d*, lever arm is*l*area of reinforcement is_{a}*A*and sum of the circumferences of main reinforcement is 0, the bond stress based on working stress method, is_{s}27.

The horizontal portion of a step in a stairs case, is known as

28.

The length of lap in tension reinforcement should not be less than the bar diameter x (actual tension / four times the permissible average bond stress) if it is more than

29.

If

*K*is a constant depending upon the ratio of the width of the slab to its effective span*l*,*x*is the distance of the concentrated load from the nearer support,*bw*is the width of the area of contact of the concentrated load measured parallel to the supported edge, the effective width of the slab*be*is30.

If

*W*is total load per unit area on a panel,*D*is the diameter of the column head,*L*is the span in two directions, then the sum of the maximum positive bending moment and average of the negative bending moment for the design of the span of a square flat slab, should not be less thanQuick links
