Civil Engineering :: Structural Design Specifications

The area of the concrete in compression plus the area of reinforcement transferred on the basis of modular ratio, is called

If D is the overall thickness of the slab, the diameter of the reinforcing bars should not exceed

The gap between web plates and flange plates for fillet welds should not be more than

A continuous beam shall be deemed to be a deep beam if the ratio of its effective span to overall depth, is

The depth 'd' of webs without horizontal stiffeners and consisting of tongue plates is taken lesser than the depth of the girder between the flanges less the sum of the depth of the tongue plates, and

For design of a column the eccentricity of loading shall be taken as the distance from the assumed point of application of the load to the centroid of the column, subject to a minimum of

If l is the effective span in metres and D is overall depth of the section in mm, the structure may be accepted after 24 hour load test, provided the maximum deflection in mm is less than

The approximate value of torsion constant k for a box of depth d, width b, and having uniform thickness t, is

In the formula a + bk for the calculation of the net effective section of single angles in tension connected by one leg only, the value of k, is

The concrete is deemed not to comply with the strength requirements if the strength is less than the greater of
