560 N/mm2 415 N/mm2 250 N/mm2 1500 N/mm2

Compressive steel is under-stressed Shear reinforcement is more Concrete is not stressed to its full value Tensile steel required is more than that for a balanced section

Tangent modulus Secant modulus Initial tangent modulus Short and long-term values of Young's modulus

Thrust Torsion Shear Bending moment

Collapse Deflection Durability Cracking

span/depth ratio water/cement ratio Aspect ratio Modular ratio

Shear force is constant Bending moment is zero Shear force is zero Bending moment is constant

Reduction in depth No change in depth Increase in depth Increase in width

Independent of long or short span Dependent on both long and short spans Primarily a function of the short span Primarily a function of the long span
